Answer:

Plasmids are used in biotechnology.  

Explanation:

A plasmid is a natural or artificially modified circular DNA molecule for use in biological research.

The researchers use the plasmids to insert a DNA fragment of interest, thanks to the cloning cassettes. They can clone genes to express proteins or RNAs and analyze them.

Answer:

A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms

Which of the following serves as an electron carrier in cellular respiration?
GrogVix [38]

Answer;

-NAD+

Explanation;

-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.

-NAD+ and FAD; also the two most common electron carriers in the body. NAD+ can accept a pair of electrons (and a hydrogen ion) to become NADH.

k0ka [10]

Answer:

WATER REABSORPTION IN THE COLLECTING TUBULE OF TE KIDNEY

Explanation:

Antidiuretic hormone synthesized by the neurons in the hypothalamus and the posterior pituitary allows for the reabsorption of water from the collecting ducts of the kidneys back into the circulation.

This therefore reduces the amount of water in the urine causing the formation of concentrated urine and reduced volume of urine.

It causes the increased reabsorption of sodium in the ascending loop of Henle adding to the counter-current mechanism which aids the further reabsorption of water from the distal tubules and collecting ducts.

It also allows the constriction of arteries thereby reducing arterial blood pressure.

QveST [7]

Answer:

24 million years

Explanation:

A: GCACTAAGCATCGATTT

B: GCACCAGGCACTGGTTC

There are 6 base pair changes between species A and species B. Since we know the rate of change is 1 base pair every 4 million years, we know 6x 4 million is likely how long ago the species diverged. 6x 4 million = 24 million years
