<u>Answer:</u>
The<u> autonomic nervous system </u>is the part of the peripheral nervous system that directs the activity of glands, organs, and smooth muscles.
<u>Explanation:</u>
The autonomic nervous system (ANS) is a control mechanism that operates primarily unconsciously and controls body workings like respiratory rate, heart rate, pupil response, digestion, urination and sexual excitement. This method is the primary driving force for regulating the reply to fight or flight.
To regulate physiological functions, it controls involuntary responses. There are also two divisions to the ANS while these two splits have oppositional effects on their internal organs:
- the sympathetic division and
- the parasympathetic division.
Answer:
"Growers using organic soils will never concern themselves with supplying oxygen to their plants; however, hydroponic growers like me must be well versed in the science of dissolved oxygen (from here on out called DO).

Answer:
The chance that their <u>child will not be able to roll his tongue will be zero</u>.
The chances to have a child with tongue rolling ability is 100%.
Explanation:
In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.
If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.
When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.
This is:
Parental) TT x TT
Gametes) T T T T
Punnet Square) T T
T TT TT
T TT TT
F1) Genotype: 100% TT, or 4/4 TT
Phenotype: 100% Tongue rolling capable.
