Biology

Luba_88 [7]3 years ago

In a one word response,  mitosis.
In an explanation: Before the replication process, an ordinary sex cell contains only has 23 chromosomes. That is half the amount of a normal cell. So when the cells join together they make up the 46 pairs.  Then through replication and division(i.e mitosis), the cells are copied to form in short a tiny human.  You then forever live with the same amount of chromosomes in your normal cells.

How students are disscussing natural selection in bacteria
Elis [28]
Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).
