Mitosis is the process of cell division, where one parent cell divides to produce two genetically identical daughter cells. This process is vital in growth and tissue repair.
The reason that tissue from the fetal stage is helpful in studying mitosis is because mitosis is continuously and rapidly occurring in this phase of life in humans. The high rate of mitosis is due to the need for the fetus to grow rapidly and develop the necessary parts for it to be born.
Answer:
Stabilizing selection
Explanation:
The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.
During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.
In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.
Thus, Stabilizing selection is correct.
Answer:
It results in the production of new combinations of alleles due to which offspring can have different characters than both the parents.
In meiosis, the genes are randomly segregated and the alleles of genes are independently assorted to produce haploid gametes.
When the gametes of male and female fuses, they form the zygote with a unique or new combination of alleles as compared to that of parents.
It increases the genetic variations in the population.
A compound is always a substance because it's made out of two or more atoms bonded together. Now a substance isn't always a compound because it takes two or more elements to create a compound in a chemical reaction, ans substances can contain only one element. In other words a substance can be constructed of one type of atom. Some substances that aren't compounds are: gold and baking soda.
