Dna damage can occur as a result of exposure to chemicals or ultraviolet radiation. This is what happens during nucleotide excision repair of damaged dna. A multienzyme complex crosses the DNA in search of distortions in the double helix, once located, the phosphate skeleton of the affected chain is cut on both sides of the altered region, a helicase eliminates the oligonucleotide resulting from digestion, the "Gap" "is filled with a DNA polymerase and a ligase.

A memory B cell is kinda of how it sounds it has a memory of what your body has fought before such as a virus and can stimulate a response quicker then the first time you encountered it. 

If you lack memory B cells your body doesn't built up the same immune response when you come into contact with the virus again.

"Vaccination would prevent further disease" Incorrect, a vaccine lets you build up memory cells to combat the disease if you lack them you cannot build up a defense.
"Vaccination would not prevent further disease" Correct, a vaccine can be a dead version of a virus or parts of a virus that shows your body what to respond to quickly in the future. If you body cannot make memory b cells it wouldn't help to use a vaccine. Your body wouldn't keep a memory of it being bad.
"You would not produce antibodies" Even if your body does not remember a particular virus it does produce antibodies to combat it just not as quick or efficiantly as something it has come into contact with before and produced memory cells.
"You would over produce histamine" Incorrect, different process for that histamine.

Which reactant of photosynthesis is also involved in climate change?
choli [55]

Answer:

B. Carbon dioxide

Explanation:

First of all, let’s write out the photosynthesis equation to identify the products and reactants.

6CO2 + 6H2O + energy —> C6H12O6 + 6H2O

In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.

In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.

Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.

We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.

Therefore, the best answer choice is B. Carbon dioxide
