<span>Vitamin K clots the blood and stops excessive bleeding. There is a blood disorder called vitamin K deficiency bleeding (VKDB). It is thought that newborns do not get enough vitamin K from their mothers so this injection could prevent VKDB from developing.</span>
I think your answer is c. Correct me if I am wrong, but I simply subtracted 2081 minus 1997, and got 84 years.

Explanation:
Were viruses ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Answer:
D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
Explanation:
Active transport refers to the movement of molecules across biological membranes against a concentration gradient. Active transport can be divided into 1-primary active transport, which requires energy from the hydrolysis of adenosine triphosphate (ATP); and 2-secondary active transport, which requires an electrochemical gradient generated by pumping ions in/out of the cell. The case above described represent a type of secondary transport active because the movement of sodium (Na) ions is used as energy source to move glucose molecules against their concentration gradient.
