Answer:
births - deaths = growth
Explanation:
(births - deaths) + (immigrants - emmigrants) is what you would normally use to calculate the growth of a population, but because they can't move, you can cut out the immigrant and emmigrant part of the equation.

Answer:
The correct answer will be option-A
Explanation:
Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.
The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.
This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.
Meiosis is a kind of cell division. It will lead to 4 daughter cells which each has only half of their chromosomes comparing to the parent. The end product has less chromosomes than the original that's why it's called reduction division.
Meiosis is important because the products are usually seen in gametes, which is sperms and eggs. If they get fertilized, they will form a zygote, and this is reproduction. Meiosis makes sure that the zygote has the right number of chromosomes, like half and half equals the correct amount chromosomes the organism should have. This also leads to diversity which is very important and a must in sexual reproduction.
