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.

You are dispatched to a​ 1-year-old child with respiratory distress. En​ route, you review how to assess and treat infants with
Anastasy [175]

Answer:

B. Mental status

Explanation:

Respiratory diseases are medical conditions that affect the lungs and breathing capacity, but do not alter the child's mental state, so in assessing the child's breathing, it will not be necessary to evaluate breathing work, chest expansion and sounds of the child's breath. It is not necessary to evaluate the mental states to know if the child has breathing problems.

Some breathing problems are genetic while others are caused by lifestyle or environmental factors. Common breathing problems include asthma, bronchitis, emphysema, tuberculosis and sinusitis.

1. Compare and contrast the functions of DNA and RNA.
xz_007 [3.2K]

Answer:

  • compare and contrast
  • DNA replication works
  • process of transcription

Explanation:

COMPARE AND CONTRAST:

DNA is a double-stranded molecule while RNA is a single-stranded molecule. DNA is stable under alkaline conditions while RNA is not stable. ...DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine

HOW IT WORKS:

How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

PROCESS OF TRANSCRIPTION:

Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the maintranscription enzyme. Transcriptionbegins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).
