Answer 1

If an organism has a diploid number of 60, then its haploid number is 30. Thus, C is the correct option.

The term "diploid" describes how many complete sets of chromosomes there are in each cell of an organism: diploid cells have two entire sets(or 2n number). On the other hand, haploid organisms only have one complete set of chromosomes (or n number).

So if diploid number is 60, i.e., 2n=60, then the haploid number is

n=[tex]\frac{60}{2}[/tex] ⇒ n= 30.

Answer 2

If an organism has a diploid number of 60, its haploid number would be 30. Therefore, the correct statement is option C.

What is diploid number?

The diploid number is the total number of chromosomes present in a cell equal to the number of chromosomes present in each homologous pair. If  the organism has 60 diploid number, then 30 chromosomes are inherited from each parent.

The haploid number to the number of chromosomes present in a gamete of the organism. Gametes only contain one set of chromosomes, therefore, the haploid number will be half of the diploid number, i.e. 30.

The haploid number is half the diploid number because during meiosis, the number of chromosomes is reduced by half. The haploid number is important because it determines the number of chromosomes in the offspring of sexual reproduction.

Therefore, if an organism has a diploid number of 60, its haploid number would be 30.

What does the Punnett square show?

Your question is incomplete but I will tell you something about how the  Punnett square  works.

A Punnett square is a graphical representation of the possible genetic outcomes of a cross or mating between two individuals. It is used in genetics to predict the frequency of different traits in the offspring produced from a genetic cross.

The Punnett square is set up as a grid, with one parent's alleles along the top and the other parent's alleles along the side. The alleles from each parent are combined in each box of the grid to represent the possible genetic outcome for a single offspring. The frequency of each outcome can be determined by counting the number of times that each combination appears in the grid.

The addition of yeast into bread dough makes it raised by increasing its volume, and the growth of fungus takes place on bread slide when it is left for a longer time in moisture. A researcher took samples from the dough of bread on slide A, and from old bread on slide B. The researcher observed the growth of these organisms under the microscope. What type of asexual reproduction might have been observed by the researcher on both the slides?

Answers

Answer:

The correct answer is 'Saccharomyces cerevisiae'.

Explanation:

Bread dough is made using yeast. As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. It increases as a result. The expansion of carbon dioxide during baking allows the bread to rise higher. Baker's yeast, commonly known as Saccharomyces cerevisiae, is used to make many different bakery goods in addition to bread.

It is employed in the fermentation process, which yeast performs on the sugar and starch in the flour. Fermentation transforms the starch into alcohol and carbon dioxide.

After baking, the carbon dioxide in the dough gives the bread its softness and fluffy texture. It also causes the dough to rise.
