Answer:
B.
Explanation:
Because if they have traces of RNA in them, then it might be the first genetic material
The correct answer to this question is B. Some members of the Fugate family had a genetic condition called methemoglobinemia, that gave a blue color to their skin. The gene causing this disease is an autosomal recessive gene, so to have this condition you need to be homozygotes for this recessive gene. Gene flow was prevalent in the Fugate family since not all of the children had blue complexion, but only four of them. The three children that did not have blue complexion, had the dominant allele, probably through gene migration from another population nearby. Also, since it is easier nowadays to travel, two separate populations could meet more easily. This increases the incidence of gene flow and explains the reduction of the occurrence of the condition.
Generally, temperature increases. as altitude increases ! <span>However, the temperature increases with altitude in some layers. This is called an inversion. Inversions can appear at any altitude in the troposphere.

Animals are associated with <u>phyla</u> and plants are associated with <u>divisions</u>
Answer: Option B
<u>Explanation:</u>
There are millions of organisms in the world. They were then subdivided based on the similarity between each groups.
The Animal kingdom range from complex to simple animals. The kingdom Animalia is further subdivided into Phyla. The phyla is further classified into vertebrates and invertebrates.
Plants acquire nutrition by photosynthesis. They are autotrophs preparing their own food. Animals can’t prepare their own food hence they directly or indirectly depend on the plants for food. The plant kingdom is subdivided to plant divisions.
