Answer:

Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.

Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.

However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant all

Bogdan [553]

<h2>Question 1.</h2><h2>Answer:</h2>

The correct answer is option D which is 100%.

<h3>Explanation:</h3>

According to the description of Punnett square given in the question, there will be there will be two types of genotype and one type of phenotype which is yellow.

YY, homozygous dominant = Yellow Seeds.
Yy, heterozygous = Yellow Seeds
So the progeny will be 100% of yellow seeds.

Punnett square is also attached.

<h2>Question No.2.</h2><h2>Answer:</h2>

The correct answer is the option A which predicts the genotypic and phenotypic probabilities of possible.

<h3>Explanation:</h3>

<u><em>Punnett square is a way to determine the probable genotype of expected offspring by the genotypes of father and mother devised by Punnett.</em></u>

In this method, A square shaped table is constructed and the alleles of the gene of father/male are written on the top of tables, on the column.
The alleles of the mother are written in horizontal to square, in front of rows.
So the genotypes in the square box by multiplying row and column alleles will be expected genotype of an offspring.
The example is attached below.

<h2>Question no. 3.</h2><h2>Answer:</h2>

The correct answer is option C which is 1 = TT; 2 = Tt; 3 = Tt; 4 = tt .

<h3>Explanation:</h3>

The Punnett square is made by the description given in the question.

There are total 4 boxes. In box number 1 which is on top left genotype is TT and in box 2 which is on top right genotype is Tt. In box 3, the genotype is Tt and in box 4, the genotype is tt.

So according to the given Punnett square information in option C is correct one.

One of the roles of plasma membrane proteins is to____. see section 6.4 ( page 131) .

fenix001 [56]

One of the roles of the plasma membrane protein is to FACILITATE THE PASSAGE OF SOME SELECTED MOLECULES WHICH COULD NOT OTHERWISE CROSS THE LIPID BILAYERS.
One of the function of the proteins that are embedded within the phospholipid bilayers of the cell membrane is to act as carriers to some substances which have to enter the cells but which can not enter the cells on their own.
