Explanation:
Yo Is it giving birth I think it should be
Answer:
It is difficult to obtain a final conclusion with this information, but it is possible that the sample doesn't contain living organisms whose genetic material is composed of DNA. Another possible reason for this result is that the DNA extraction protocol used in the experiment is not suitable for this sample.
Answer:
D) Passing of electrons from Photosystem I to electron transport chain.
Explanation:
The NADPH is generated in the thylakoid membrane first in order to energize the second stage of photosynthesis (Calvin Cycle). Calvin Cycle takes place in the stroma, so that choice is out. Choices A, B, and C are in cellular respiration, and NADPH is not made in that process, so that leaves choice D.
Answer:
heterotrophs survive through respiration, using oxygen and an energy source (carbohydrates, fats or protein) to produce ATP, which powers cells. They depend on other organisms for food and oxygen. Photosynthesis benefits heterotrophs in several different ways. First, "photosynthesis consumes carbon dioxide (a waste product of respiration) and produces oxygen (necessary for respiration)." Heterotrophs therefore depend on photosynthesis as a source of oxygen. In addition, "photosynthesis sustains the organisms that heterotrophs consume in order to stay alive. Even if a heterotroph is strictly carnivorous and does not eat plants, it must eat animals that eat plants to survive."
Climate change is already beginning to transform life on Earth. Without action, the impacts of climate change threaten to catastrophically damage our world. But by rallying people around the world to be a part of the solution, together we have the power to limit the effects of climate change.
i hope this helps!!
