Answer:
Here's Why:
Explanation:
In living cells there are hundreds of different enzymes working together in a coordinated manner, and since cells neither synthesize nor break down more material than is required for normal metabolism and growth, precise enzyme regulation is required for turning metabolic reactions on and off.

Answer:
Concentration gradient
Explanation:
Concentration gradient of the ions across the membrane generates the membrane resting potential.
Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
The answer is penicillin
Rheumatic fever is a disease that caused by Group A streptococcus infection. The bacteria has component that similar to the heart valve cells, makes the immune cell attack it. The drug of choice for this infection is penicillin G benzathine injection. It is one of penicillin family drug that has high prevalence of allergy reaction, so you must be aware.
Answer:
AA
Explanation:
Just like the ABO alleles, each biological parent donates one of their two alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).
