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.
When cells reach their size limitations one of two things will happen: they will either stop growing and split into two separate cells. Cell division can be both good and bad.
Answer:
1. Option A
2. 56
Explanation:
1.
Option A
Option A is not a valid answer for this question as it is given that out of eight rats only two rats are untrained. Thus, an output which shows more that two untrained rats i.s UUTTU is a wrong answer
2.
Thus , there are 56 outcomes possible for this experiment
I would think it would kill it completely
Immigration followed by competition
I hope this right, if its not, sorry =)
