The nervous system: In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.
The circulatory system: The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
The respiratory system: The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
The muscular system: The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles can be completely autonomous.

Answer;
-Evolution by natural selection
-The theory of evolution by natural selection states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.
Explanation;
-The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.
-Natural selection is the phenomenon that some traits confer a reproductive advantage (fitness), resulting in (a statistical expectation of) that trait increasing in the population over time (evolution).
Answer:
Enzymes unwind the DNA molecule into two strands.
Explanation:
I just took the quiz and it was correct
The father of this offspring should be male 3. It is the only individual that exhibits certain molecular genetic markers present in the offspring but absents in the mother.
<h3>Genetic markers</h3>
A molecular genetic marker is a fragment of DNA that can be used to trace the inheritance pattern from parents to offspring.
In this case, parents and offspring exhibit three molecular markers which are shared among them.
There are certain genetic markers that are present in the offspring but they are absent in one of the parents, and therefore they can be used to trace the inheritance pattern.
