Answer:
The frequency of bb individuals between successive generations <u>wasn't always the same because of natural selection. The capacity of reproduction decreased by a small portion.</u>
Explanation:
Natural selection is the reason why the reproduction of bb generations wasn't always the same. The randomly selection of mates to reproduce was also variable.
B. Shifting their growing range towards the equator
Oxygen atoms in a water molecule are partially negative, so the sodium ions (Na+) should be drawn to them... vice versa, the Hydrogen in a water molecule is partially positive... which should interact with the negatively charged chlorine (Cl-) ion.
<h2>Capillary Smooth Muscle Contraction</h2>
Explanation:
- Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
- Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
- Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
- All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction
