If you are startled by the sound of a loud explosion, the sympathetic nervous system will become dominant. The sympathetic nervous system is responsible for regulating not only the functioning of the visceral organs (kidneys, digestive system and circulatory system) but also all the automatic functions of the organism, such as breathing, circulation, digestion and elimination.
Answer:
5 bases
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases 
is 16 and it is not enough combination for all 17 amino acids
for 5 bases 
is 25 combinations (meaning that more than one codon could code for the same amino acid).
Answer:
1.) Stimulus ----> A change in the system or environment.
2.) Response ----> A result or event that occurs because of a change in the system.
3.) Positive Feedback ----> The goal is to amplify the response until the stimulus is removed.
4.) Negative Feedback ----> The goal is to reduce the stimulus and return to homeostasis.
<span>Endospore is a protective structure that can
able to survive for long periods of time in soil and water in which they commonly
found. They are tough, dormant and non-reproductive structure which can
withstand heat, dryness, and toxic chemicals that would kill most other
bacteria produced by a small number of bacteria like the bacterium Bacillus
thuringiensis from the Firmicute family. To ensure the survival of a bacterium
through periods of environmental stress is the primary function of most
endospores. They are also resilient to gamma and ultraviolet radiation, chemical
disinfectants, desiccation, starvation, lysozyme and temperature and can survive any environmental assaults.</span>
