Answer:
The three concepts are summarized in the general principle called the Law of Fossil Succession: The kinds of animals and plants found as fossils change through time. When we find the same kinds of fossils in rocks from different places, we know that the rocks are the same age. Scientists look for ancestors and descendants through geologic time.

Why is it necessary to take all of the prescribed doses of antibiotics even when we are already feeling better in advance of finishing them?
It's because taking them regularly until the prescription is complete helps ensure that all of the illness-causing bacteria are killed or prevented from multiplying. If you stop taking them early, the bacteria could still be alive and be spread from person to person. On top of that, the bacteria could develop to be antibiotic-resistant!
. Cells of plant A make 120 molecules of glucose an hour. Cells of plant B make half as much glucose as plant A does. How much glucose does plant make every minute?
Answer:
1 molecule of glucose
Explanation:
plant A = 120 molecules
plant B = plant A/2
= 120/2 = 60 molecules per hour
plant B takes 1 hour to produce = 60 molecules
". ". .". 60 minutes to produce = 60 molecule
plant B takes 1 minute to produce = 60/60
= 1 molecule

Describe the theory of evolution in your own words. How does this theory relate to the principle of natural selection?
Answer:
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
Explanation:
Original Question:
Describe the theory of evolution in your own words. How does this theory relate to the principle of natural selection?
Answer and Explanation:
Evolution means the adaption of animals, plants, species, etc. This study ties in with the theory of humans being descended from other animals; specifically chimpanzees. Over the course of time, Animals are believed to adapt to the environment they live in. One common example would be giraffes. In the past, they used to have shorter necks that couldn’t the leaves in a tree. Throughout the years, many breeds tended to have offsprings that had long necks. That is why giraffes have longer necks now.

Which of these is a major difference between skeletal muscle and cardiac muscle? A.Skeletal muscle works very quickly; cardiac muscle works very slowly. B.Skeletal muscle does not fatigue ; cardiac muscle is fatigues quickly. C.Skeletal muscle is involuntary ; cardiac muscle is voluntary. D.Skeletal muscle is fatigues. muscle does not.
D.Skeletal muscle is fatigues. muscle does not.
Skeletal muscle is striated muscle-essentially the fibers slide on each other to shorten and lengthen.
Cardiac muscle is a bit of a mish-mash. It is quite contractile and has striations like skeletal muscle, but also has discs within the structure which speed the contractile process
Skeletal muscle is voluntary and will not contract unless stimulated by a nerve fiber (or an electrode). Cardiac muscle is involuntary and contracts even without nervous stimulation.

D.Skeletal muscle gets fatigued while the cardiac muscle does not.
Explanation:

Neurons in which dendritic and axonal processes are continuous and the soma lies off to one side are called.
The neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.
What is a unipolar neuron?The neuron is the structural and functional unit of the nervous system, which when they have only a short projection that later branches into two or more branches, are considered unipolar.
That is, they are those neurons in which only one extension or neurite emerges from the soma, which will act as an axon and at the same time will have dendrites with which it can both receive and transmit information.
Therefore, we can conclude that the neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.
