Answer:
Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>
Explanation:
Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP. The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.

Answer:
d)A...B...C
Explanation:
Hormones are chemical proteinous substances secreted in one location and transported to another location, in order to bring about a physiological effect. Hormones are secreted by endocrine glands which collectively makes up the endocrine system. Endocrine glands include testes, ovary, pancreas, thyroid, adrenal gland etc. A hormone is usually secreted when a change needs to be effected in a target cell.
What happens is that, when a particular physiological effect is needed by a target cell e.g growth, development, homeostasis, repair etc., it sends a negative feedback to the gland that is responsible for the secretion of the specific hormone. The particular endocrine gland, then, secretes the hormone into the bloodstream (ductless), which carries it for absorption by the target cell where it is needed.
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
