Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken.
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Answer:
68 1/2 foot length
Or 22 5/6 yards.
Explanation:
The yard length of the part of the goal post
The base (10 foot)
The crossbar (18 1/2 )
And two arms (20 foot each)
Let's sum up the total yards
=(10 + 18 1/2 + 20 +20) foot
= 68 1/2 foot length
Or 22 5/6 yards.
Answer: transporting substances in a cell
Why: In eukaryotic cells, endomembrane system refers to the set of membranes present inside the cytoplasm which form single functional and developmental unit. The membranes are either connected directly or indirectly and exchange material with the help of vesicle transport. The main function of this system is to modify, pack and transport the proteins and lipids in and out of the cell. The main organelles which form the endomembrane system are- nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles.
Small intestine is modified due to the presence of micro villi which has ability to increase it's size
