Why would it be hard to find the ideal light intensity if the temperature were very hot or cold?

1 answer:

5 0

Under extreme temperatures Enzymes become inactivated or denatured. due to this reason there will be no change in Photosynthesis despite a change in Light intensity.

<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.
