Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance

Ok here we go:

Science starts with observing which leads to hypothesis, which is tested by experiments.

A book that is 2 Newton (N) on earth would be 7N on the moon. True or False? Why?

Gnom [1K]

False

The gravitation on earth is 6times than that of moon

$\\ \sf\longmapsto Force\propto Acceleration$

Hence the object which weighs 2N on earth will weigh 2/6=0.33N on moon

"Consider the reproductive isolating mechanisms described above. Do any of these apply to human beings? Write a few paragraphs i

8090 [49]

Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.

Alcoholism results in the inability of liver cells to properly digest proteins. Which of the following organelles is most likely

dangina [55]

Cells are made up smaller units called organelles that undertake various critical roles in the activities of the cell. Some of these organelles include, mitochondria whose major function is formation and production of energy in the form of ATP, Ribosome is an organelle involved in the protein synthesis, lysosome is involved in the destruction of old and worn out tissues and organelles, Golgi apparatus or complex helps in transportation, modification and packaging of secretions such as proteins and lipids. Therefore, alcoholism affects the activity of lysosomes in the liver since they are tasked in the digestion of proteins using hydrolytic enzymes.
