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.

A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.
(Loxodonta and Mammuthus can also be reversed)
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
This statement means that evolution has happened by getting the genes of the right trait expressed at the right time to help adaptability.
Explanation:
Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.
We can conclude that all features are not adaptable some are the results of genetic drift or mutations.
In case of cheetah, the faster running genes would have been there they got expressed over the period of time for better adaptability.

CF causes thick mucus that clogs certain organs, such as the lungs, pancreas, and intestines. This may cause malnutrition, poor growth, frequent respiratory infections, breathing problems, and chronic lung disease.

Chronic coughing (dry or coughing up mucus)
Recurring chest colds.
Wheezing or shortness of breath.
Frequent sinus infections.
Very salty-tasting skin.
