Proteins involved in facilitated diffusion are

Biology
1 answer:
Svet_ta [14]3 years ago
6 0

The best answer is C Carrier and channel proteins are involved in facilitated diffusion.

A carrier protein is a transport protein that is specific to a particular type of ion, molecule or substance.

It is a special protein that binds to a  molecule and carries the bound molecule across the cell membrane. The protein changes its shape so that it can fit into the channels that run through the membrane and then goes through the channel with its cargo. 

A channel protein is a transport  protein on the cell membrane and acts like a pore, allowing ions and small molecules to pass through more efficiently.

Difference between palisade cell and fungal cell
satela [25.4K]

Answer:

Explanation:

Plantae and Fungi are two of the three main kingdoms in the domain Eukaryote (the third group is Animalia, which includes you and me).

Many fungi grow in a way that’s similar to plants. They inhabit similar ecosystems and may even form symbiotic relationships together. Mycorrhizae are fungi that grow on the roots of plants, helping the plants take up nutrients in the soil while the plant provides the fungus with sugar. Of course, most fungi don’t look much like plants.

But the differences between fungi and plants are more than just skin (or bark) deep. While mushrooms often inhabit similar ecosystems to plants, molds and yeasts are even more different from plants!

Looking at a plant cell and a fungi cell under a microscope will reveal some interesting similarities and differences.

HELP ME OUT PLEASE
Andrej [43]

Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population

2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die

3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

A cold front moves from the ocean to warmer land. What weather can be predicted when the cold front meets the air over the warm
pantera1 [17]

Answer:

When a cold front moves from the ocean to a warmer land it can be predicted that the meeting of the two creates storm weather, due to the formation of an occluded front.

Explanation:

Cold fronts are generally due to the passage of a cold air current over places where the temperature is warm, being denser and faster.

When an oceanic cold front meets the warm temperature of the coast, the cold air pushes the warm air upwards, creating a low pressure system and the consequence is the formation of clouds and precipitation in the form of a storm.

<em>The collision of a cold front with a warm front forms an occluded front, which can be the start of cyclones or storms.</em>
