increase in estrogen causes the anterior
pituitary to release a surge of luteinizing
hormone, which releases the egg (ovulation). I
also read on-line that "the pill" contains
hormones, estrogen and progesterone, and these
stop ovulation, but keep the rest of the cycle
going. If estrogen is what causes ovulation, how
can the estrogen in the pill stop ovulation?

in a 7th grade Life Science class. I recently
assigned disease reports to students and some of
the assigned diseases are caused by prions. I'm
certainly not expecting them to know all of the
details about prions, but I figured that I should
know about them in case I have questions. I've
looked up information on the Internet and read
the prior prion question that is posted on
Science Line, but I still just don't understand
how prions work. How are they infectious? How
do they change other proteins? Are they anything
like viruses, or more like regular old protiens.
I've also seen information about them being
caused by humans' own genetics, so I just want to
know, basically, what they are and what they do.

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? If it does this, is this the reason we could say that hand gel is effective in killing viruses that may get on your hand?

In science, I am starting a Science Fair project and I have a few questions that need to be answered for guidance and advice. My project is: How do the size, color and amount of time to see an image affect a person's image memory?
1) What do you suggest I should do to test the affects of different sizes, colors and amount of time to look at an image on a person's image memory?
2) How would I measure these effects?
3) What do you suggest I should do to record my data?
4) Does level of intelligence and age affect a person's image memory? How?
5) Based on your experiences, how do you think image memory affects a person or a community?

We are studying protozoa and have some
questions about the shape of ameobas. In the

the bacteria... does that mean that there is no

pseudopods 3-dimentional? We don't know, since
we've only seen them on slides, flattened under
cover slips - what shape are ameobas when they
float freely in the water?

|497: ||In Psychology, it is a well known fact that one can change oneself through positive self- affirmation & visualization .It is believed that the self-affirmations to the subconscious mind are best done in an already achieved mode. For example, a student who is weak in mathematics and wish to improve on it should say the self- affirmations as I am excellent at mathematics & also visualize himself as ALREADY being good at Math repeatedly. Or a person who is a coward could reprogram his mind by saying to himself, I am brave, etc. This is so that the subconscious mind is set with the positive intended goal and thus will program the whole body with the message. But the question is that such self-affirmation is not the truth (or not the truth yet). When he is telling himself that he is ALREADY being good at Math, he is actually lying to himself. So, would it better to say,I am getting better and better at Math rather than I am excellent at Math?

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
(orangutans, chimpanzees, gorillas, gibbons, and
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
Any help or references to resources on the
subject would be greatly appreciated! Thanks!

I am in 8th grade and I\'m starting to work on
science fair project. The question for my
How does sight affects taste?
I will test that by having 3 equal amounts of
drinks in clear cups. One will be cherry, one
be grape and one will be lemon/lime. The
volunteers will first taste each drink and try to
guess the flavors. Next, I will blindfold the
volunteers and have them guess again. Then I will
add food coloring to the drinks to make the
look like grape, lemon/lime look like orange and
grape look like root beer or cocoa cola. The
volunteers will then test each drink and tell me
what they think each flavor is. My hypothesis is
that on the control and blindfolded test, most
people will guess correctly. On the incorrect
colored test, I think people will guess the
to be grape, the lemon/lime to be orange and the
grape to be coca cola.
a. Do you think that the procedures should
differently in order to answer my question (How
does sight affects taste)?
b. Do you think the colors of each flavor
difference, or should I change them?
c. Do you think my hypothesis is correct?
d. Is there anything important that I need
before I start conducting the experiment?
e. How many volunteers do you think I
to make the experiment reliable?
f. How do you think I should graph this

deal with, and should I make it to just one

effects taste that you think is important to
conduct this experiment?

Dear UCSB Researchers, I am an 8th grade
student hoping to research methods of resisting
bordetella pertussis disease. I was thinking that
if there was a vaccine that would increase the
growth of cilia on our ciliated epithelial cells
in our respiratory system, then we would be more
protected from whooping cough. Would you think
this could be a good hypothesis? "If our
epithelial cells in our respiratory system produce
continuous amounts of cilia, then our bodies will
be more protected from bordetella pertussis." I
see two possible questions to study:
1. Is there a chemical that can grow more cilia
on lung cells?
2. What can I use as a safe substitute that is
just like bordetella pertussis?
I think that pertussis is too dangerous to use
as a bacterium, so what would you recommend as a
substitute? Also, how could I grow these cells at
my home without a lab? Is there a way I can grow
more cilia on cells? How could I actually measure
how many cilia are present (would I take a picture
and count)? Thank you! From an 8th grade

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?

In the beginning of this experiment, I
hypothesized that Classical music would lower the
heart rate and blood pressure by releasing greater
amounts of Serotonin into the bloodstream. I also
hypothesized that Rap, or any high-temped music,
raises norepinephrine levels.
My studies have shown that this is true, but
not in every case. 50% of my subjects’ blood
pressure rose while listening to rap, but the
other half did not, instead staying neutral e or
even lowering. 75% of the subjects’ blood pressure
decreased with Classical music, but the effects
were not as drastic. 50% of the subjects enjoyed
rap, which is probably the cause of the lowered
blood pressure. 50% enjoyed classical music, or
knew the song, which is why their blood pressure
lowered. The heart rates of all the subjects made
no pattern during this experiment, except after
the classical music was played. In conclusion to
my experiment, I realized that whichever genre of
music you enjoy lowers the blood pressure, not due
to the rhythm.
Can you relate to my conclusion? Do you think it
is accurate? Thank you so much!

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
