Answer:

1.Energy unidirectionally flows through an ecosystem, whereas matter generally cycles within an ecosystem.

Explanation:

In an ecosystem, energy from the organisms of one trophic level to that of next occurs by the process of feeding. The flow of energy follows a unidirectional path which means that energy from producers is carried to the primary consumers, secondary consumers and so on. It does not flow in reverse direction (from consumers to producers).

On the other hand, matter such as carbon, nitrogen, phosphorus, etc. are cycled via various biogeochemical cycles. For instance, plants intake carbon from the air in the form of CO2 and form organic nutrients. These organic nutrients carry the carbon from plants to herbivores and then to the consumers of higher trophic levels. However, when plants and consumers die, the carbon present in their tissues is decomposed and is released back to the surroundings. In this way, the carbon cycle cycles carbon in an ecosystem.

Answer:

Phosphorylation within the nuclear export signal interferes with the function of the signal.

Explanation:

In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.

However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
