<span>Villi are hair-like structures covered with epithelial cells measuring 1.5 mm that line the mucous inner membrane of the small intestine. The epithelial cells of the villi contain microvilli and are responsible for the absorption of nutrients. Being so small and numerous, they effectively increase the absorptive surface area of the small intestine. When the surface area increases, this is the time they absorb the nutrients.
As for plants' root hair cells, they receive nutrients through osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water and minerals are transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.
As we can see, both of them utilize increasing their surface area.</span>
Answer: this is because bacteria that encounter such an environment UNDERGO DEATH AS A RESULT OF WATER LOSS FROM THE CELL.
Option C.
Explanation: Water is a great medium of growth for bacteria. Several experiments have been carried out to support this statement. Also, it is a means by which the bacterium is transmitted from "a site" to another.
The correct answer is option C
The original source of energy is the sun while most of the energy in the organisms is used in the form of energy. The energy from the sun is used by the green plants to make food by the process of photosynthesis and this food is used by the human beings and animals. The energy in animals and human is in the form of ATP.
Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.
Hope this helps, have a lovely day :)
I am assuming you would recommend a specialist.
