Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?(1 point) by observing cellular respiration under bright light conditions

by observing cellular respiration only when photosynthesis occurs

by observing cellular respiration by studying biomagnification

by observing cellular respiration under the absence of light

Just took this - it is: by observing cellular respiration under the absence of light.

Explanation:

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
