Answer:
HIV destroys helper T cells
Explanation:
The evading viruses destroys helper T cells or the CD4+ thus the body can no longer stop some infections. The secondary infections also called opportunistic infections are rampant with people who have AIDS. This is because helper T cells help fight against most infections in the body.
Answer:
A. 22.85 mL of oxygen
Explanation:
Data:
The total volume of Oxygen =500 mL.
Percentage of Oxygen inhaled= 20.94 %
Amount of Oxygen inhaled =20.94 /100 x500 ml
=104.7 ml
Percentage of Oxygen exhaled = 16.37 %
Amount of Oxygen inhaled =16.37 /100 x500 ml
=81.85 ml
Difference b/w amount of oxygen inhaled/exhaled= 104.7 ml-81.85 ml
=22.85 ml
Therefore, Option A is correct option.
Hope it help!
Answer:
B) Helicase uses energy from ATP Hydrolysis
Explanation:
Helicase's primary function is to separate the annealed nucleic acid strands. It is a motor protein and moves directionally along the phosphodiester backbone. It usually separates strands of double helix DNA or self annealed RNA. It used the energy from ATP hydrolysis and breaks hydrogen bonds between nucleotide bases.
In human body 95 types of helicases are found. They have sequence motifs required for ATP binding, ATP hydrolysis and translocation along nucleic acid phosphodiester backbone. The variable portion in their amino acid sequence imparts specific feature to each helicase.
Answer:
A
Explanation:
A gene holds the instructions that forms the proteins in our bodies and these proteins are used for our traits and bodies.
