Answer:
Passive transport is the movement of particulars across the membrane from area of <u>high</u> to an area of <u>low</u> concentration.
Explanation:
Passive transport is a transmembrane cellular transport mechanism characterized by the fact that it does not require energy.
What enables passive transport is the concentration gradient of a particle, which moves across the membrane from a site of high concentration to a site of low concentration.
Two known forms of passive transport are <u>simple diffusion</u> and <u>facilitated diffusion</u>.

A. Plant cells have cell walls and chloroplasts, Animal cells do not.
Explanation:
The correct answer is - B) ATP and NADPH.
The products of the light reactions of the process of photosynthesis are the ATP and NADPH. The small amount of ATP produced in this process and the energy carrier NADHP are crucial for the functioning of the organisms that use the process of photosynthesis, and the reason for that is that these two are used by the organisms to create glucose, or rather sugars, in the process called the Calvin Cycle. The glucose is what these organisms use as their food, a food they they manage to make themselves, thus making them producers. If the light is missing, then the process of photosynthesis can not be performed because the formation of ATP's will be stopped, as well as the formation of NADHP, so the organisms will not be able to produce their own food.
Answer:
The history of the human evolution can be studied by the fossil and DNA evidence. The similarities and advancement in certain characters has revealed the human evolution.
Different evidences like change in the diet, locomotion, brain size, walking ability as compared with the present species and species appeared 6 million years ago. The human genetics evidence and different paintings explain the culture of earlier homo species.The H. sapiens species has highly advance character that help them to survive than any other hominid species. The neanderthals extinction might occur due to their aggressive behavior, low social ability and their large cranial size.
