In biology, a single-access key (also called "sequential key", "analytical key", or "pathway key") is a key where the sequence and structure of identification steps is fixed by the author of the key. At each point in the decision process, multiple alternatives are offered, each leading to a result or a further choice. The alternatives are commonly called "leads", the set of leads at a given point a "couplet". If the entire key consists of exactly two choices at each branching point, the key is called dichotomous, otherwise it is described as polychromous (or, in false analogy, "polychotomous"). The majority of single-access keys are dichotomous.

Answer:
The correct answer would be - become cancer cells.
Explanation:
Mitosis is the procedure of cell proliferation or cell division. A cell can't live everlastingly so they either divide into two new cells through mitosis or dies. In the event that something happens to the control of mitosis, the healthy cells will separate random and these new cells, malignant growth cells, will likewise be uncontrollable. These malignant growth cells won't pass on, yet they will keep on dividing and will make tumors at some time.
Thus, the correct answer is - become cancer cells.
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.
