Hi,
I’m pretty sure the muscle moves the chicken wing. I had to do a lab and this is what I was told.
Answer:
the <u><em>cell membrane</em></u> is an extremely pliable structure composed primarily of back -to- back phospholipids (a "bilayer")
Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.
Your answer is the peripheral proteins. Its on the inner or outer surface of the phospholipid bilayer, but not embedded in its hydrophobic core.
D. The umbilicus is caudal to the chin
The terms caudal and inferior are synonymous, meaning "away from the head end or toward the lower part of a structure or the body; below." The umbilicus is caudal (inferior) to the chin.
