|41: ||Our AP Bio class is studying taxonomy and how different species are grouped together. Our textbook introduces the concept of grouping everything into three domains, but it's a few years old and implies that at the time of writing it's not sure how things will end up being classified. We were wondering if there are any "kingdoms" under the domains of Archaea or Bacteria. Also, under the Eukarya domain, in addition to the kingdoms of Animalia, Plantae, and Fungi, it has several "candidate" kingdoms consisting of the other eukaryotes. Are these as yet actual kingdoms? Internet research has been confusing, as different sources list anywhere from 4 to 10 kingdoms under the three domains. Is there an "official" way of classifying things as of yet?

testing what variables change reproduction rates
in bacteria or mice. In this experiment a control
would be normal conditions and the rate of
growth in these conditions. By limiting food or
developing competition / a destructive event, you
can measure how these variables can effect
reproduction. What seems most interesting in this
experiment, though, is what might happen if it
would be applied to mice. It can be tested
whether or not mice would still reproduce if
there was lack of food creating an environment
that cannot support more than the number of mice

room, flitting up near the light. It then flew
down on to my bed. I looked it up in my Insect
Field Guide (Audubon) and at first I was very
disturbed because it resembled a conenose bug. I
read that they bite humans in the night for
blood, and in fact I did have a few bug bites on
my arm a couple of weeks ago which I thought
might have been caused by spiders. I then
searched the internet and found out that it is a
western corsair because it has a very distictive
orange dot on its otherwise black wings. I'm
wondering if this western corsair is dangerous. I
read it has a nasty bite that can be very
painful. I also read that it eats other insects.
But does it suck blood like the conenose bugs?
Please let me know what you think. Thank you very

On a walk that we took in the mountains (about 1000m - 1500m) of the Verdon National Park in France, in February, in several places we saw a clump of what looked like light green leathery shells. They looked a bit like pumpkin seeds or big lentils. They were about 1cm in diameter. Sort of disc shaped. In a clump there may have been 30 or 50 of these "shells", loosely stuck together in a kind of clear slime that looked a bit like saliva. Some of them appeared to be opened that is two halves (upper and lower) of the disc had split away from each other. Often they were lying on gravel in the sun and were not hidden under any vegetation.
I regret that I did not take a photo. I have searched the internet looking for photos of lizards' eggs, as I thought this is what they might be. However I am not at all sure. If you have any wildlife expert who could tell us what these might have been I would be very grateful.

We have one koi and about 14 fish that are
comets or goldfish in a swimming pool converted
to a pond. They are about 5 inches or so long at
about 1 year of age. Very robust and active. Four
of them are basically white. Of the four, two
have some deep orange spots naturally on them. I
just noticed today that the white on the fish is
turning a washed out yellow/orange color. They
were seemingly pure white before. Now fins and
head particularly are turning organish. I'm
worried about their health. One website that
sells koi food says this is due to liver
function. Can that be correct? If so, what do we
change? We are feeding Tetramin and a special

temperature is in the 80's. Full sunlight on the
pool. The pool is about 15,000 gallons with deep
areas at 8' on one end. The water is not
filtered, aerated or treated in any other way and
is very green as my husband is under the
impression that it is a large enough body of
water to not need extra care. We have two water
hyacinth plants in with them. The fish eat the
fish food, algae and bugs that fall into the
water. The comets/goldfish we bought were sold as

they were only a few inches. They are now robust
in girth, about 5 long in the body and very
active. But I wonder what this symptom may mean

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 have read that all viruses have a protein coat that protects their genetic material and some have an envelope of fat that surrounds them. If the virus coat/shell is made up of proteins and /or fat if ethyl alcohol denatures the proteins in a bacterium cell, does it also denature the proteins and/or fat that make up the virus coat?

Hello there I have received a review article titled "Genomics of reproduction in nematodes: prospects for parasite intervention?" by Nisbet, A.J. Cottee, P.A. & Gasser, R.B.
I have an assignment at university for Parasitology.
I have to present a 10 minute powerpoint on the "main points" that this article discusses. I understand that it is reviewing sex-specific molecules, technologies to identify these all in the hope of developing anthelminitcs and control strategies.
However, I am struggling to understand the concepts within the article such as the different technologies used and the differences between gender-specific and gender-enriched etc.
I was hoping that you could help me understand the key points that this article is conveying. Regards

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?

Hello, I am a current intern at Nationwide
Children's Hospital in Columbus Ohio and I am
having some trouble with teaching myself some
cell signaling pathways for microbial
pathogenesis. I taught myself the three
complement pathways to destroy pathogens through
the use of C5bC78 added to around 10-16 C9s to
make a MAC, but I am trying to teach myself the
toll-like receptor pathways and others like
that. I am very much a visual learner but these
pictures that I am getting online are too
complex for me to decipher. Also, the videos
online that I am finding are too simple and I
need to go more into depth. I have a
presentation of what I did in the lab for the
past few months coming up on August 10th and I
need to be as well prepared as I can be because
a scholarship is on the line that I am competing
with other students for and it is vital that I
am well prepared to be as versed as I can be in
the topic of microbial pathogenesis and
immunology. Are there any sites or books
that you would recommend me looking for? I would
really like help here! Thanks so much.

I have a question about the genetic
similarities between the major primate species

bonobos) and humans. A lot of times one hears
about how humans and chimps are the closest to
each other genetically, differing in their
genetic makeup by only a few percent. I´m
wondering though, how close genetically are the
great apes to each other?
For example, how close are chimps to
gorillas, gibbons, or bonobos? Or gorillas to
orangutans, etc.? Do you guys know of any
references comparing the genetic codes of all of
the great apes to humans (from which I could
deduce how similar the great apes are from
themselves)? Or perhaps a direct comparison of
primate genetic codes to each other? I´m mostly
interested in the overall percentage difference
between each species, but I´d love to look at
any additional information as well such as where
their genetic codes differ with regard to each

subject would be greatly appreciated! Thanks!

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?

We find a lot of fossils today and I have heard
it is because there were different events that
caused animals and dinosaurs to die. Why didn't
the fallen bodies of the dead animals just rot?
Why did they turn into fossils if they just fell
down dead? If all of those dead animals that
are fossilized were buried rapidly with water,
etc., (which is needed for the fossilization
process) what caused that to happen with all of
the thousands upon thousands of fossilized
creatures? Was it thousands of small disasters
with water, etc? I'm just confused on that

|840: || Hello! I am teaching 6th-11th grade sciences. I
have a B.S. in science, but only took a year or so
of microbiology in college. Every year we have
students who want to do microbe projects for
science fair. We have good success growing
microbes in petri dishes. As yet, my best method
for measuring microbe growth is to give students a
5mm x 5mm grid which they lay on top of the petri
dish and have them estimate how much of these
boxes are filled with the microbe that has grown.
Then they add up the portions of the boxes or
whole boxes filled by the microbes and arrive at
an mm squared value. One science fair judge asked
about the height of microbe growth. I guess
students could arrive at an estimate of height by
the same method. I have done online searches
which have only yielded dilution methods. We do
not have any specialized equipment for observing
microbes in dilution, nor do I have stains for the
various microbes to show up on a microscope slide.

Eisenhower Middle School in Albuquerque, New
Mexico. I am doing a project in which I have to
use bio mimicry (mimicking nature to solve human
problems) to solve a food system problem. My group
and I would like to solve the problem we have that
so much water is in the world, yet very little of
it is fresh. We know that there have already been
desalination plants invented, but they aren't very
efficient. We were thinking about making a
desalination plant that is based off the salt
glands that can be found in many sea birds. This
may be a more efficient way of taking the salt out
of water. We have been doing much research over
the course of the past week, but many of the
articles and videos that we are trying to read are
too difficult for us to understand. I was
wondering if you could put in simple language the
processes used by the birds to desalinate their
water. Thank You!

Cousteau’s Ocean Futures Society (OFS) located in

through OFS and the subject came up with a student
a while back about the advantage of uric acid
excretion in birds. Here is the question: since
bird embryos must live with their waste in the
egg, isn’t a big evolutionary advantage of
excreting uric acid a reduction in self pollution
of nitrogenous waste in the egg. Since water is
limited and there is no way to get rid of ammonia
or urea, uric acid is logically the best and only
safe way to deal with such waste in the egg.
I’ve looked on line and in some text books and
not been able to find an answer to this question.

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
