Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

Answer:
peripheral circulation is decreased
Explanation:
Systemic circulation, also called large circulation, transports blood to all tissues of the body. In addition, it also ensures the nutrition of the vessels that constitute the small circulation, or pulmonary circulation. It is called large circulation or peripheral circulation. When this circulation is slowed there is a delay in the time to recharge hair, which must occur simultaneously.
The infant in question is experiencing a delay in capillary recharge time, so we can conclude that the baby's peripheral circulation is decreased
Answer: Mechanoreceptors
Explanation: These receptors perceive sensations such as pressure, vibrations, and texture.
Answer:
In the given case, it can be concluded that very less amount of telomerase is being produced.
Explanation:
Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.
Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.
