Most molecules share a covalent bond. This means that they share electrons with two atoms. The electrons that they share form a new circle that extends around the nucleus of each atom, which is what makes up a molecule. Happy to help. Have a Great Day!
Answer: They are heated up and turn into magma, then they are cooled and crystalize.
Explanation:
Answer:
Cyclic forms
Explanation:
The hydrates of carbon are called carbohydrates. Carbohydrates are known as saccharides. The simplest carbohydrates are the monosaccharides such as glucose, fructose. Monosaccharides are the units of polysaccharides such as starch, cellulose. Polysaccharides are long chains of monosaccharides joined by glycosidic bonds in cyclic form. The glucose molecules in polysaccharides are linked in the cyclic form. It is formed when the hydroxyl group on carbon 5 linked to the aldehyde carbon 1 .
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.
It relates to the meaning of the pores of skin because it lets in and out only certain things.
I hope this helps, Sweetie.
