Transport proteins move molecules and ions across the membrane. They can be categorized according to the Transporter Classification database. Membrane enzymes may have many activities, such as oxidoreductase, transferase or hydrolase. Cell adhesion molecules allow cells to identify each other and interact.
<span>Particles that are too large to pass through the cell membrane enter and exit the cell by Endocytosis and Exocytosis
In short, Your Answer would be Option D

A microbe that grows only at the bottom of a tube of thioglycollate medium is probably a(n) <u>obligate anaerobes</u>.
Thioglycolate broth would be a versatile enrichment and differential medium that is largely used to ascertain the oxygen needs of bacteria. Obligate anaerobes can grow because of the oxygen-consuming properties of sodium thioglycolate inside the medium.
A variety of oxygen concentrations are produced in the medium across its depth as a result of this and the diffusion of even more oxygen as from broth's surface.
Because oxygen would be poisonous to obligate anaerobes, they congregate near the tube's bottom where another oxygen level is lowest.

The answer is A. Nucleus , electrons are found in the shell/orbital, protons and neutrons are found in the nucleus :)
Answer: A. The hydrogen bonds cause water to resist a change in temperature.
Explanation:
Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.
Water has high heat of vaporization due to the presence of strong hydrogen bonds between hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.
The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.
