This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>
Answer:
A) Passive transport
Explanation:
The answer for the question is A
DNA and RNA are polymers composed of nucleotides.
<h3>What are polymers?</h3>
Polymers are large complex molecules that consist of small, simple parts that are linked together by chemical bonds. The small and simple parts of polymers are called monomer units. Hence, polymers are formed from monomers.
DNA and RNA are nucleic acids that are formed from nucleotides. In other words, DNA and RNA are polymers whose monomers are nucleotides. The nucleotide bases of DNA and RNA include the purine bases (Adenine and Guanine) and the pyrimidine bases (cytosine and thymine or uracil)
Polymers like DNA and RNA can be broken down by removing the bonds between monomers to give their monomer units.
