Answer: Option A and E.
Explanation:
Norther hemisphere Is the half of the Earth that lies on the north of the equator. The equator is the line that divide the Earth into two halves.
During the winter, the northern hemisphere is colder because the northern hemisphere move away from the sun and receive less sunlight form the sun. The sun is very high in temperature and it has high heat, when the northern hemisphere move away from it, there is lower heat or temperature that get to it , making it to become cooler or have lower temperature. The countries in the northern hemisphere comprises of all countries in Europe, North America, Asia,part of South America and little part of Africa.
The correct answer is option (C) transposons or jumping genes.
Barbara McClintock was an american cytogeneticist. In 1940s, she discovered the phenomenon of transposition brought about by the mobile genetic elements or jumping genes or the transposable elements. These jumping genes refers to a sequence of DNA which can change its position in the genome or the genetic constitution of an organism. She discovered these jumping genes in the Maize for the first time and received the nobel prize in 1983.
Jumping genes form a major portion of the eukaryotic genome. They are often responsible for mutations and associated with the duplication of the genetic material. They also cause the structural changes in the chromosomes like inversion, deletion and translocation which are called the chromosomal aberrations.

Answer:
Structures that are still present but currently serve little to no purpose
Explanation:
<em>Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.</em>
Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the <u>caudal vertebrae</u> found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.
<u>Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.</u>
