Jose and Karl were both exposed to the influenza virus at work. Jose had a flu shot made from killed influenza virus six weeks a
go, but Karl has not gotten around to getting his vaccinations yet. Are they likely to get sick from this exposure to the virus, and what is likely to happen if they are exposed to it again? Both Karl and Jose are likely to get sick this time since Jose's vaccine was dead, but neither will get it again once they acquire active immunity.
Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.
Karl will get sick and Jose will not this time, but Jose will be more likely to get it later since his immunity will be less recent than Karl's.
Both Karl and Jose will get sick this time since Jose's immunity has had time to wear off, but Karl is more likely to get it again since he has only been exposed once.
The correct answer is Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.
In the case of Jose artificially active immunity has been induced due to vaccination. A vaccine instigates a primary response against the antigen without resulting in any signs of the disease. On the other hand, Karl will acquire active immunity naturally in future, as when an individual get exposed to a live pathogen, he or she develops the disease, and turns immune as an outcome of the primary immune response.
Enzymes speed up the chemical reactions in living cells.
Explanation:
An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
Homozygous dominant is when 2 dominant alleles are present. Solve the punnett square and whichever boxes have 2 dominant (uppercase/capitalized) letters in it are homozygous dominant
I cannot read the letters on your picture very well, I'm sorry.
