Firstly we have to know what is meiosis.
Meiosis is the cell division process by which a diploid (2n) mother cell divided twice to produce four haploid (n) daughter cells.
Diploid cells have paired chromosomes. For example, in human, the diploid cells contain 23 paired chromosomes, i.e., 46 chromosomes.
Haploid cells do not have paired chromosomes. In human, the haploid cells contain 23 chromosomes only.
We know, chromosomes contain DNA (Deoxyribonucleic Acid).
So, if the chromosome number is half in case of haploid cells, then obviously, they have half as much DNA.
So, the correct option is 2. They have half as much DNA.

Answer:

2. They have half as much DNA.

Hope you could understand.

If you have any query, feel free to ask.

What is a natural, nonspecific immune response, but it is part of the body's second line of defense?

Strike441 [17]

The adaptive immune response is the second line of defense against non-self pathogens. Adaptive immunity, also known as acquired immunity or specific immunity, is found only in vertebrates.

<h3>What is second line of defense?</h3>

Nonspecific resistance, which destroys invaders without targeting specific individuals, is the second line of defense: phagocytic cells ingest and destroy all microbes that enter body tissues.

The adaptive immune response is the body's second line of defense against non-self pathogens. Adaptive immunity, also known as acquired immunity or specific immunity, is found only in vertebrates.

Thus, adaptive immune system is a natural, nonspecific immune response, but it is part of the body's second line of defense.

Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy.

Nastasia [14]

Law of thermodynamics states that matter and energy cannot be destroyed or created, but can be converted from one form to another. A balanced equation ensures that this basic principle is observed.

On the left-hand side of the equation (the reactants), there are 2 Nitrogen moles and 8 Hydrogen moles. After the reaction, the molecules are rearranged. Nonetheless, the moles of Nitrogen and Hydrogen in the products remain the same.
