Answer: b. False

Many mammals rests for a large proportion of the 24 hour. The rest period usually extent during hibernation. The marine mammals tend to rest or sleep with only one hemisphere is kept at rest. It allows them to keep one eye open this allows them to stay alert against the predators. But the terrestrial or land mammals when take rest both the hemispheres of the brain sleep.

On the basis of the above description, most land mammals have the ability to rest one hemisphere of their brains at a time is false.

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18
iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>

In a duplication, a person has more than two alleles for a certain trait. crossing-over between sister chromatids has occurred t
Leni [432]

The right answer is a person has more than two alleles for a certain trait.

Duplication is a genetic mutation characterized by the doubling of genetic material on a chromosome. There are several mechanisms that result in the duplication of either a large chromosomal portion, a gene, or a nucleotide sequence.

The skull size of each species! 

It's the size of the skull specifically the jaw bones, that can help determine relationships of two hominid species.

Hope this helps!
