67: I have a few questions regarding the plants and animals on the Channel Islands.

After learning from Dr. Atwater about the geological origin of the islands and their trip up from the San Diego area by way of plate movement I became curious about the Torrey Pine being in both the San Diego area and on Santa Rosa Island.

Does this mean the pines traveled up on the island?
Could this also mean other plants made their way up in the same way?
Are there certain plants that did not exist at that time indicating a trip across the channel the only logical explanation?
Might animals have traveled up on the island the same way or is millions of years too long ago for contemporary animal species?
What animals other than the Pygmy mammoth were once out there but are now no longer around?
We are studying about plant and animal dispersal and the effects of island isolation on these plants and animals and these and other questions arise. We are aware that certain conditions must be present for a plant or animal to establish itself on the island but we would like to know if there is any evidence of species being there but not making it to present day, either due to climatic changes, predation, influence of man, or some other reason.
Any information or direction towards sources would be greatly appreciated.

70: We have been learning about genetically modified plants, such as a strawberry that has an *antifreeze* gene from a flounder inserted to resist frost. Now, if this strawberry (with an *extra* allele inserted) is crossed with a normal strawberry plant, what phenotype will be expressed, since there will not be two pairs of alleles for that particular chromosome? We thought it could be like a fragile X thing (just one copy), but we're not sure.

85: Hi Science Line, I had my secondary science student teachers conduct a toxicology investigation following a standard protocol. They investigated the effects of a toxin of their choice (diet Pepsi, nail polish remover, etc.) on the germination and growth of lettuce seeds. They used six different concentrations of the toxin, three plates per concentration, five seeds per plate. They counted the number of seeds germinated per treatment and measured the length of the seeds' radicle in mm. My questions: (1) What is the appropriate number of significant figures to use when calculating the average germination and average radical length? (2) If a seed hasn't germinated or has germinatd but has no radicle, do you include a 0 for radicle length when calculating the average or do you leave it out of the calculation all together? Thanks much for your help!

102: We tested the toxicity of bio-degradable laundry detergent on lettuce seeds. The radicals of the plants that germinated were withered and brown, a result that differed from every other experimental substance group. Any insight as to the cause of this result?
103: We performed an experiment in which we tested the effects of PowerGel (basically, liquid electrolytes) on lettuce seed growth. I want to know: are plants able to utilize electrolyte- type fuel in the same ways that people do?
104: In measuring radicale growth length of lettuce seeds in a toxicology lab at GGSE. While handling the tender radicales, I broke many of them in my attempt to measure them. What should I do with these results? Do I try to estimate the length or throw out the results?
105: How does exposure to water cause lettuce seeds to germinate, and why is no light required for growth? Is it because the seed provides the necessary nutrients?
106: In one of my recent teacher education classes, my lab partner and I tested the effect of a toxin (in our experiment the toxin was PowerGel aka liquid electrolytes) on lettuce seed growth, over a 7 day period. In comparing our results to those of the other groups (whose used different toxins), our lettuce seeds that sprouted were much smaller in length than everyone else. Why might have power gel affected the diameter of the lettuce sprouts, been smaller than the rest of our classmates?
107: During a toxicity lab performed at UCSB, we took butter lettuce seeds and used UCSB Lagoon water taken from the North shore (farthest away from Pacific Ocean opening) near the faculty lounge, to see if the seeds would grow. When the water was collected, we noted significant levels of algae and detritus in the water (strong offensive smell). Due to the proximity of our collection location to the Pacific Ocean, there may have been significant levels of salt in our test substance. The contaminated lagoon water poisonous in lettuce seeds and inhibited germination and growth of the radical in seeds treated with concentrations 10% and above with the lagoon water. My question is; what are the chemical components of the water that inhibit growth in the butter lettuce seeds?
108: We recently did a lab on the effects of different substances on the growth of lettuce seeds. Our substance (Trader Joe's "Next-to- Godliness Liquid Laundry Detergent") allowed similar amounts of growth, yet it was the only substance in the study where the roots were all brown. Why do you think this was?
109: Is there any evidence that low concentrations (0.001%-1%) of a sugar source on a growth medium might enhance seed growth, rather than inhibit it? We did an experiment where we plated low concentrations of a fruit juice and tried to grow lettuce seeds. The higher concentrations killed them, but in the lower concentrations, there was some growth, but less than for the control (distilled water). To restate: Does an absorbable sugar source help growth of seeds

The theory goes that mutation is the raw material for evolution. Existing sequences of DNA, some of which codes for functional proteins, other sections dont, have random changes in their nucleotide sequence over time, that may persist and dawn reproductive advantage onto carriers of that gene.

I know that changes in the nucleotide sequences of the same gene have been observed across species, like in the genes that code for polypeptides in cytochrome C and hemoglobin. Based on this evidence a sort of evolutionary time line can be developed to show how far back organisms diverged from a common ancestor by comparing the numbers of differences in nucleotide sequence.

In the study of genomes thus far, is there any evidence that suggests a related sequence of nucleotides that result in different functional proteins? Not all organisms have the same proteins, so wouldnt we expect to find that when we find a novel protein on the evolutionary tree, that the nucleotide sequence that codes for that protein would be analogous or similar to a the sequence for a different functional protein? I havent come across anything on this front and was wondering what the experts know. Thanks and I hope you have lots to be thankful for! Sincerely, Bret Klopfenstein Ventura HS

I'm asking for help with the assistance of my teacher. I'm doing a science fair and research project on the golden ratio in nature. I'm interested in mathematics and finding relationships between things I can measure in the real world.

I've been doing research on the golden ratio and I've found that the information is either too general or too advanced. I think there may be two ways you could help me:

1. I would like some help finding material that could help inform me appropriately (beyond the junior high level, but easier than graduate school) for my mathematical research.

2. Is it possible that there might be someone on campus willing to mentor me?

Teacher's note: This student is one of the brightest girls I've seen! Worth nurturing/Mentoring!!!!


I am doing a project on DNA sequence and on how changes in the sequence cause disorders. For example, cystic fibrosis is caused by a recessive allele. When you look at that string of DNA you can see there are three DNA bases missing. Here are my questions I need answered:

1) What kind of technology you would use when looking for the DNA impurities?

2) In the sequences is it easy to point out the mistakes or are they hard to see?

3) Is a specific name for this action or do I just call it DNA sequencing?

4) Is it possible to replace the mistakes with the correct sequence?

--Thank you

This is a sealed room to only grow plants. I will be introducing C02 @ 1500 PPM to maximize growth, and I do not want to ventilate the room and loose my C02. So, I will have to introduce oxygen to the room. I know that we have about 21% in our atmosphere but I do not know what the Oxygen level needs to be in order to grow healthy plants?

This is the last thing I will need to know to finish my set up, everything else is in place and ready for plants.

I hope that you can find an answer for me as I have not been very successful on my own.

Thank you

Hi! For my science fair project I'm doing an experimenting plant gravitropism, by growing three bean plants upside down, and three right side up. I have some questions for you to please answer:

1. For the upside down bean plants, I just put the seed in normally, however it still grew upwards. The roots came out of the bottom of the fiber seed starter pots, and the shoots burst through the pot and grew upwards! I expected the plant grow down, and then curve up.
2. What would have happened if the pot was clay? Would the shoot have turned around when it reached the top, and grow out the bottom?
3. What should I have done if I do the experiment again?
4. I know about negative and positive geotropism, and I now feel bad for having expected it to grow down and then up! Thanks so much!- Natasha


My science experiment is about plants adjusting to their environment to reach light.I have one plant in each of my three boxes. In each box there is a cut out hole and the hole is in a different area, in which the plant must adapt. My first question is:

1. I have planted my sweet peas but it takes them around 10 days to sprout. When do I record in my data table?

2. How should I record its growth when it hasn't even sprouted ?

3. Once it sprouts, should I record its growth as day 1?

Then, should I record every 2 day or 3 days?

Thank you very, much for your help !

I read an article attempting to explain why viruses attack cells. The argument mentioned by the author hinges around the idea that a virus is genetically programmed to attack cells. We already know that. What is missing is how this viral genetic code was written in the first place. This is not a philosophical question!

The point is as follows: evolution is an ongoing biological process and different life forms are different form one another. Having said that, it is not clear how the genetic make-up of a virus can be designed in order to successfully attack cells. Consider the differences between a bacteriophage and the Human Immunodeficiency Virus (HIV). Clearly, they have different structural properties that allow them to successfully invade the corresponding targets. Why? How did it happen? What are the fundamental mechanisms underlying viruses, i.e., design and build a virus that will be able to infect the following cell? Scientific answers are required to tackle these hard questions.

I 'm aware when plants are not in the light they respire just as we do. I also know the products of photosynthesis are sugar and oxygen. My questions are:
How do plants get energy when they are in the light if photosynthesis produces no ATP? Do plants always have to respire with the sugar produced from photosynthesis? Or is there some energy made from photosynthesis and if so in what form?

415: Batrachotoxins, or frog toxins that are found in the genus phyllobates of poison dart frogs, have been identified in the diet of the frogs rather than being self-synthesized. I was wondering since the discovery that beetles from the family merylidae were known to contain the batrachotoxin ingredients, how did the beetles obtain the necessary parts for batrachotoxin synthesis, since these beetles cannot make the toxin themselves? Has a plant source been identified that makes the alkaloids for beetles to consume, and if so, how do plants make batrachotoxin in the first place? Thank you.

Hi sorry to bother you, I am contacting you after reading this article on your site:

click here

I was hoping that you would able to answer a few quick questions I have about a project I am thinking about doing for the BT young scientist.

1) Do different spectra of light effect the growth of plants differently? (Ignoring green)

2) Do specific combinations of light i.e. red, yellow and blue of an equal intensity to solar light effect plants' growth?

3)Does the effectiveness of the light on photosynthesis vary throughout the day? If so do different spectra affect this?

The above questions are to aid in setting a baseline for experiments, as I haven't been able to find any definitive proof online.

505: We are in 1st grade. We are doing an experiment. We are growing rye grass and alfalfa in the dark without any sunlight. Our classroom has no idea how it is growing. It is growing faster than the grass in the window. The grass getting sunlight is a darker green, and the one in the dark is a very light green, but it is taller. How come it is growing without sunlight? We are going to keep watering it and keep it in the dark to see what happens. Will it keep growing? Please write back or come visit us in room 8. We have lots of other stuff growing too, like a sweet potato. Thank you! P.S. Daphne helped type.

610: Is it possible that Earth originally developed prokaryotes as a form of collecting ingredients from its surface and atmosphere in order to re-utilize them for preservation?

I wonder this because how else could inanimate material come alive, and I once read that the Earth is alive itself, leading me to believe that Earth could have been the first producer. I still wonder how the Earth would have come alive itself, but I theorize the electrical forces of atoms and specific molecules pulling or pushing themselves together or apart, as well as the natural movement of heated atoms, along with the already present forces of Earth's spin and movement produced by the big bang could have caused the inanimate Earth to begin "come alive." The original moving up of iron (or whatever element was attracted to another) from inside Earth could have led to a chain of reactions that led to more chains of reactions, and so forth, so that a never-ending push and pull were then created via the original electrical attractions. I realize this is a complex idea and a far-fetched question, but I found your website and thought I'd ask. Thanks either way!

I am doing a project on the effects of different artificial light colors on plant photosynthesis. I was going to test the theory by placing the plant in front of each color light, by buying different color light bulbs, either being blue, red or green, etc.

However I do not know if that is right as I have read in certain sites, which say that to test this theory, one needs to place the plant in front of light sources such as Ultra-violet light, Infra-red Light, or other light sources in the spectrum.

I was hoping you could answer my question as to which theory is correct, or if there are any mistakes in the theory,

We are doing a science fair experiment that involves Music and Plants. We visited your website and found the information useful but had a few questions. We were wondering if you thought that a certain genre of music would affect a plant’s growth more than another genre. The hypothesis for our experiment is, “If jazz, rock, and classical music are played for four hours every day for the first two weeks of a pinto bean plant’s growth, then the jazz music will most positively affect the height of the growth of the plant.” We would like you thoughts on our hypothesis and any suggestions you may have. Thank you for taking the time to read this email and we hope to hear from you soon.
