In a pressure cooker, a lid is screwed tightly onto a pot so that the air pressure in the pot is increased. What effect, if any, will this have on the boiling point of water in the pot?The boiling point will be raised. The boiling point will be lowered. The boiling point will be unaffected. None of the above.
Answers
A liquid boils when it's vapor pressure will be equal to the atmospheric pressure. With the lid on, increases the pressure inside the pot. As an effect, it would take a higher temperature to reach the boiling temperature.
Answer: The boiling point will be raised.
If a lid is screwed on tightly in a pressure cooker, the air pressure is increased. This will make the boiling point of the water to be raised.

How many cases of measles would you predict were reported last year
Answers
In the laws of mathematics, especially in rounding off digits, you should take note of the digit following that number no matter how long or short a number is. If the numberis preceded by numbers between 0-4, the number does not change. However if its is preceded by numbers between 5-9, add one to the number. For example, 145698. If it is rounded off to the nearest hundreds, since 9 is the number after 6, add 1 to 6 and it becomes 145700. If it is rounded off to the nearest hundred thousands, since 4 is the number after 1, you do not add, the number stays the same and it becomes 100000

Which two substances bind using a lock-and-key mechanism?enzyme and substrate reactant and substrate substrate and product reactant and product
Answers
The answer is the first option. Enzyme and substrate bind using a lock-and-key mechanism. Enzymes act on a specific substrate and a substrate needs a specific enzyme, this is what is called a lock-and-key mechanism. Enzymes and substtates are like a key and a lock, one is for each other.
