The table that correctly identifies how the plasma membrane contributes to the maintenance of cellular homeostasis would be table A.

In table A, the function of the plasma membrane as a controller of material's entry and exit into and from the cell is correctly marked while the other functions listed are marked wrong as they should be.

The plasma membrane of a cell is selectively permeable to materials. Only materials that are needed by the cell are allowed to enter while only those that need to leave are allowed to leave.

The plasma membrane has nothing to do with ATP metabolism, catalyzing protein synthesis, or receiving signals for DNA replication.

Rains happen when the water within the atmosphere brought out by the win and will eventually fall to the place where it came into

The thing is, These mountains often blocked the water-filled with air, causing it not able to reach the place behind the mountain, which will eventually became a desert

<h3>Answer: </h3><h3 />

25%

<h3>Explanation:</h3>

Following a cross between <u>Ttbb</u> and <u>ttBb</u>, the resulting offspring would be:

TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb , TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb

To have a clearer idea, see the attached image.

Of the 16 possible combinations from this dihybrid cross, there will be:

4 tall plants with blue flowers

4 tall plants with white flowers

4 short plants with blue flowers

4 short plants with white flowers

There are 4 possible genotypic recombinations that would yield short plants with white flowers out of a possible 16, so the chance that the offspring will be short with white flowers would be 4/16 which is 1/4 or 25%

Answer:

primer

Explanation:

Most biological reactions rely on the enzyme to speed up the reaction. In the case of DNA replication, this enzyme is DNA polymerase. a; DNA is a double helix made up of two long chains of deoxyribonucleotides. ... b; a primer is used to start this process by giving DNA polymerase something to bind the new nucleotide to. just for you to see.

Which of the following is changed in a reaction by the action of an enzyme?

andrey2020 [161]

Well during an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again

Answer:

Humans and fungi have a few similarities and a few differences.

Human's and fungi have similar feeding habits.

1- They are both heterotrophic (unlike plants, algae, etc. )

This refers to the fact of generating energy by consuming elements in the ecosystems.

This means that both get energy by feeding on other organisms.

2-Humans and fungi both cannot produce their own food using photosynthesis. They are not like plants.
