4. Analyze Explain why the form of
trapecia [35]

Analyze Explain why the form of  reproduction is given below

Explanation:

1.Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce a organism composed of cells with two sets of chromosomes (diploid).

2.Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants.

3.Sexual reproduction does not occur in prokaryotes (organisms without cell nuclei), but they have processes with similar effects such as bacterial conjugation, transformation and transduction, which may have been precursors to sexual reproduction in early eukaryotes.

4.In human reproduction, each cell contains 46 chromosomes in 23 pairs. Meiosis in the parents' gonads produces gametes that each contain only 23 chromosomes that are genetic recombinants of the DNA sequences contained in the parental chromosomes. When the nuclei of the gametes come together to form a fertilized egg or zygote, each cell of the resulting child will have 23 chromosomes from each parent, or 46 in total.

5.In plants only, the diploid phase, known as the sporophyte, produces spores by meiosis that germinate and then divide by mitosis to form a haploid multicellular phase, the gametophyte, that produces gametes directly by mitosis. This type of life cycle, involving alternation between two multicellular phases, the sexual haploid gametophyte and asexual diploid sporophyte, is known as alternation of generations.

6.The evolution of sexual reproduction is considered paradoxical, because asexual reproduction should be able to outperform it as every young organism created can bear its own young. This implies that an asexual population has an intrinsic capacity to grow more rapidly with each generation.This 50% cost is a fitness disadvantage of sexual reproduction. The two-fold cost of sex includes this cost and the fact that any organism can only pass on 50% of its own genes to its offspring. One definite advantage of sexual reproduction is that it impedes the accumulation of genetic mutations.

7.Sexual selection is a mode of natural selection in which some individuals out-reproduce others of a population because they are better at securing mates for sexual reproduction.It has been described as "a powerful evolutionary force that does not exist in asexual populations

Why do we need to study, talk and explore the Male and Female Sexual Anatomy
Serga [27]
We study sexual anatomy to better understand the process of reproduction in humans. It also can help us better understand how a majority of animals reproduce, and how it can influence ecosystems. I hope this helps, and please mark as Brainliest answer!!

This finding indicates the damage of the mid-brain
This is evident due to the Decerebrate posturing, which is characterized by abnormal extension in response to painful stimuli, that indicates damage of the midbrain. On the other hand, damage to the diencephalon or cortex, abnormal flexion, occurs when a painful stimulus is applied. While medulla damage results in flaccidity.
