Homeostasis is maintained by the respiratory system in two ways: gas exchange and regulation of blood pH. Gas exchange is performed by the lungs by eliminating carbon dioxide, a waste product given off by cellular respiration.
Answer:
Sympathetic Nervous System.
Explanation:
Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.
As a whole the autonomic nervous system controls the unconscious responses of our body.
The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.
Answer:
The outermost shell of a terrestrial planet is referred to as "crust." The Earth's crust is separated into two types: continental crust, which is older and thicker, and oceanic crust, which is younger and denser. Plate tectonics influences the dynamic geology of the Earth's crust. The outermost shell of a terrestrial planet is referred to as "crust."
The mantle is the layer immediately beneath the sima. With a thickness of 1800 miles, it is the Earth's thickest layer. The mantle is made up of extremely hot and thick rock. Under the weight of a huge load, this layer of granite even flows like asphalt. The flow is caused by large temperature differences between the mantle's bottom and top. The movement of the Earth's plates is due to the movement of the mantle! The mantle's temperature ranges from 1600 degrees Fahrenheit near the top to about 4000 degrees Fahrenheit near the bottom!
Answer:
Explanation:
A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host’s genome by an integrase enzyme. The virus thereafter replicates as part of the host cell’s DNA. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. A special variant of retroviruses are endogenous retroviruses, which are integrated into the genome of the host and inherited across generations. Endogenous retroviruses are a type of transposon.
