The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family
<h3>What is taxonomic classification?</h3>
Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.
The hierarchical arrangement of the taxon are as follows:
- Kingdom
- Phylum/Division
- Class
- Order
- Family
- Genus
- Species
These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.
This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.

Answer:
See explanation
Explanation:
Darwin proposed his theory of evolution on the premise of natural selection. According to him, organisms which possess favourable characteristics which enable them to survive in their environment are more likely to survive and reproduce, passing on these favourable characteristics to their offsprings.
According to Mendel, the unit of inheritance passed on from parents to offspring are genes. Hence Darwin's factors are Mendel's genes.
If Darwin knew of Mendel's work. It might have influenced his presentation of the idea of passing on favourable characteristics from parents to offspring in the light of genetics.
This would have made Darwin's work to have more empirical backing hence making it more widely accepted.
If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.
<h3>What is the Cas9 gene?</h3>
- Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
- Its main function is to cut DNA and thereby alter a cell's genome.
- Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.

Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.
<h3>
What is competition?</h3>
If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.
As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."
