If a cell with 12 chromosomes undergoes mitosis, how many daughter cells result and what is the chromosome number in each daught
VMariaS [17]
Mitosis is a kind of cell division that produces 2 daughter cells that is genetically identical to both the other daughter and the parent cell.

By the word genetically identical, it means that they have the same number of chromosomes.

This process starts by a parent cell doubling their chromosomes, then, it divides, and therefore each daughter cells receive the original number of chromosomes.

Therefore, the answer to this question is 2 cells, 12 chromosomes each.

Why are gymnosperms no longer restricted to moist environments, as are ferns and mosses?
erastovalidia [21]

Gymnosperms are no longer restricted to moist environments, as are ferns and mosses because they have evolved to produce non-flagellated pollens that do not require water or moisture to reach the egg whereas ferns and mosses have flagellated sperm that needs moisture to swim towards the egg.

Another major evolutionary adaption in gymnosperms is the production of seeds instead of spores since seeds contain their own nutrition in the form of endosperm, seeds can travel large distances through wind or animals and can germinate when they find suitable conditions. Seeds can remain dormant for several years whereas spores have a shorter lifespan.
