Which of the following is most likely to happen to a liquid substance when the temperature is increased?
Marta_Voda [28]

Answer

:When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... When the pressure exerted on a substance increases, it can cause the substance to condense.

3. The human body has devised an excellent method to keep the body pH under control. a. What principle underlies the constant pH
kumpel [21]

The normal blood pH for adult humans is 7.40, and this pH value is vigorously defended at normal body temperature

Acid base Homeostasis is the method by which body keeps a constant ph
pH is kept under check via different systems
1. Chemical system :bicarbonate buffer system(explained below )
Respiratory component :
2. Respiratory Component: The second line of dense is rapid consisting of the control the carbonic acid concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation. This blows off or retains carbon dioxide (and thus carbonic acid) in the blood plasma as required

3.Metabolic component : third line of defense is slow, best measured by the base excess,eand mostly depends on the renal system which can add or remove bicarbonate ions to or from the ECF.Bicarbonate ions are derived from metabolic carbon dioxide which is enzymatically converted to carbonic acid in the renal tubular cells.There, carbonic acid spontaneously dissociates into hydrogen ions and bicarbonate ions.When the pH in the ECF falls, hydrogen ions are excreted into urine, while bicarbonate ions are secreted into blood plasma, causing the plasma pH to rise.The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma.




Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system’s pH within a narrow range.

Maintaining a constant blood pH is critical to a person’s well-being. The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. Similarly, excess carbonic acid can be converted into carbon dioxide gas and exhaled through the lungs; this prevents too many free hydrogen ions from building up in the blood and dangerously reducing its pH; likewise, if too much OH– is introduced into the system, carbonic acid will combine with it to create bicarbonate, lowering the pH.
Example: Antacids, which combat excess stomach acid, are another example of buffers.

Which of the following statements about prey choice is not correct?
gogolik [260]

Answer: d. Predators avoid prey that are in their prime in order to maintain a high reproductive rate in the prey population, and hence 'grow' prey for the future.

Explanation:

A predator can be define as an organism superior and strong enough to kill inferior and weaker organism. This organism kill other organism to obtain it as food. A prey is an organism which is weak and cannot defend itself from the attack of the superior organism.

d. is the correct option. This is because the predators do not bother about the age and strength of the prey. They attack over them whether the prey is weak , young, prime, or old and try to obtain it as food.

PLEASE HELP ASAP 5 MINUTES LEFT<br><br> what is the role of the enzyme diaphorase
Stells [14]

Diaphorase or dihydrolipoyl dehydrogenase is a flavoprotein enzyme capable of oxidizing the reduced form of NAD (NADH). This lipoamide dehydrogenase is a component of the glycine cleavage system, as well as of the alpha-ketoacid dehydrogenase complexes. It binds one FAD per protein subunit. The enzyme is provided in 3.2 M ammonium sulphate.
