Active transport requires the help of carrier proteins, or “pumps”. ... Active transport is key to the function of a cell. It helps the cell control how much of certain ions such as water, sodium, or potassium pass through the cell membrane. Without active transport, a cell would not be able to maintain homeostasis.

The recognition sites for the restriction enzymes BamHI, XbaI and BglII are G^GATCC, T^CTAGA and A^GATCT, respectively. Which en
Goshia [24]

Answer:

(C) Only BamHI and BglII fragments are compatible.

Explanation:

First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.

Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.

BamHI =  G...3'               5'...GATCC  

               CCTAG...5'               3'...G

               

XbaI =      T...3'               5'...CTAGA

                AGATC...5'               3'...T

BglII =       A...3'              5'...GATCT

                TCTAG...5'              3'...A

In bold, leave the bases that remain in single strand and must be compatible with those of the other end.

To be compatible they must be complementary bases. A with T and C with G.  

Now you can see that only BamHI fragments are compatible with those of BglII.

A specimen able to produce ATP through cellular respiration, but lacking in chloroplast. Animal or Plant and why
SpyIntel [72]

Answer:

Animal

Explanation:

Animal and plant cells both carry out cellular respiration to generate ATP molecules that store energy for cellular processes. However, only plants have chlorophyll that taps on sunlight for photosynthesis. Plants use photosynthesis to create carbohydrates that are ‘burned’ in cellular respiration for energy.
