Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
<h3>WHAT IS MEIOSIS?</h3>
Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.
Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.
Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.
Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

The appearance of a straight and
rigid "pipestem colon" is characteristic of chronic ulcerative
colitis. Ulcerative colitis is an inflammatory bowel disease that causes the inflammation
and ulcers in the colon. The chronic ulcerative colitis is the rare form of
colitis that affects the entire colon and causes severe pain, profuse diarrhea,
bleeding, fever and inability to eat.

Answer: lower reproductive potential
Explanation: Evolutionary psychologists focused on what today is sociobiological approach to sexuality shaping the pattern of human sexuality. This considers that women's parental investment in reproduction is greater than men's, because human sperm is more abundant in quantity than eggs, and the fact that women must carry their young in the womb for several months as well as nurture them for a considerable time after birth. This tends to make women more selective in their choice of mates than men and is seen as a limiting factor in regards to sexuality compared to men.
According to social learning theory however, sexuality is a learned behaviour which arise from studying our environments. The attitudes of parents and grown ups in the society tend to shape our perspectives and expectations which expressing sexuality is a part of.
Ans.
Blubber is a fat-storage organ in mainly water-living mammals. It stores a large amount of brown fat tissue (brown adipose tissue) in young animals as compare to the adults that provides extra thickness to it. The extra amount of brown adipose tissue provides heat that acts as an effecient thermal insulator and helps on thermal regulation.
Thus, the blubber in baby dolphin shows a different composition of fat storage tissues that helps to survive them in cold temperature of ocean in their early stages of development.
