Describe how the process of photosynthesis led to an increase in cellular respiration and more complex cells
koban [17]

Answer:

<u><em>BRIEF EXPLANATION</em></u>

Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.

Explanation:

<em><u>MAIN ANSWER TO THE QUESTION.</u></em>

Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.

Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.

All compounds are negatively charged, true or false?
Alenkinab [10]

Answer:

false

Explanation:

"Electrons are the "material" of the charge that is flowing. Therefore, current can never cause a metal object to become positively or negatively charged, because the net number of electrons in the metal object will never change due to current flow."

zhuklara [117]

Answer:

The population has evolved because there was a change in allele frequencies.

Explanation:

The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.

The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.

Thus, the correct answer is option (D).
