Jillian angrily throws her engagement ring straight up from the roof of a building, a height h above the ground with an initial speed of v, For the motion from her hand to the ground, what is the magnitude of the average velocity of the ring? What is the direction of the average velocity of the ring? For the motion from her hand to the ground, what is the magnitude of the average acceleration of the ring? What is the direction of the average acceleration of the ring? In how many seconds after being thrown does the ring strike the ground? What is the speed of the ring just before it strikes the ground?

BIOLOGY 1108 EVOLUTION AND POPULATION GENETICS

Variations on the ability to taste PTC have no obvious survival value, and yet there is ethnic variation in allele frequencies between different groups. For instance, 63% of Arabs are tasters for PTC, whereas 63% of native Americans can't taste it. At least one condition of the Hardy-Weinberg Theory was not met respect to the gene in the world populations.

1. How do you think this ethhnic variation came about?

2. How could this variation in allele frequency be associated with survival potential of the ability to detect a bitter taste?

3. Assuming there was no selective advantage for this traitt, what other factor might account for the ethnic differences?

This is my homework. Its not for a grade for right or wrong but for effort and I am having a little trouble with this. Does anyone know about this stuff if so please help me. Even though the grade is for effort I still want to understand it so I'll do good on the test. Thank you

The Red Planet is about to be spectacular!

This month and next, Earth is catching up with Mars in an encounter that
will culminate in the closest approach between the two planets in
recorded history. The next time Mars may come this close is
in 2287. Due to the way Jupiter's gravity tugs on
Mars and perturbs its orbit, astronomers can only be
certain that Mars has not come this close to Earth
in the Last 5,000 years, but it may be as long as
60,000 years before it happens again.

The encounter will culminate on August 27th when
Mars comes to within 34,649,589 miles of Earth and
will be (next to the moon) the brightest object in
the night sky. It will attain a magnitude of -2.9
and will appear 25.11 arc seconds wide. At a modest
75-power magnification.

If you already knew, did you get to see it????????? I just think it is amazing news! If it was for real. Pls. tell me!!!!!!!!!!!!!

READ
i think everyone been biased against pluto,
everybody say pluto's the 'bad' one, crossing into Neptune's orbit, thus making itself a dwarf
well from another point of view, we could also said Neptune's the one to be accused because it crossed over Pluto's orbit.
thus it only would make sense that Neptune be demoted because it hasnt 'clear the neighborhood' aorund it


what i'm trying to say? the new definition is pathetic, laughable and just purely stupid with the 'clear the neighborhood' clause

It's pretty obvious that Europeans are the most diverse. Europeans are the only race that can have blue and green eyes, blonde and red hair. If Africans have any hair or eye color besides black/brown it is only due to European admixture. Plus, I have seen plenty of African Americans and they all have similar nose, mouth, and eye shape. Europeans have dozens of different nose shapes, mouth shapes, eye shapes, and facial structures. It's just to obvious to even argue about.

Wasn't quite sure if this was the right place to put this question, but I think I'm in the right ballpark, at least.

Now, the answer to this question doesn't have to be that realistic (but let's not involve, say, magic or fairies, 'kay?), but if you fell full-distance from an airplane onto some sort of surface, what kind of padding (and how much of it) would you have to have on the ground in order to survive? Or is survival possible at all? I ask this because I know that even relatively non-solid surfaces (such as sand or water) would have no cushioning effect whatsoever--from that height, there's little difference between those and concrete.

Thanks!
