Answer:
the correct answers are C and D: "<em>Both partners are able to grow on substrates on which each would not be able to grow on their own</em>", and "<em>The fungi receive carbohydrates and, in some cases nitrogen, from the algae, while the algae gain a "home" that anchors them on the substrate</em>".
Explanation:
Lichens are the result of a symbiotic association between algae and a fungus. These two organisms must cooperate to survive in places under certain inhospitable conditions, where otherwise, they would not be able to survive by themselves. Algaes are the photosynthetic organisms that provide carbohydrates to fungus. These last ones, get the carbon and energy they need to grow, and in exchange, they protect the algae from dehydration and radiation, and they might also provide minerals for their survival. Algae can also get a way to get attached to the substrate. When instead of regular algae, there is a prokaryotic cyanobacterium, these can also supply with fix nitrogen to fungus, in the form of nitrogenous compounds.
Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
