Dual innervation refers to an organ receiving A) both sensory and motor nerves.B) both sympathetic and parasympathetic innervati
Talja [164]

Answer:

The correct option is B.

Explanation:

Dual innervation is a biochemical process by which an organ receives two different types of stimulation simultaneously. The principal function of dual innervation is to maintain the homeostatic balance of the body system. Dual innervation is brought about by two different systems, the sympathetic and the parasympathetic nerve systems. Although the actions of these two nerve systems are opposites to one another, they work together to bring balance to the body system. Without dual innervation the homeostatic system of the body can not be maintained.

Climate warming trends allow plant and insect species to inhabit larger ranges. True or false?
attashe74 [19]

The right answer is True.

At the global level, climate change will contribute to the disruption of the Earth's natural ecosystems, which could lead to the extinction of wild animal species and plants. It is mainly the impact of climate change on habitat and ecosystems that will dictate the impacts on biodiversity (by expanding them or the opposite).

Climate change will profoundly affect agricultural and forestry production. The effects in terms of production potential will be very variable depending on the regions and plant cover. They can result in an overall tendency for moderate stimulation in temperate climates and for limited warming at 2 ° -3 ° C.
