How would a small, uncharged lipid move across the cell membrane?

Biology
1 answer:
ElenaW [278]3 years ago
5 0

Answer:

Through simple diffusion, down the concentration gradient.

Explanation:

The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

Darya [45]

Whales use their lower jawbone to the middle ear. whereby they can ear clearly while they are in the water. Human ears and dolphins ears they work the same . They receive sound directly from the air.

In similar way dolphins and human ears are placed in basic anatomical location which is same as on the head. Without a medium hearing is not possible.

The medium sound for human is air. Sound travels 343 meters per second in air and 147 meters per second in water. The most effective way of transmitting sound waves is through water.

We can say that the sound will be fast to travel in medium if the molecules are closer.

Because Darwin did not know about the work of Gregor Mendel, he could not explain how organisms pass heritable traits to their o
anastassius [24]

Explanation:

Both Darwin and Mendel proposed their theory at the same time but they never communicated with each other. They both explained the population and studied the variation between them and in them.

The variation within a population could be of two types: the discontinuous traits and the quantitative trait.

A discrete trait refers to a trait that is usually controlled by only one gene that is only two alleles or two variants are observed in the population whereas the quantitative trait is a trait that can be determined by more than one gene like the variation in height.
