A) Law of Dominance explains why there is a 75% chance
Q. RNA is not a component of the cell membrane
As the exercise progresses, muscular activity increases venous return. This increases the pre-load on the right ventricle. During venous exercise, the rhythmic pump of the muscles facilitates venous return by forcing the blood through one way valves that lead to the heart. Additionally, increased lung activity which creates a change in thoracic pressure that draws blood towards the heart. Regular exercises improves the venous return by increasing total blood volume, increasing end diastolic volume and increasing the size and contractile strength of the heart muscle.
Answer:
B. an electron and a proton
Explanation:
An element is a pure substance that cannot be broken down into any other substances because it consists of only one type of atom. Each element consist of three types of sub-atomic particles known as protons, neutrons, and electrons. Protons having a positive charge, neutrons a neutral charge, and electrons a negative charge. Both protons and neutrons are both the same size, but have opposite charges. Protons and electrons attract each other because opposite charges have a attraction to each other.
Therefore, Option 2: An electron and a proton, is correct.
