Answer:
The most common example of a molecular pump in the human body is the pump for sodium and potassium.
Explanation:
Sodium ions and ATP bind to the pump to use energy to change the shape. The sodium then leaves and the potassium can now bind due to the shape change. The potassium ions are then released and the pump goes back to normal for the cycle to repeat again.
Answer:
Nucleic Acids
Explanation:
Nucleic acids link together to form DNA, which determines the different traits people have, directly relating to appearance.
The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.
Answer:
Explanation:Population genetics is the field of biology that studies allele frequencies in populations and how they change over time.
Answer:
The statement is true.
Explanation:
The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.
