Biologists are the people who study and research about most of the things that are related to living things, including plants, animals, bacteria etc.
Example of topics they study include "ecology", like how different living organisms relate and interact with each other, or "cell biology", with small topics like how protein synthesis works or what is DNA or RNA.
Area of scientific studies that usually fall outside biology includes "astronomy" the study of space, or" chemical bondings", like how does elements react with each other.
Answer:
symmetrical in many ways across a central axis" and "presence of a head".
Explanation:
Bilateral symmetry is a characteristic that many organisms has at which if we divide the body using an imaginary line, we will see two mirror images. Two characteristics that an organism with bilateral symmetry possess are symmetrical in many ways across a central axis (known as well as the sagittal plane), and presence of a head that is at the middle of the central axis. The great majority of organisms posses bilateral symmetry, including the humans.
Answer:
Explanation:
If DNA is not accurately replicated it can lead to mutation. Mutation is a genetic disorder that occur when a change occur and affect the genome of an organism. It can be result in frameshift mutation shifting nucleotide arrangement.
When DNA is not accurately replicated, it could lead to formation of an entirely new protein different from the original which has a different function this could lead to a form of disorder in the offspring. The effect of this disorder depends on it severity.
