In gorillas, the ability to roll the tongue is under the control of 1 gene. The R allele, which confers tongue-rolling ability,
aalyn [17]

Answer:

0.4550

Explanation:

In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.

In this case, there is Hardy Weinberg Equilibrium, so the following will be true:

p^{2}+2pq+q^{2}=1

Where:

p^{2}= frequency of RR

2pq= frequency of Rr

q^{2}= frequency of rr

The question is what is the frequency of heterozygotes, or, what is the value of 2pq.

We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.

In other words:

p^{2}+2pq=0.575

So, it is possible to find q^{2}:

q^{2}= 1-2pq-p^{2}  \\q^{2}=1-(0.575)\\q^{2}=0.425

Now, there are two alleles in the population, so the following will be true:

p+q=1

It is possible to find q  (the frequency of allele r) and p (the frequency of allele p):

q=\sqrt{q^{2} }\\ q=\sqrt{0.425} \\q=0.652

Therefore:

p=1-q\\p=1-0.652\\p=0.348

Now, the frequency of heterozygotes or 2pq is:

2pq=2*0.652*0.348\\2pq=0.45

All the things that we can sense (sights, sounds, smells, temperature, taste, and pressure) have their origins in the ________ n
Eva8 [605]
All the things that we can sense have their origins in the PERIPHERAL NERVOUS SYSTEM.
The peripheral nervous system is made up of all the nerves that are located outside the spinal cord. These nerves transport information to and from the central nervous system. The sensory cells are involved in carrying information from the peripheral nervous system to the central nervous system. The sensory cells include the cells that are responsible for sight, sound, smell, taste and pressure.<span />

Aside absorbing water and nutrients, what other functions do the roots serve?
AfilCa [17]
<span>Aside from absorbing water and nutrients in the ground, roots are also the very support of a tree. It supports bigger trees to stand and stay steady against heavy rains and strong winds. Roots are also capable of absorbing water that may cause flood in the area, and support slopes that may result to landslides. Roots are very important because it lessen the chances of soil erosion in a certain place. Roots can also be used for plant vegetations.</span>

Camel humps are an adaptation for _______.. a.. storing water. b.. regulating body heat. c.. carrying riders. d.. all of the abo
Fofino [41]

The correct answer is:

b regulating body heat.

Explanation:

Camels have humps on their backs as rooms to store fat. It is this fact that they live off when food and liquid are scarce. A well-fed camel in good shape has a firm, upright hump. After a long, exhausting wilderness journey the corresponding camel will have a hump that does floppy and bent over to one side.e. Concentrating body fat in their humps reduces heat-trapping.
