Answer:

Saliva also help in moistens the food for easy chewing and swallowing. ... digestion of food starts in mouth. the saliva contains an enzyme called salivary amylase which acts on the carbohydrates to break the food into smaller particles and also to wet the food so that it would easy to chew and engulf.

Hope This helps.

Mathematically the it would be D 

but scientifically since eventually food and resources will start becoming scarce it would be A then as the ecosystem recovers it goes back to D <span />

A biologist analyzes the DNA sequences of one gene in three different primates . The biologist finds that primates A and B have
Nataly_w [17]

The question is incomplete as it does not have the option which are:

  • primates A and B are more closely related to each other than either is to primate C.
  • all three primates appeared on Earth at about the same time.
  • either primate A or primate B must be a direct ancestor of primate C.
  • primate C must have been the ancestor of both primate A and primate B.

Answer:

Primates A and B are more closely related to each other than either is to primate C.

Explanation:

In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.

The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.

Thus, the selected option is the correct answer.

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d
KengaRu [80]

Answer:

a)  Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

<h2>                                      (<u>a)</u> </h2>

Mating has occured between a normal colored mice whose genotype is C_,V_  and normal white  mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

<h2>                                      (b)</h2>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

<h2>                                      (<u>c)</u>  </h2>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>
