The answer to number 14 is earth worms
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.
Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.
Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.
Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.
Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.
