Answer: The right answer is -
A) Gene flow
Explanation:
Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.
As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.
Thus, option A) is the right answer.
Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed

<h3>What about cardiovascular system?</h3>
- Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
- Blood vessels also transport waste such as carbon dioxide to be disposed.
- Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
- It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
- The heart, blood arteries, and blood make up the cardiovascular system.
- Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.
- The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
- Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.
