Natural selection is a type of selection that exists between certain inherited conditions and environmental pressures.
How does malaria and sickle cell anemia show natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. Natural selection is a non-random difference in reproductive output among replicating entities.
It turns out that HbS carriers have been naturally chosen in these regions because the trait gives some malaria resistance. When they are infected with the malaria parasite, their red blood cells, which include some aberrant hemoglobin, have a propensity to sickle. The malaria life cycle intensifies both natural selection and random genetic drift.

Suppose a mouse develops loss of sodium pump activity in the thick ascending limb of the loop of henle in all of the nephrons in both kidneys. What problem would you expect this mouse to have?.
The problem that we would expect this mouse to have is a tendency to drink more water than normal accompanied by excretion of dilute urine.
What is Sodium Potassium pump?The sodium-potassium pump is a protein that has been found in many cells and is responsible for keeping the internal concentration of sodium ions [Na+] lower than that of the surrounding medium (blood, body fluid, or water) and the internal concentration of potassium ions [K+] higher than that of the surrounding medium (blood, body fluid, or water). The adenosine-triphosphatase (ATPase)-active pump travels across the cell membrane and is triggered by both internal and external [K+] and [Na+].

The correct option is B. It regulates body temperature.
What is homeostasis?In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range). Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms. All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.To learn more about homeostasis, refer:

A daughter cell that matures to the inside of the vascular cambium becomes secondary xylem and a daughter cell that matures to the outside of the vascular cambium becomes secondary phloem.

In a stressful circumstance, adrenaline is immediately released into the blood, sending signals to the organs to trigger a certain response, within a few minutes.
Depending on the sort of cells it is working upon, adrenaline has a wide range of diverse effects. However, adrenaline's general impact is to get the body ready for the "fight or flight" reaction under stress, that is, for quick and/or forceful action.
Key effects of adrenaline include speeding up heartbeat, raising blood pressure, widening the pupil of the eye, lessening pain sensitivity, improving vision, hearing, and other senses, slowing digestion, rerouting blood to the muscles, and changing the body's metabolism to maximize oxygen and nutrients to the body and raise blood glucose levels.

Bladder cancer (BCa) is an endocrine-related tumor and the activation of androgen signaling pathways may promote bladder tumorigenesis.
Abstract:We compiled the research on the effects of altering androgen signaling pathways on Bladder cancer therapy outcomes, both preclinical and clinical. A thorough analysis was done in December 2020. The following criteria were met by the papers we included: examining the effects of androgen signaling regulation on the results of Bladder cancer treatments through innovative preclinical and clinical studies. Eight clinical trials and six preclinical studies were found. Preclinical research shows that the activity of radiation, doxorubicin, cisplatin, gemcitabine, and the Bacillus Calmette Guerin may be affected by the modification of androgen receptor-related pathways.
Patients receiving treatment with 5-ARIs or androgen deprivation therapy (ADT) have a considerably lower relative risk of developing Bladder cancer again after transurethral resection of the bladder tumor (TURBT) (Relative risk: 0.50, 95 percent confidence interval: 0.30-0.82; p = 0.006). In patients using 5-ARIs, subgroup analysis showed a relative risk of BCa recurrence of 0.46 (95% CI: 0.22-0.95; p = 0.040). The ratio of T1 Bladder cancer patients in treated/control groups and the relative risk of BCa recurrence were found to be significantly negatively correlated. A promising technique to lower the recurrence rate of Bladder cancer, particularly in patients with early-stage disease, may involve 5-ARI therapy.
