Hi!
<span>I. Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
</span>
<span>II.
Both DNA, which stores genetic information and encodes protein
sequences, and RNA, which is involved in the direct production of
proteins, are nucleic acids.
Please tell me if I'm wrong.
Good Day

Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
Answer:
Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.
Answer:
The lens
It helps to focus on objects and light
