Answer: A. Extirpation
Explanation:
The term extirpation is also known as local extinction. It is situation whereby a particular species ceased to exist in an environment where it was once found, though it's existence is still observed elsewhere.
Extirpation maybe as a result of unfavorable environmental and human factors such as hunting, food scarcity and climate variation.
<span>Pancreas
The pancreas is responsible for producing mixes of enzymes that are called pancreatic juice. This juice neutralizes acidic chyme that enters the small intestines. The pancreatic juice is responsible for helping the digestive system to digest proteins, fats, and carbohydrates. </span>
Answer:
Letter C would be the best possible answer choice.
Without food, the deer will starve and die, unable to reproduce new deer. The wolves will eat the dead dear but run out of deer since there are none to reproduce more.

Answer:
Hyperpolarization means that the membrane potential becomes more negative than the resting potential.
Explanation:
The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.
When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.

Answer:
speciation is when one species splits off into multiple species.
In-depth answer:
Speciation can happen in 4 different ways, the first being Allopatric Speciation, where 2 groups of the same species are physically separated for extended periods of time, and when they're re-introduced, they don't breed.
Sympatric Speciation is when 2 groups of the same species aren't seperated, but form different behaviors that isolate them reproductively (the groups wont inter-breed)
Parapatric Speciation is when 2 groups of the same species are suddenly placed into a new environmental niche, and adapt in different ways to fill that niche.
Quantum Speciation is much less recognized, but it's when a new species rapidly evolves and 'buds off' from the original group
