Answer is A all living things need to go through the photosynthesis cycle and need oxygen to sustain life
Answer:
The correct answer will be option-A
Explanation:
The ecological population is the group of the organism belonging to the same species which live or is found in the particular area and can interbreed.
Since in the given question, the redwood trees live in the same geographical area (forest) which can interbreed shows the population. The other examples represent the community which consists of more than one species.
Thus, option-A is the correct answer.
Answer:
D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
Explanation:
Active transport refers to the movement of molecules across biological membranes against a concentration gradient. Active transport can be divided into 1-primary active transport, which requires energy from the hydrolysis of adenosine triphosphate (ATP); and 2-secondary active transport, which requires an electrochemical gradient generated by pumping ions in/out of the cell. The case above described represent a type of secondary transport active because the movement of sodium (Na) ions is used as energy source to move glucose molecules against their concentration gradient.
