Answer:

False, the subjects in experimental and control groups are same. But the control do not undergo any experimental test.  

Explanation:

In a scientific experiment, we take 2 objects for experiment one is an experiment and one is control.  In experiment animal, we apply many tests on it to know the result of the experiment. But in control animals, there is no experiment on it. one keeps it in its normal condition to compare with the experimental animals.

E.g. The thyroxine hormone increases the metamorphosis of a toad.

It is known by comparing the 2 types of tadpole i.e. one having thyroxine injected on it, and other is normal.  

The control is an independent variable which is compared to the experiment variable/animal to know about the effect of the test.

Therefore, the experimental skill is applied to the experimental object not to the control one.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end o
Ilia_Sergeevich [38]

Answer:

20 chromosomes

Explanation:

Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.

In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.

Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
