Answer:
Fever c) is regulated by chemicals that reset the body's thermostat to a higher setting
Explanation:
Fever is a high body temperature and is one of the ways our immune system attempts to combat an infection. It is also referred to as pyrexia and it could be more than between 37.2 and 38.3 °C (99.0 and 100.9 °F) in humans, there is not a single agreed-upon upper limit. <em>Temperature is regulated in the hypothalamus.</em> Fever helps your immune system fight infections by speeding up the functioning of cells and it makes it harder for bacteria and viruses to thrive in the body.
The correct answer is option A, that is, Phylum Porifera.
The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.
They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.
It is called a voluntary response if it does pass through the brain ( a part of the central nervous system) but if it doesn’t pass through the brain it is called a reflex arc.
1.The pH of a particular part of the digestive system can give an approximate value about the acid content present in it. Which can help to determine the solubility of bacterias present in it. It also helps in protein denaturation process also. It helps to break down the carbon-based molecules and releases the energy for performing various activities.
2.im not sure
because they will be more healthy and will know more about the outside world
