The answer to this question would be simple squamous epithelium.
When you need to supply oxygen or nutrient, the thinner cell layer the faster it can move. In this case, simple squamous epithelium is better since it provides protection but can let the nutrient transported quickly.
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
Explanation:
The outermost electrons of the element vanadium (A.N.=23) will be in forth energy level (n=4) of the atom.
We know, the capacities of orbital as K,L,M,N = 2,8,8,18 respectively, as 23 is larger than the sum of 2,8,8 it will be in next higher orbital which is forth.
Again, In short, Your Answer would be Forth Energy level
Hope this helps!
Answer:
Plant cell has larger vacuoles.
Explanation:
Vacuole is a fluid filled structure found in cells of the plants, certain animals, protists, fungi, bacteria etc. Vacuoles found in plant cells are larger than that in animal, protist, fungal, and bacterial cells. The vacuole inside a plant cell stores water. It also helps to maintain the turgor pressure of the cell. The functions of the vacuole include isolating materials that might be harmful to the cell
, maintaining an acidic internal pH
, supporting the plant structures such as leaves and flowers.
