Answer:
According to the cell theory cell is the structural unit of all living organisms and viruses cannot be considered as living organisms according to this theory
Explanation:
Viruses are not made up of cells and they only contain genetic material like RNA or DNA. since viruses are not made up of cells they do no fit the classification of living organisms. To define living organisms other criterion like reproduction, maintenance of homeostasis and ability to adapt to the external environment are mentioned in the cell theory.
Viruses have the ability to replicate and adapt to even extreme conditions of their environment which makes the question of classifying viruses in the category of living organisms even more complicated.
Similarities and differences are explained below
Explanation:
Differences:
somatic nervous system:
- It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
- It has sensory and motor pathways.
- It controls muscles and movement.
- System responses are based on skeletal muscle contraction.
Autonomic nervous system:
- The autonomic nervous system is subdivided into the sympathetic nervous system and parasympathetic nervous system
- It possesses only motor pathways.
- It controls glands and internal organs.
- This system works automatically, without a person's conscious effort.
Similarities between the somatic nervous system and the autonomic nervous system:
Both have motor pathways
Both the system use nerve impulse
Both the system Weaken Myocytes
Both the system use glucose as an energy source for the muscles that they control
Both the system are controlled by the CNS
Both possess neurons
<u>Full question:</u>
For a moment after hearing his dog's high-pitched bark, Mr. Silvers has a vivid auditory impression of the dog's yelp. His experience most clearly illustrates ________ memory.
echoic
short-term
iconic
procedural
<u>Answer:</u>
His experience most clearly illustrates echoic
memory.
<u>Explanation:</u>
Echoic memory is a portion of sensory memory and relates to auditory memories. The sensory memory that conveys into record sounds that you’ve recently confronted is a kind of this memory type. When you listen to a sound, your ears convey that sound to the brain and it is saved by echoic memory for an aggregate of four seconds.
While that concise time, your mind forms and holds an accurate reflection of the sound that you listened, so that if you stayed in a tranquil room you could yet "listen" it subsequent the sound has ended.
