The right answer is B
A radiotracer is an entity composed of a carrier molecule and a detectable radioactive isotope using devices such as gamma cameras or positron emission tomography.
A radiotracer is either a radioactive isotope alone or the combination of a molecule and a radioactive isotope. In this case, it is said that the molecule is labeled by the radioactive isotope.
A radioactive isotope is an atom whose nucleus, unstable, emits radiation. It could be :
- alpha radiation consisting of two protons and two neutrons.
- a beta radiation consisting of a negative electron (beta) or a positive electron (beta +, positron).
- a gamma radiation consisting of a high energy photon.
First one - two gametes will unite during fertilization to create a diploid cell
Answer:
False
Explanation:
There are some health issues that make you not able to leave the house. So therefore you can't have a social life.
Dab most likely inhibits phosphorolysis of glycogen reaction.
<h3>What is
phosphorolysis?</h3>
- Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
- It's comparable to hydrolysis.
- A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
- It's comparable to hydrolysis.
- Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
- The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
- The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
- It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.

Answer: Yes becuase white cells help in fighting against diseases, infections, allergies and foreign particles. Just like soldiers would help in fighting off enemies. These white cells keep our body safe and healthy, like soldiers keep their own country safe.
Hope this helped you!
