State 2 features each which viruses have in common with living things
BabaBlast [244]
1. Like living things, viruses have genetic material and 2. viruses can evolve.


- Viruses share many genes with their host cells. Viruses are dependent on living organisms, which lead to some living characteristics - they can reproduce/replicate in living host cells, mutate, appear in different strains, and have unique genetic material. However, viruses are classified as not living things because they can’t carry out the necessary processes that meet all requirements for the classification of a living thing. They do NOT undergo respiration and cannot generate energy needed to survive on its own, but viruses *do* share a few features with living things.

Ilya [14]

The student who caught the cold caused by this specific Rhinovirus was exposed to the exact same Rhinovirus 18 months later. Memory B cells of the immune system will protect her from getting the same cold again.

In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centres of the secondary lymphoid organs.

Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. Their function is to memorize the characteristics of the antigen that activated their parent B cell during initial infection such that if the memory B cell later encounters the same antigen, it triggers an accelerated and robust secondary immune response.

Memory B cells have B cell receptors (BCRs) on their cell membrane, identical to the one on their parent cell, that allow them to recognize antigen and mount a specific antibody response.

Answer:

D

Explanation:

The correct option would be D.

12 - 2 would give +10

-5 + 5 would give 0

-5(-2) would give +10

24 - 34 would give -10

Hence, options A, B, and C are incorrect because they give figures that deviate away from -10. <u>The only option whose operation results to -10 is D.</u>
