Answer:
carbon dioxide at normal atmospheric concentrations is limiting for the metabo- lism and growth of most land plants of the world. These plants share a comparable photosynthetic metabolic pathway, termed C3 photosynthesis. With an increase in CO2 there is an increase in photosynthesis and growth.
Explanation:
The cytokine describes the group of proteins such as interferons and interleukins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.
<h3>What is a cytokine?</h3>
They are messenger molecules with a glycoprotein structure, whose lifetime is short and generally secreted in cascades.
They are produced by different activated cells, responsible for innate and/or acquired immunity, and regulate the immune and inflammatory response.
Therefore, we can conclude that the cytokine describes the group of proteins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.

Answer:
Although the graph was missing, I managed to find it on another source. According to the given conditions, correct answer is <u><em>option C</em></u><u>. A dog stop at his home for 5 seconds</u>.
Reason:
In the graph, The dog was west of his home then he came back, he stopped at his home then runs to other direction (East).
When the dog was running from west to home, his running speed or velocity was 1 m/s which was then decreased to 0 m/s after reaching home. Here (at home) the dog stopped for a while (5 seconds according to the graph), and his velocity was 0 m/s. Then, he started running again to other East direction with velocity -2 m/s (opposite direction).
