Answer:

Most scientists would agree unequivocally that humans have greatly affected the process of evolution, from the rise of antibiotic and pesticide resistance to the largely human-caused increase in the extinction rate. Our effect on the process of evolution even extends to our own species' evolution.

In the peppered moth scenarios what is the variation? And the selection?
Morgarella [4.7K]

Variation is number of alleles for the wing color of the peppered moths. The wing color ranges from pure white to pure back.

Selection pressure is predation by birds.

Explanation:

In the wake of the industrial revolution, white-winged peppered moths had a large allelic frequency in the population compared to black-winged peppered moths. However, when the environment changed due to soot produced by industries (making the environment darker) white-winged peppered moths reduced while that of black moths increased.

This is because black moths were able to blend in and camouflage in the dark environment than white-winged peppered moths that stood out to their predators. Black moths, therefore, had an increased chance of reaching adulthood and passing their genes to the next generation. This increased the allelic frequency of black-winged peppered while that of white-winged moths reduced in the population.

Which relationship is being shown in the graph
goblinko [34]

The correct answer is prey predator relationship.

The given graph possibly shows the prey predator relationship, in which the prey is shown in red and the predator is shown in blue. It is observed that the predator population generally remain less than the prey, in order to get food easily.

The prey predator relationship shows that if the population of the prey start increasing, then the population of the predator would also increase, as the predators have abundant of food. But when the population of the prey start decreasing, the predators start to decline due to the starvation.

Describe each step of endocytosis
s2008m [1.1K]

Explanation:

The Basic Steps of Endocytosis

The plasma membrane folds inward (invaginates) forming a cavity that fills with extracellular fluid, dissolved molecules, food particles, foreign matter, pathogens, or other substances.

The plasma membrane folds back on itself until the ends of the in-folded membrane meet. This traps the fluid inside the vesicle. In some cells, long channels also form extending from the membrane deep into the cytoplasm.

The vesicle is pinched off from the membrane as the ends of the in-folded membrane fuse together. The internalized vesicle is then processed by the cell.
