Answer:
A. decreases
Explanation:
Since gravitationalforce is inversely proprtional to the distance by the formular F = GM1M2/r^2.
Answer: is D. Mercury was used to treat many illnesses long ago, and after being deemed safe by modern doctors its use has increased in the past 100 years.
Explanation:
Answer: The correct answer for the fill in the blank is ATP.
ATP ( adenosine triphosphate) is considered as the energy currency of the cell. The energy captured from the food by the living organisms is stored in ATP. It a high energy containing molecule. The energy is stored in its high energy chemical bonds, called as phosphoanhydride bonds ( between phosphate molecules).
Whenever the body requires energy, hydrolysis of ATP takes place ( ATP is converted to ADP and inorganic phos[phate). This results in the release of the stored energy.
Thus, most potential energy captured from food molecules is stored as ATP.
A. do so on membranes called thylakoids.
Answer:
A protoplanetary disk is round rotating object which is made of dense gas. This surrounds the newly formed star, Herbig star and T tauri star.
It is also considered as a accreation because the remnants like gases and other materials fall from them on to the star.The extremely illuminating protoplanetary disk are known as the proplyds.
Whereas the nebula can be defined as the densely packed hydrogen and other gases that collapse under the force of gravity. The Nebula starts becoming smaller and smaller because the particles of gases collapse and get closer to each other.
Upon force of gravity their friction and heat increases which slowly collapse the star.
