Answer:
Mutations affect evolution by increasing genetic variation and the potential for individuals to differ.
Enzymes speed up all of the reactions that happen inside cells. They help with digestion and our metabolism. Enzymes can do a few different things like:
Break up big molecules into smaller pieces, so they can be absorbed more easily by the body.
Enzymes also are very picky catalysts, and will only “speed up” certain types of reactions.
Hope this helps you!! (:
I can tell you that it is NOT B.
I got it wrong.
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.
The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.
Answer:
True
Explanation:
Conjuctiva is that thin transparent mucous membrane that covers both the anterior surface and the inner surface of the eyelid. Conjuctiva is an important component of the eye that keeps the inner surface of the eyelids and the front surface of the eye moist and lubricated. It also helps protect the eye from foreign particles and from infection.
The part of the conjunctiva that covers the eyelids and is reflected over the anterior surface of the eyeball is called the bulbar conjunctiva. The part that is found coating the inner surfaces of the eyelids is called the palpebral conjunctiva.
