Answer:
The fewer fish the less that can reproduce.
Explanation:
marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.
More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.
What is reproductive rate?
The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).
What is extinction?Extinction is a situation in which something no longer exists.
When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

Answer:
I breathed heavily and hugged Dad one last time. I was going to miss him. Dad was serving in the Union, and he was leaving us behind. Mom was crying and hugging him all she could. We eventually let him go, and he went off to war.
My brother yelled in anger at me. "NO!" He said. I wanted to cry as much as I did when Dad left. "The Confederacy is better than the Union!" He yelled. He was 22, so he could serve in the army. And sadly, he did.

Explain the main differences and similarities between somatoform and conversion disorders.
The main difference between somatoform and conversion disorders is that somatoform is conveyed by physical symptoms while conversion disorder is expressed by mental condition.
What do you mean by Conversion disorder?Conversion disorder may be defined as a condition of mental illness where an individual is affected by blindness, paralysis, or other nervous system symptoms that cannot be explained by medical evaluation.
Somatoform affected the psychology of the affected individuals causing physical symptoms. It is also associated with mental illness. It is the similarity between both disorders.
Therefore, the main difference between somatoform and conversion disorders is that somatoform is conveyed by physical symptoms while conversion disorder is expressed by mental condition.

Homologous chromosomes may exchange segments; this is called crossing over. crossing over increases genetic variability. when does crossing over occur?
A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
What are homologous chromosome?Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.
Thus it s well expalined.

7. Discuss the practical and theoretical differences between an interval training program used to improve the ATP-PC system and a program designed to improve the ATP production via glycolysis.
The ATP-phosphocreatine (PC) system is more suitable in conditions of high energy expenditure, whereas glycolysis is a step during cellular respiration.
What is cellular respiration?Cellular respiration is a chemical process by which aerobic cells generate energy in the form of ATP by using foods as a source of energy in presence of oxygen.
During cellular respiration, glycolysis (glycolytic pathway) is the first step for ATP production.
The ATP-PC system is anaerobic, works in hypoxia conditions (oxygen absence), and is faster to provide energy than cellular respiration.
However, the ATP-PC system is energetically less efficient than cellular respiration in terms of the number of ATP molecules produced per unit of glucose.
