Serga [27]

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.

The fruit fly Drosophila melanogaster is an important model system for studying inheritance in animals and genetic control of an
Snezhnost [94]

Answer:

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.
