Hey I'm Rachael, I love playing sports, especially field hockey, listening to music, chilling with my friends, and doing anything creative.
I love going to the beach and someday want to live in California. :]]
So far,my favorite thing
was trying to create the best shape for a cell to diffuse. It aloud me to think of creative ways to shape the cell so it could have a large surface area,but a low volume. Unfortunately, my group did not find the most efficient cell, but we were able to figure out how to make it better.

Apply creativity to work
I will provide colorful and interesting pictures to my posts that I took myself

I will make voice threads
I provided a picture of fraternal twins to my post about Twins that I took myself.
I provided a video that I made myself about how fraternal twins are made.
I provided a video that I made myself about how identical twins are made.
Here is my interview with a biologist student,
James J. Young
: Do identical twins share a more similar IQ then fraternal twins?
: Yes, identical twins generally have more similar IQs than fraternal twins.
The heritability of IQ is 40-80%. Heritability is a measure of the
amount of variance of a trait in a group that is determined by
genetics as opposed to other factors. You can think of it as the
amount that genetics pushes an individual away from the mean of the
(IT% - FT%)*2 = Heritability
Heritability is calculated by subtracting the percentage of identical
twins with the same IQs (IT%) from the percentage of fraternal twins
with the same IQs (FT%) and multiplying by two. This is because
identical twins are 100% alike in their genes whereas fraternal twins
are only 50%. We assume that the extra 50% of genetic-relatedness
manifests in more similar IQ, and we can calculate its amount using
Because heritability is positive — not zero — for IQ, identical
twins have on the whole more similar IQs that fraternal twins.
(Note that whether IQ is primarily genetic or determined by the
environment is still a very controversial subject among scientists.
Even though identical twins have more similar IQs than fraternal
twins, high IQ probably also has strong environmental causes.)
: Are there any cases in twins where one has been normal why the other one is mentally disabled?
: Yes. If the heritability of IQ were 100%, then the only thing that
determined IQ would be genetics, and difference among identical twins
would not be possible. But it isn’t. This means that environment
plays part of the role.
There are certainly cases where identical twins have had markedly
different IQs, though these cases are rare. In most of them, I would
say it happened because of a developmental problem in the womb rather
than because of a genetic cause. For example, it would be impossible
for one identical twin to have Down’s syndrome while the other did not
because Down’s syndrome has a genetic cause. But mental retardation
-using the medical definition of IQ <70 -- has a lot of
environmental causes too -- such as inadequate nutrition in and
outside the womb.
If you expand your definition of mentally disabled, cases where one
identical twin has
or ADHD or
other does not are quite common.
Here is my interview with marine biologist,
: What makes this fish so unique?
: In a whole lot of ways this fish is unlike any other that we know: it is covered with a wild swirl of tan and peach colored, zebra-like stripes, and behaves in ways that have never been described before. It has a flattened face with eyes directed forward. It doesn't swim like other fishes, but hops along the bottom, propelled by jets of water that it squirts out of it's tiny gill openings. Each time it strikes the seafloor it uses its fins to push off. It looks like inflated rubber balls bouncing along.
: How does it differ from other fish of its kind?
: It is a kind of anglerfish, a large group of about 320 species that have a fishing apparatus attached to their snout or forehead. They sit out in the open on the seafloor or
, often adapting their coloring so their bodies are camouflaged, but the lure is meant to be noticed so the anglerfish waves and wiggles the lure to attract prey. But, this crazy new species has no lure at all, so it must find food in some other way. Unfortunately we don't know how it does it.
: Do you know where and how this fish evolved from?
: It has evolved from a group of large, flattened, shallow water anglerfishes called monkfishes or goosefishes, which is common on the East Coast of the U.S. and which is sometimes available in the market. It is a very tasty fish! You can see pictures of these monkfishes, as well as pictures of many other types of anglerfishes on my "
