Active Transport is the answer

4 0

Answer:

The correct answer is option B, that is, active transport.

Explanation:

In order to move a substance against an electrochemical gradient or concentration gradient, a cell needs energy. Thus, for this a cell follows active transport mechanisms, for this, energy is expended in the form of ATP in order to sustain the appropriate concentrations of molecules and ions in the living cells.  

The active transport refers to the phenomenon in which the movement of molecules or ions takes place through a cell membrane from the region of lower concentration to a region of a higher concentration, facilitated by the enzymes and the process requires energy in the form of ATP.

WILL MARK YOU THE BRAINLIEST!!!!!!!!!!!!!!!What is DNA Sequencing? And how is the procedure done. IN YOUR OWN WORDS!!!!!
lesantik [10]
Alright, so DNA sequencing is the process of determining the sequence of nucleotides, or basically the order of them. The nucleotides are adenine, guanine, cytosine, and thymine, AKA: <span>(As, Gs, Cs, and Ts)

Let me explain: All strands of DNA have a specific construction of nucleotides, which basically form the structural unit of DNA.

DNA sequencing is a process of identifying those nucleotides and how their composition is. It's determined through the use of various methods and technologies. 

If you've ever seen a chart involving dozens of C's, T's, A's, and G's, then that's a model of the nucleotides.

Wat biotic and abiotic factors control viral activity in the sea
disa [49]
The answer is;
  1. Biotic – planktons
  2. Abiotic -  temperatures

A biotic factor that affects viral activity is planktons and bacteria in the sea. Viruses insect bacteria, planktons and use their machinery to replicate themselves. Viruses, therefore, lyse and kill many bacteria in the seas and make carbon available in the oceans-  hence drive the carbon cycle.

Temperature is an abiotic factor in the sea that affects viral activity. Higher temperatures or too cold waters will reduce viral activity in the oceans and seas.

Which rights allow an individual to assign use rights or management rights for a resource? rights allow an individual to assign
tankabanditka [31]

The answer is: Use right / the right to use

Use right could only exist if a person who own a certain property or resources willingly (without any threat) give permission to other people to use that property/resources.

In business environment, this type of rights mostly given for artistic products. For example, in order to input a music that you didn't create on your you tube video, you need to obtain the use right from the artist who created the music.
