Answer: Hi there, I'm so sorry no one answer your question here is what I got
The nervous system makes you thirsty. The integumentary system makes you sweat.
The hypothalamus is part of the nervous system and controls vegetative functions, such as hunger, thirst and body temperature. When you run a race, your body starts to lose fluids due to sweat. At that moment the nervous system (through the hypothalamus) trying to maintain homeostasis in your body signals that you are thirsty.
As already mentioned above, when you participate in a race you start to sweat. This is a reaction of the integumentary system, through the skin, releasing fluids to regulate your body temperature.
Explanation:
Photosynthesis starts when a photon- a tiny packet of light is absorbing a molecule of chlorophyll.
Answer:
(B) They may have binding sites for regulatory molecules that are separate from active sites.
(C) They generally have more than one subunit.
(E) They interconvert between a more active form and a less active form.
Explanation:
Allosteric enzymes are the regulatory enzymes that have a specific site for binding of modulator or effector molecule. The activity of these enzymes is altered by the noncovalent binding of modulators at the allosteric site. The binding of the modulator brings about a conformational change in the allosteric enzymes.
The relatively inactive conformation of these enzymes is called T state while the active conformation is the R state. Most of the allosteric enzymes have multiple subunits and deviate from Michaelis–Menten kinetics and exhibit a sigmoid saturation curve of V0 vs. [S].
Diffusion is the spontaneous movement of substances from a region of high concentration to a region of low concentration.
Osmosis is the passage of water molecules from a high water concentration region through a selectively permeable membrane to a low water concentration region.
In diffusion, selectively permeable membrane is neither required nor involved while in osmosis, it is involved.
This is called Biomagnification - concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
