Hydrolysis, the diffusion of water across the cell membrane.
Emperor penguins need lungs to breathe. In penguin lungs, air never stops. ... Once the air goes farther into the trachea it splits into two different directions into both lungs. To get the oxygen into the blood cells, it must come "within small distance of the penguin blood cells".
When toucans are removed from an ecosystem it leads to loss of hardwood trees, deforestation, and global warming.
Explanation:
Toucans are very attractive brightly colored large birds which are fruigivore (fruit-eaters). They are specially adapted with a large, sharp but lightweight bill which helps the toucans to reach to branches to pick fruits, berries, seeds mostly which are larger and difficult for the smaller birds to eat.
Their main habitat for the toucan is the rainforests. They are woodland birds and stay mostly on hardwood trees.
Toucans help the rainforest ecosystem to grow by dispersing the seeds of the fruits they eat all around the forest as they keep flying. This makes the species of trees from which toucans pick their fruits to increase and makes the rainforest healthy.
When toucans are removed, then dispersal of seeds becomes less and spreading of hardwood trees will be reduced slowly leading to deforestation and drying up of forest lands.
Bigger hardwood trees play a major role in reducing carbon footprint compared to the softwood smaller trees and this increase in carbon will lead to global warming.
The answer is B). Because Centrioles play role in Mitosis. Prokaryotes don't divide by Mitosis. They divide by binary fission.
Answer:
Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis
Explanation:
Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.
Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
