Answer: A the chromosomes from another parent cell were introduced
Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.
DEPRESSION. Eating disorder and depression goes hand in hand which also gives almost the same symptoms such as sadness, agitated, sleep problems, loss of interest. Treatment for this condition must be tailored specifically to the person and must be evaluated properly.
Answer:
Mitosis is a neccessary process that helps the creation of life. The purpose of it is to make cells to regrow and replace old, dead, and/or wornout cells. What happens during mitosis is that a single cell will duplicate each and every one of its contents. This includes chromosones and more. It will then split into two identical daughter cells. This is how it makes it's newer cells.
Population decrease and extinction
Answer:
The question lacks options, the options are:
A) All cells contain a nucleus.
B) All cells come from other living cells
C) All living organisms are made of one or more cells.
D) Cells are the basic unit of structure and function of all living things.
The answer is A
Explanation:
In 1830's, three scientists named; Mattias Schleiden, Theodor Schwann and Rudolph Virchow contributed to describing the basic properties of the cell, which they proposed in their so named CELL THEORY. This widely accepted cell theory has three components:
All living organisms are made up of one or more cells.
Cells are the basic and fundamental unit of life
All existing cells come from cells that have previously existed.
It was not proposed that all cells have a nucleus
