Answer:
The correct answer is Single Circular DNA Molecule.
Explanation:
A bacterial genome, which is the DNA that is found in bacteria collectively, is a double stranded circular DNA. So it has no start and end like double stranded helix DNA. The option D, which is "Single Circular DNA Molecule" is correct.
I hope this answer helps.

Answer: Option A.
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
Explanation:
countercurrent multiplier is a system that utilize energy that create osmotic gradients and enable reabsorption of water thereby increase concentration of urine. The countercurrent multiplier uses electrolyte pumps there by making the nephron loop increase the concentration of salts in the interstitial fluid of the kidney medulla because it allows the nephron to reabsorb alot of water and and increase the concentration of urine for excretion while at the same time using as little energy as possible.
Motor proteins move chromosomes along the kinetochore microtubules as they become shorten by depolymerizing at their kinetochore ends. Motor proteins at the spindle poles move in the chromosomes with the microtubules depolymerizing at the poles. As the animal increase in length, the spindle poles extend away from each other. This pulling away is due to overlapping nonkinetochore microtubules moving away from each other using motor proteins.,
