Normal And Mid-Ocean

Explanation:

Just did it and it was right :)

Based on the magnetism on the seafloor, the sections with reversed polarity on the right side are shown as the grey areas in the diagram attached.

Magnetism on the seafloor

Leads to ridges having reversed and normal polarity.These ridges often alternate.

The first ridge to the right will have a normal polarity. The next ridge will be reversed and this trend will then repeat till the end.

a. What is the diploid number of the species shown in Figure 1?
b. What is the haploid number of the species?

Answers

Answer:

I hope this helps you

Explanation:

1)This number is abbreviated as 2n where n stands for the number of chromosomes. For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).

2)Under normal conditions, the haploid number is exactly half the total number of chromosomes present in the organism's somatic cells. For diploid organisms, the monoploid number and haploid number are equal; in humans, both are equal to 23.

The diploid number is 2n no. of chromosomes and thus it is diploid instead of haploid.

This variety is abbreviated as 2n wherein n stands for the variety of chromosomes. For people, the diploid chromosome variety equation is 2n = 46 due to the fact that people have units of 23 chromosomes (22 units of autosomal or non-intercourse chromosomes and one set of chromosomes).Under everyday conditions, the haploid variety is precisely 1/2 of the entire variety of chromosomes gift withinside the organism's somatic cells. For diploid organisms, the monoploid variety and haploid variety are identical; in people, each is identical to 23.

What are chromosomes?

Chromosomes are thread-like systems placed in the nucleus of animal and plant cells. Each chromosome is made from protein and a single molecule of deoxyribonucleic acid (DNA).

Thus it is clear that the diploid and haploid number of the species depends on the number of chromosomes.
