People are often able to live in a coma for several years because parts of the body that are not under conscious control continue to function. This situation best reflects the importance of the

A) central nervous system

B) autonomic nervous system

C) somatic nervous system

D) forebrain

Answer:

B) autonomic nervous system

Explanation:

The autonomic nervous system is a part of the peripheral nervous system. It comes under the motor division of the peripheral nervous system. The function of this division of the nervous system is to deliver the motor information from the central nervous system to the smooth muscle, cardiac muscle, and glands.  The responses produced by these muscles and glands are not controlled by the will or conscious of the individuals.  

Due to the functioning of the autonomic nervous system, the person under the coma could perform the activities such as breathing, pumping of heart to deliver the oxygen to the body cells, etc. and stay live.

A scientist used radiation to change the mutation rates of a population of bugs. He then measured how many generations it took f
Papessa [141]

For this experiment, artificial selection is made by the scientists where traits of benefit are made to be present in the gene by high mutation rate so that the adaptability increases.

Explanation:

Natural selection is a process by which a organism with beneficial traits survive and reproduce in large numbers. They adapt to the environment very quickly and pass on these traits to its progeny which are at the better survival zone.

The mutations for the beneficial traits in certain genes caused the bugs to adapt to their environment well. When mated, they pass on the traits in every generation. It is also said that those organisms who did not get mutated eventually died.

The faster the mutation rate, the faster the mutated bugs with beneficial traits will appear in each generation.

From the graph it can be said that those bugs who could not bear the mutation they died and hence did not appear in the next generation only those bugs who could cope up the environment survived.

Four students provide their teacher with an explanation of why photosynthesis is considered a chemical change. Luke: Photosynthe
kenny6666 [7]

Answer:

The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".

Explanation:

A chemical change is one which is not easily reversible and which results in the formation of new subsatances.

For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.

From explanations provided by the students :

Luke does not give any explanation of the process but only an observation

Jackie's explanation does not state the main reason why a chemical change differs from a physical one.

Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.

Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
