Answer:
Active transport necessary for the sodium-potassium pump to work because It allows sodium and potassium to move against their concentration gradient.
Explanation:
The transport of sodium ions outside the cell and potassium ions inside the cells is called active transport that requires the ATP hydrolysis. ATP provides the energy required for this procedure. This sodium-Potassium pump works to move the ions against their concentration gradient to keep the sodium concentration low inside the cells and potassium concentration high inside the cells.

Answer:
The correct answer is option A) "cause iron in ocean water and terrestrial rocks to rust (oxidize)".
Explanation:
During ancient times, the reproduction success of plants and cyanobacterias led to the accumulation of oxygen gas in the atmosphere. One early consequence of this accumulation was the oxidation of the iron in ocean water and terrestrial rocks. This phenomenon is the cause of banded iron formations, which formed in seawater and sank to the ocean bed.
Answer: The building blocks of proteins are amino acids, which are small organic molecules that consist of carbon atoms linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Translation:
Los componentes básicos de las proteínas son los aminoácidos, que son pequeñas moléculas orgánicas que consisten en átomos de carbono unidos a un grupo amino, un grupo carboxilo, un átomo de hidrógeno y un componente variable llamado cadena lateral.
