The answer is pilus. This structure joins two bacteria of same species and allow exchange of genetic material in a process called horizontal gene transfer (conjugation). The plasmid of one of the bacteria (the mobile plasmid) is nicked once and the strand moves through the pillus to the other bacteria. It combines with the other plasmid or chromosome to for recombinant dna.
Answer:
A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. ... Each of these elements is circulated through the biotic components, which are the living parts of an ecosystem, and the abiotic components, which are the non-living parts.
Answer:
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’s response to its environment.
Answer:
The correct answer is option d. "phosphorylation of glucose".
Explanation:
The phosphorylation of glucose is one of the most important catabolic reactions that allow to obtain energy from sugars. This reaction is the first step of glycolysis and avoid cells to lose sugars by diffusing back to its transporter. The phosphate used to phosphorylate glucose comes from the hydrolysis of one of the three phosphate of adenosine triphosphate. Therefore, phosphorylation of glucose is a processes where ATP hydrolysis is directly involved.
