When you exercise and your
body temperature rises, how
does your body maintain
homeostasis? What are some
things that happen? How do you
cool off? What happens to your
breathing? Blood flow?
Answer:
During exercising, your body's temperature levels up and one of the body's mechanisms of homeostasis is perspiration, which is sweating. Sweat helps cool off the body by excreting the heat to the exterior surface f the body and it gets rid of excess fluids and salts. The breathing rate also gets higher due to the physical activity. Blood flow will increase as well, as the blood vessels dilate and get wider allowing more blood to pass through.

Enzymes are composed of what organic molecule? A. Sugars B. DNA C. Fatty acids D. Proteins
Answer: D. Because enzymes are protiens but they are produced of amino acids
Explanation:
Enzymes are composed of proteins, that assist our bodies' chemical reactions to move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
What is the function of enzymes?
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Among countless other functions, they are crucial for breathing, food digestion, and the health of the muscles and nerves. Numerous enzymes can be found inside each cell of the human body. Each cell's internal chemical operations can be aided by enzymes.
Digestion enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most significant digestive enzymes are produced by it.
Therefore, in the human body, enzymes aid in accelerating chemical reactions, hence option D is correct.

Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of carbon dioxide by breathing it out and pick up oxygen deliver the oxygen to all the cells in the body(to participate in cellular respiration and generate energy.
Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.
