Why might larger jaws and teeth become more common in jaguar species over time? In your response use the 4 principles of natural selection to support your answer. (Genetic variation, overpopulation, competition, and adaption) Please help it's due today

Answers

Answer:

Larger jaws and teeth may become more common in jaguar species over a period of time for a few reasons. To start off with, the genetic pool needs to prompt the species to have multiple offspring of different genealogy lines (non-inbred). Those offspring with the new attributes would have to adapt and survive. They wouldn't necessarily need to do better than the normal variation of jaguar, they just need to do well enough to mate. In terms of mating, the offspring with the mutation would have to mate with each other since the mutation would most likely be recessive. Over time, with more offspring that contain the mutation and keep breeding together, the recessive gene would become dominant (I think that's how that works) within the population. Once the population is high enough, there would be a competition between the normal variation and new variation of jaguars.  Assuming the new variation out-competes the normal variation, natural selection had occurred and you have a result.  I hope this helps!

the change in electrical potential that occurs when an impulse passes through a nerve cell

Answers

Answer:

The answer to this definition is: ACTION POTENTIAL

Explanation:

Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.

Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.

Once a fossil has been formed, it still might not become part of the fossil record. Describe two natural processes that might destroy the fossil.​

Weathering by wind, water, and sun can destroy a fossil by wearing it away.

the first one is by melting because of the extreme pressure and heat and the other way is being washed away or something
