Answer:
the production of carbon dioxides when soil organisms breathe.
Explanation:
soil or cellular respiration is a key ecosystem process that releases carbon from the soil in the form of CO 2.
Answer:
= 
Explanation:
Given that the woman’s maternal grandfather is color-blind, then it is possible that the woman is a carrier of color-blind allele.
Then probability that the woman is a carrier of color-blind allele is = 
So if a carrier woman cross with a normal man
Let say the gene of the carrier woman is: 
and the normal man = 
so if we have a cross between and ; we have:
we can see the offspring to be :
=normal unaffected female
= normal unaffected male
= carrier female for color-blind
= carrier male for color-bind
Then probability that of inheriting defective allele = 
=
Let's not forget that the probability that the woman is a carrier of color-blind allele is =
∴ the probability that the son is colorblind = 
=
Answer:
most innervation from the vagus nerve
Explanation:
Peripheral nervous system consists of all the neurons and ganglia within the body, outside the central nervous system. It is divided into:
- Somatic nervous system- it controls the movements of skeletal muscles which means that this nervous system is under the voluntary control
- Autonomic nervous system- its role is to control involuntary movements of smooth muscles and glands
Autonomic nervous system consists of:
- sympathetic nervous system
-responsible for the "fight and flight" reactions (stressful situations but also for maintaining homeostasis)
- parasympathetic nervous system
-opposite to sympathetic system, responsible for "rest and digest" reactions (body activities at rest)
- enteric nervous system-controls digestion
