Correct answer: D
A pollen is where male gametes are produced and so the number of chromosomes, as we are talking about gametes, is n. This means that the grain of pollen will only have a copy of each gene, and therefore only one allele for each gene - one S, and one T or t. So, the possible combinations are ST and St.

<u>Answer</u>: A heritable trait can be changed from one generation to another.
<u>Explanation</u>:
- The concept of <em>descent with modification</em> was given by Darwin which simply states that the traits are passed on from the parents to the offsprings.
- The traits that can be passed on are known as <em>heritable traits</em>.
- These traits are passed on with the help of the genes.
- So this passing on of traits explains the term <em>descent</em> in this concept. However, there are always chances that these heritable traits can be changed due to environmental factors or due to the process of recombination and thus the term <em>modification</em>.
- So <em>descent with modification</em> means that a<em> heritable trait is passed from parents to offspring but it can be changed from one generation to another.</em>

Density and distribution of stars are directly affected when the change occur in the size of the circle.
<h3>Effect on density </h3>
The density and distribution of "stars" changed as the circle gets larger because when the circle gets larger, its volume increase which results in the decrease in the density. The distribution of stars also changed due to more space or volume present in the medium.
<h3>Distribution</h3>
If the universe is more condensed, then the stars are more closer together but when the universe is more expand then the stars are present farther away from each other so we can conclude that density and distribution of stars are directly affected when the change occur in the size of the circle.
