Explanation:
Genetic drift is a phenomenon which changes the allele frequency of a population due to a natural catastrophic which is random. The phenomenon occurs in the small population and chances of change in the allele frequency are very less in the large-sized population.
The size of the population is affected by the mating also and the monogamous species have more genetic diversity compared to the polygamous species but the polygamous mate to maximize the chances of breeding. These lead to the change in the genetic drift and both the polygamous and monogamous species will be affected by the drift process.
Answer:
it controls the heartbeat
it controls the movement
Parent cell give rise to daughter cell being genetically identical because of it replicates the DNA, so after mitosis, both daughter cell is genetically identical to the parent cell.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the amount of chromosomes as the parent cell. Because DNA replicates to complementary to other DNA strands.
The mature cell that is undergoing cell division is known as the parent cell or the mother cell, and the new cells that emerge at the conclusion of the cell division are known as daughter cells.
Therefore due to DNA replication daughter cell is genetically identical to the parent cell after mitosis.

Answer:
after mitosis there are two daughter cells, which are genetically identical to the parent cells.
Explanation:
The daughter cells are identical to the parent cells because the cell copies/ replicates its chromosomes. Then it splits the chromosomes equally so that each daughter cell has a complete set of chromosomes.
b)Their vision is better than their hearing.
c)Their hearing and vision are about the same.
d)Their hearing is better than their vision.
It is TRUE about most newborns’ hearing and vision that Their hearing is better than their vision. Correct Option is 4.
Most newborns have better hearing than vision. Newborn infants typically have a well-developed auditory system, allowing them to respond to sounds soon after birth. They can perceive a wide range of auditory stimuli and are sensitive to different frequencies and intensities of sound.
On the other hand, their visual system is not fully matured at birth, and newborns have limited visual acuity and color vision. Their ability to focus on objects and perceive details improves gradually over time as their visual system develops. Therefore, during the early stages, newborns generally have better hearing capabilities compared to their vision.

Answer:B
Explanation: At birth, a newborn's eyesight is between 20/200 and 20/400. Their eyes are sensitive to bright light, so they're more likely to open their eyes in low light.
B. Combinations of the 20 amino acids combine to make proteins
C. Proteins are synthesized via transcription and translation at the ribosome
D. The four nitrogen bases of DNA combine is threes to produce only 20 amino acids
Answer:
Option A, B and D apply except C
Explanation:
All DNA contains the same four nitrogenous bases, A, T, C, G and these bases combine in threes to produce 20 amino acids which make proteins.
On the other hand, DNA is transcribed in the nucleus to mRNA transcript and then sent to the cytoplasm for translation. mRNA is then translated to proteins with the aid of the ribosomes. Thus making option C wrong.
While mapping the motor cortex, researchers Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space
The majority of the afferent fibres that enter each region of the cerebral cortex come from a single thalamic projection nucleus. This thalamocortical projection is topographically organised so that discrete thalamic volumes project to discrete fields in the cortex, while continuous thalamic volumes project to a continuous region in the cortex. A point-to-point projection could be thought of in this respect, however this oversimplification ignores the mutual overlap of thalamic fibres inside their "modular" cortical arborization zones . Because the cerebral cortex is a two-dimensional surface and the thalamus is a three-dimensional body, the topographical depiction of the thalamic projection nuclei over the cerebral cortex is a topological problem.
Hence, Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space.
