Question

1. pompeii worms, alvinella pompejana, live in tubes along hydrothermal vents on the sea floor. the worms are covered by a layer of bacteria. scientists have discovered that the bacteria insulate the worms from the extreme heat of the vents, and the worms secrete mucus from glands on their backs to feed the bacteria. which of the following terms best applies to the relationship between the pompeii worms and the bacteria? a. competition b. mutualism c. parasitism d. predation 7. when locust populations grow too large for an area, the individual locusts are crowded and food becomes scarce. in response to these conditions, some of the locusts leave the area and find a new habitat. which of the following terms best applies to the response of the locusts that leave for the new habitat? a. commensalism b. emigration c. hibernation d. mutualism

Explanation:

For question 6, mutualism is a symbiotic relationship where both organisms benefit. The bacteria insulate the worms from heat and the worms secrete mucus to feed the bacteria, so it's mutualism. For question 7, emigration is the movement of individuals out of a population to a new habitat due to factors like over - crowding and food scarcity which is what the locusts are doing.

Answer:

1. b. Mutualism
2. b. emigration
