Answer:
The hydrophobic tails of the phospholipids
Explanation:
Because the phospholipid bilayer is made up of a hydrophillic head and a hydrophobic tail, the phospholipids spontaneously form a bilayer in water. This is because the hydrophobic tails are repelled by the water, meaning they retreat into one another, whereas the phosphilipid heads are attracted to water. This means the heads form the outside of the layer, and the tails form the inside of the layer.
1. DNA replication produces two identical DNA molecules, called sister chromatids, which separate during mitosis.
2. After chromosomes condense, the centromeres is the region where the identical DNA molecules are most tightly attached to each other.
3. During mitosis, microtubules attach to chromosomes at the Kinetochores.
4. In dividing cells, most of the cell's growth occurs during Interphase
5. The mitotic spindle is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called ,chromatin.
7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides.
8. The centrosomes are the organizing centers for microtubules involved in separating chromosomes during mitosis.
Answer:
increase
Explanation:
As water and ions are lost through exercise, overall blood volume can decrease. To maintain adequate blood volume and blood pressure, renin is secreted to help in the conversion of angiotensin I to angiotensin II. This will cause vessels to constrict and sodium and water to be retained by the kidneys.
Answer:
A) They contain many carbon atoms.
Explanation:
Proteins are considered organic molecules because they are made up of carbon atoms. Proteins give your body energy and allows your body to run the way it does. Proteins also aren't considered organic molecules because they are small, because they are not used by living things, or because they contain nitrogen.

D. meiosis
Because the dna is replicated only one time, then are divided into 4 seperate cells
