Why does water move through a membrane?

Biology
1 answer:
AnnZ [28]3 years ago
7 0

Answer:

The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.

Explanation:

The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water.  In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.

solong [7]

Answer:

Multicellular

Eukaryotic

Heterotrophs

Explanation:

Both cells of fungi and animals are eukaryotic meaning they have  nucleus and organelles. They are multicellular organisms (meaning they are composed of many cells). Their cells are also heterotrophic meaning they depend on organic molecules for energy as opposed to plants that can make their food from abiotic factors. Fungi, however, digest their molecules extracellularly while animals do it intracellularly.

icang [17]

Answer:

80 dB

Explanation:

Sound intensity is inversely proportional to the square of the distance traveled by the sound.

Thus;

r1^2 divide by r2^2 = L2divideL1

where r= distance (m)

L= sound intensity (decibal dB)

8squared divide by 4 squared = L2 divide 20 dB

L2 = 4 × 20

L2= 80 dB

This means that the sound is increased from 20 dB to 80 dB.

What specific key factor starts the breathing process in a newborn infant?
kvv77 [185]
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.

Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.
