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.
Answer:
c. because arteries carry high pressure blood from the heart
Explanation:
Arteries carry the oxygenated blood that is pumped directly from the left ventricle of the heart. Since they receive blood from the heart, the blood pressure is higher in arteries than veins. To withstand the higher pressure of blood pumped by heart, arteries have thicker walls than the walls of veins.
Answer:
The correct answer is They both contain carbon ,but only nucleic acid contain phosphorous
Explanation:
Carbohydrates are also called polyhydroxyaldehydes or polyhydroxyketones.Carbohydrates contain carbon,hydrogen and oxygen.For example glucose(C6H12O6).
On the other hand nucleic are composed of nucleotides that contain nitrogen base,ribose sugar and phosphate group.
The presence of phosphate group in the nucleic acid make it different from carbohydrate.
