Answer:
option D: GABA ( gamma-aminobutyric acid )
Explanation:
The amount of neurotransmitters released during depression can not be properly measured. The neurotransmitters released due to anxiety are GABA, serotonin, Cck, and glutamate.
The rise in level of neurotransmitter, GABA in depression causes anxiety. Thus, option D is correct.
Answer:
Yes, I agree with the given statement.
Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
Answer: I'd say C
Explanation: Small plants are at the bottom of the ecosystem, which means they have to start it out. I'm not sure tho.
Answer;
Chlorophyll
Chlorophyll is the green pigment found in plants traps energy from the sun for photosynthesis.
Explanation;
-Green plants requires food for their day to day activities, thus they use the process of photosynthesis to make their own food, which they use to generate energy or store for the future use in form of starch.
-Chlorophyll a pigment that gives plants their green color is vital during the process of photosynthesis. During the first phase of photosynthesis light dependent stage), chlorophyll traps sunlight which is used to split up water molecules to oxygen atoms and hydrogen ions, a process called photolysis.
The answer is D, algae.
—Evidence—
•] Protozoan definition: a single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an amoeba, flagellate, ciliate, or sporozoan.
•] it does not feature algae, therefore it’s D.
