Mitosis produces an exact copy of the original containing the same 46 chromosomes as the original cell

Meiosis produces 4 individual sex cells ( gametes) with only 23 chromosomes in each. This is so when a sperm cell and and egg cell meet the combine to make 46 total chromosomes with genes from each parent

Answer: The options are not given, here are the options.

A. One species is much better competitor than the other.

B. Periodic disturbances allow for coexistence.

C. Two species tended to use different resources.

D. The two species experienced interference competition and not exploitative competition.

The correct option C.

Two species tended to use different resources.

Explanation:

From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.

Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

Answer:

frontal

Explanation:

  • In a mammalian brain, there are four major lobes that are present and one of them is the frontal lobe.
  • The frontal lobe is mainly rich in dopaminergic neurons and thus, it is mainly concerned with functions such as memory, reward, motivation, planning, attention, etc.
  • The process of break down of tissues and cell death in the tissues is referred to as atrophy and since the frontal lobe is associated with the functions as mentioned above its atrophy would lead to a slow decline in these functions.
  • Since Mr. Klondlike behavior is changing his blunt comments are most likely a result of atrophy of the frontal lobe.

Why dominant traits may not necssairly be more common in a population
nataly862011 [7]
This isn't always the case and there is no reason it should be .Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive. Let's take eye color as an example.
