Mitosis is a type of cell division that takes place in the somatic cells where two daughter cells are formed with the same number of chromosomes as the parent (diploid 2n). Meiosis is a type of cell division that takes place in the sex cells where four daughter cells are formed with half the number of chromosomes as the parent (haploid, n). In this case, if the gametes were formed by mitosis then it means they would have a diploid (2n) number of chromosomes.

Anettt [7]

Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.

<h3>What do you mean by Natural selection?</h3>

Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.

Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.

Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

A person will most likely develop aphasia as a result of damage to which parts of the brain?
Anna11 [10]

Answer:

The correct answer is Broca's area or Wernicke's area.

Explanation:

Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.

The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.
