A human body, just like a dog's, will sweat. Dogs will pants and sweat through the pads of their feet to cool down, and human will sweat through their foreheads, armpits, etc.
Dogs will tend to, in hot environments, lay on the floor or where the surface is cooler. Since they cannot simply strip their clothing to keep cool they tend to find cool surfaces, fans, sources of air, etc. to keep cool from the heat.
Answer:
The answer is 18.12KJ is required to vaporise 48.7 g of dichloromethane at its boiling point
Explanation:
To solve the above question we have the given variable as follows
ΔHvap = heat of vaporisation of dichloromethane per mole = 31.6KJ/mole
However since the heat of vaporisation is the heat to vaporise one mole of dichloromethane, then, for 48.7 grams of dichloromethane, we have.
The number of moles of dichloromethane present = 48.7/84.93 = 0.573 moles
Therefore, the amount of heat required to vaporise 48.7 grams of dichloromethane at its boiling point is 31.6KJ/mole×0.573moles =18.12KJ
The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Answer:
activating digestive enzymes, and making ingested proteins unravel so that digestive enzymes break down the long chains of amino acids
Answer:
The correct option is: non-covalent interactions
Explanation:
Enzymes are the macromolecules that are responsible for catalyzing biochemical reactions in the cell and thus they are known as the<u> biological catalysts.</u> They have<u> high specificity and selectivity.</u>
In an enzyme-catalyzed reaction, the substrate molecules bind to the active sites present on the surface of the enzyme, resulting in the formation of a enzyme-substrate complex, which is stabilized by weak non-covalent interactions such as Van der Waals forces, hydrophobic interactions, electrostatic forces and hydrogen bonding.
