Answer:

That person would need thousands of calories a day.

Explanation:

The ideal amount of daily calories is different for each individual. Factors such as height, age, gender, muscle mass, daily activities, etc. influence the basal caloric expenditure of the organism. However, the number of calories a person needs to consume per day is always measured over one thousand calories. That is, no matter if you live in England or Africa, that person will need to consume thousands of calories a day to stay healthy. Usually the ideal amount of calories a person in normal health should consume is around 2000 - 2200 calories per day.

A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium  concentration.

<u>Option: A</u>

<u>Explanation:</u>

Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.

The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.

<h3>What is smallpox?</h3>

Variola major or Variola minor are the two virus strains that cause the contagious sickness known as smallpox. The variola virus (VARV) agent is a member of the genus Orthopoxvirus. The World Health Organization confirmed the illness's universal eradication in 1980 after the last naturally occurring case was diagnosed in October 1977, making polio the only human disease to have achieved this feat.

Fever and vomiting were among the disease's earliest signs. This was followed by the development of mouth ulcers and a rash. The skin rash developed into the typical fluid-filled blisters with a dimple in the middle over a period of days. The scars were left after the lumps scabbed over and dropped off. People could contract the illness from contaminated things or from one another. Prevention is through the vaccine for smallpox.
