Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
- <em>Adenine is complemented with Thymine A=T</em>
- <em>Guanine is complemented with Cytosine G=C</em>
From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
<em> A + C = G + T</em>
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
<em> A + C = G + T</em>
<em> 5 + 7 = 7 + 5</em>
The biome that has over 100 inches of rain each year is the Rainforest. Therefore, the Rainforest has abundant rainfall.

Answer:
The axial skeleton includes all the bones along the body's long axis. ... The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.
Explanation:
Answer:
Transboundary
Explanation:
Transboundary refers to a highly contagious disease that has the potential to spread extremely rapid irrespective of national boundary. They cause high mobility and motility in the susceptible animals. An example of such diseases include Avian Influenza and the African Swine flu.
Zoonotic disease is disease that can be transmitted from animals to Humans example anthrax.
Exotic disease refers to a disease that does not normally occur in a particular region
Emerging diseases are those that have recently appeared and are cases are rapidly increasing.
Epizootic are those that appear in a large number of animals in the same place at the same time
