If there are only two options and you did not just accidentally put C and D then I would believe that the answer is A: Monosaccharide and disaccharide.
Answer:
Viruses are composed of one or more cells.
Explanation:
The viruses are microorganisms composed of genetic material protected by a protein envelope, and that´s how they work and live. This protein membrane, (only present in some viruses), is carbon based.
By they way of fuction, they evolved along whit the cell in wich they are introduced, since they reproduce with it.
<span>This is true. Pioneer species are introduced to infertile soil so that the soil may become suitable for growing other plant species. These species do not rely heavily on soil; instead, they live on rocks and minerals. Moreover, they break down these rocks into soil so and eventually create a thicker layer of soil, allowing other plant species to inhabit the same region.</span>
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
The answer for this question would be choice <span>B) Water, rock, and surface materials, or the second option.</span>
