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:
Land breezes and sea breezes both are breezes, that is how they are similar.But they are different because one breeze is blowing from the sea to the land also called a "sea breeze",and one breeze is blowing from the land to the sea also called a "land breeze"

Answer:
a) The simple interest is $126.
b) The total money repaid after 3 years is $1526.
Step-by-step explanation:
A man borrowed money at a bank $1400 at the rate o 3% for 3 years.
a) Find the simple interest
- → S.I = Simple Interest
- → P = Principal
- → R = Rate
- → T = Time
Substituting all the given values in the formula to find the Simple Interest :
Hence, the simple interest is $126.

b) Find the total money repaid after 3 years
- → A = Amount
- → P = Principal
- → S.I = Simple Interest
Substituting all the given values in the formula to find the Amount :
Hence, the total money repaid after 3 years is $1526.
Answer:
Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition.
Explanation:
Eukaryotic metabolic regulation refers to the mechanisms by which metabolic anabolic and catabolic pathways are modulated in eukaryotic organisms. Anabolic enzymes are involved in the biosynthesis of molecules, while catabolic enzymes are involved in degradative pathways. Thus, enzymes regulate metabolic pathways by catalyzing chemical reactions at their corresponding rates of reaction. Moreover, feedback inhibition refers to those mechanisms occurring when one enzyme is inhibited by the end product of the metabolic pathway, enabling cells to regulate these products.
