A Paramecium has an internal sucrose concentration of 0.040 M, a glucose concentration of 0.035 M, and a fructose concentration
Nadusha1986 [10]

Answer:

<u>c. Sucrose and glucose</u>

Explanation:

The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.

Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

True or false: in the sequence aggcct, an available phosphate group would be found at the 5' end of the nucleotide labeled "t."
Oksanka [162]

The answer is false.

an available phosphate group would be found at the 5' end of the nucleotide labeled A. The 5′-end of a DNA contains a phosphate group that is  attached to the 5′ carbon of the ribose ring and that A phosphate group  permits ligation of two nucleotides ( phosphodiester bond).
