Answer:
2 chromosomes
Explanation:
The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.
Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.
The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.
Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.
This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
Proteins. they are a string of amino acids
Answer:
I do not know if I am entirely right, so please tell me if I am wrong.
1. Sulfur Dioxide
2. Condensation of chemicals in the atmosphere
3. Acid Precipitation
4. Acidic Water
Explanation:
Sulfur Dioxide is coming out of the factory. (A).
The chemicals are condensation in the clouds (B).
Its raining acid rain(C)
Acidic Water because rain goes everywhere(D)
It would affect marine life BUT it does not say it affects marine life on the tile.
Ecology because it explains plants and animals
Answer:
<h2><em><u>True </u></em></h2>
Explanation:
As,
DNA needs to be duplicated before the cell divides so that both new cells have the same amount of DNA
