Which of your cells respond to maintain temperature and how do they do this?

1 answer:

6 0

Several cells aid in maintaining and/or regulating the body temperature. Cells in the different system of the body including Sensors in the nervous system, hypothalamus in the CNS and sweat gland in the Endocrine system. Normal body temperature usually ranges at a set point from about 36.5 to 37.5 celsius.
When the body falls below or above this set points, several cells including those aforementioned aids to stabilize the body temperature back to its set point.

When there is a deviation from the set point, the sensors in the CNS and PNS send information to the hypothalamus which regulates temperature in the brain. Blood vessels then either constrict (if cold or below body temperature) to preserve heat) and the skeletal muscles contribute by helping the body to shriver in order to raise body temperature. Contrary, blood vessels will dilate if the body temperature has risen beyond 37.5 celsius. In this case, the sweat gland helps secrete sweat to help cool down the body.

ANSWER ASAP PLEASE <br><br> What impact do trees have on the food web?

kati45 [8]

Answer:

Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.

Why is the axis important for seasons?

If the earth wasn't spinning , we wouldn't have summer, winter, fall, spring etc, it is important because we need the sun for certain seasons and no sun for others.

Why were the Smith and Cuvier discoveries that similar groups of fossils in distant rock layers could be correlated such a major

tamaranim1 [39]

This was a major breakthrough in geology because it meant that sedimentary strata in diverse parts of a country or area could be correlated as belonging to the same formation which means they were formed at the same time historically so helped to put them in the correct sequence. If these strata contained valuable minerals like coal then it could aid in the search for coal. This helped William 'Strata' Smith in England to create his first geological map in the world of a whole country.

What's the difference between nitrification and dentification

Y_Kistochka [10]

Difference between nitrification and dentrification

Explanation:

Nitrification and denitrification are part of the nitrogen cycle

Nitrification is the process of conversion of ammonium to nitrate by nitrifying bacteria like Nitrobacter and Nitrosomonas

Denitrification is the process of reduction of nitrate to nitrogen gas by denitrifying bacteria like Pseudomonos, Lactobacillus etc.

Nitrifying bacteria are autotrophs and grows slowly and need aerobic condition. Denitrifying bacteria are hetertrophs and grows rapidly and need anaerobic conditions.

Nitrification requires a pH of about 6.5 to 8.0; denitrification takes place at 7.0 to 8.5

Nitrification provides soluble nitrates readily available in the soil to be easily absorbed by the roots.

Denitrification processes are used in wastewater or effluent treatment plants.
