Answer:
With millions of different kinds of organisms in the world, scientists must find order in all of this diversity. Scientists group living organisms into one or more of a few major categories as part discipline known as taxonomy. The bodies of organisms are organized into functional systems—cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation. All living things on Earth are composed of the same carbon-based, molecular building blocks.

Answer:
The correct answer is: B) codominance.
Explanation:
<u>Codominance is a type of inheritance pattern that describes the relationship of two variations of the same gene</u>: this means that in an individual, its two alleles manifest in the phenotype.
If a sunflower has both blue AND yellow speckles, it means that the two possible alleles are in a relationship, which makes these alleles CODOMINANT.
The basis of the process of Natural selection is the random mutation: some organisms develop random mutations which increase their chance for survival and they survive more likely than other organisms and reproduce.
So the correct answer is:
A) Through random mutations in DNA, some pests developed a resistance to the pesticide.
