The correct answer is - a population that feeds on many types of prey.

The predators that are highly versatile in their diet are usually the ones that get over through crises periods, dying out of species, natural disasters... This is due to their ability to adapt to feed on various prey animals, so they are not dependant only on one or two species for their survival. Also this type of predators have developed multiple hunting strategies, unlike the highly specialized predators.

A perfect example for this is the survival of the cougar and the dying out of the smilodon. While the smilodon was a highly specialized predator for only certain type of prey and only one hunting strategy, the cougar was and still is a predator that hunts everything from rodents to birds, and from rabbits to elks. So when a change occurred in the ecosystem, the smilodon died out because its prey died out and it was not able to feed itself, while the versatile cougar managed to survive because it was able to prey upon most of the animals and had perfected multiple hunting strategies.

The survival of a species of predator will depend on its carrying capacity and the growth rate. The carrying capacity is determined by the amount of food resource and the spatial constraints. The predators will grow to the maximum number permitted by their carrying capacity of the inhabited niche. We call this point of max carrying capacity as the stable fixed point. If the carrying capacity remains unchanged in a niche, then a reduced number of predators will recover their numbers quickly to reach the stable fixed point. The maximum sustainable yield is the point on the growth curve of predators. At this point, the population of predators is exactly half the times its carrying capacity. Any disturbance leading to MSY can be considered a non-disturbing change or neutral change, as the population tends to recover past MSY point.

Answer is a population at its maximum sustainable yield.

Why does your arm feel numb if you put too much pressure on it?
serious [3.7K]

Answer:

If your cartilage, muscles, or tendons put too much pressure on a nerve, it might not be able to work right. This can cause numbness. An injury or overuse can cause a pinched nerve. Sometimes it's due to health problems like arthritis, a narrowing of the spaces between the bones in your spine, or a tumor on the spine.

What causes the protein digestion there?
DanielleElmas [232]
The reason of the protein digestion process is that the dietary protein is reduced into a group of amino acids in the gastrointestinal tract. Proteins are globular molecules that are comprised of smaller molecules called amino acids.

A man with cystic fibrosis of the pancreas wishes to marry a young woman whose family has never had an individual born with the
mixas84 [53]

Cystic fibrosis is a recessive condition; meaning if a dominant condition takes over it will not be seen in the offspring. The man genotype with cystic fibrosis can only be this: cc (when c is equal to the cystic fibrosis and C is equal to not having one). The woman with no history of cystic fibrosis can possibly have either of these two genotypes: Cc or CC.

To see their offspring’s possible genotype, we’ll use a punnett square let’s start with Cc:

                C             c

c              Cc           cc

c              Cc           cc            There is a 50 % chance of the child having cystic fibrosis.

To see their offsprings possible genotype with CC:

                C             C

c              Cc           Cc

c              Cc           Cc           There is no chance that the child will have cystic fibrosis.
