Answer:
DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.
If these are the choices:
The ability to halt the cell cycle in response to DNA damage.
The ability to halt the cell cycle in response to the chromosomes not properly aligning on the metaphase plate.
The ability to repair DNA damage.
The ability to activate Cdks.
The ability to stimulate cell death processes if the cell is irreparably damaged.

Red blood cells. Red blood cells (also known as erythrocytes) are cells in the blood that carry oxygen to all parts of the body. They are made in the spongy marrow inside the large bones of the body. Bone marrow constantly makes new red blood cells to replace old ones.
. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water, and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells, white blood cells and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.

According to MyPlate, a mini bagel would represent ONE (1) ounce from the grain group.
MyPlate includes dairy products, vegetables, fruits and proteins that is useful for making a healthy diet pattern. It was introduced in 2011, for those who want to lose weight.
The continental places around the Pacific Ocean have lot of volcanic activity.
Explanation:
The Pacific plate is an oceanic plate. It borders several continental plates. On all sides, the Pacific plate is subducting below the other plates. The subduction zones have resulted in intense geological activity along the boundaries, which are right next to the continental edges. Along the sides of the continents that are having a boundary with the Pacific plate there are lot of volcanoes and earthquakes.
- The boundary between the Pacific plate and the other plates around it makes up the Ring of Fire.
- The Ring of Fire stretches mostly on the edges of the continents, surrounding the Pacific Ocean, and it is the place where most of the volcanoes on Earth are located.
- The formation of volcanoes has influenced the topography of the edges of the continents, and all of them are mountainous along the coastlines.
- All of the volcanic activity and the subduction result in cracking of the crust and adjustment of it, resulting in release of lot of energy, or as we know it - earthquakes.
