The answer is A. DNA is the genetic code that eventually gets transcribed into RNA and that RNA is then translated into protein chains (polypeptides). Thus the ultimate purpose of DNA is to build these proteins.
B is wrong because while DNA itself exists in a double helix, its main function is not to build other double helix models. In fact, RNA exists in single helix form.
C is wrong because the brain does not construct the body.
D is wrong because DNA is just a body of information, and not a historical record.
Answer:
m<B = 83°
Explanation:
The figure given is a parallelogram having opposite sides that area parallel to each other. Therefore, opposite angels are congruent while the adjacent angles are supplementary.
<A and <B are adjacent angles. Therefore,
m<A + m<B = 180°
97° + m<B = 180° (substitution)
m<B = 180° - 97
m<B = 83°
Answer:
A. Magma rises from the mantle.
Answer:
Plants absorb water from the soil with the help of roots. It also absorbs minerals in organic form through root hairs. The water and minerals get transported by xylem vessels. ... - Another pressure called root pressure is also important as it is exerted by the root due to its metabolic activities.
