Answer: Option (a) is the correct answer.

Explanation:

An enzyme is a type of protein that acts as a catalyst which helps in speeding up a biochemical reaction in living organisms.

Whereas inhibitors are the substances that inhibit the speed of a chemical reaction. That is, inhibitors help in slow down of a chemical reaction.

The basic building blocks of proteins are known as amino acids.

Thus, we can conclude that enzymes are the proteins that speed up chemical reactions.

Answer:

2.25 g

Explanation:

The mass of the solid X must be the total mass (beaker + solid X) less than the mass of the beaker. Then:

mass of the solid X = 34.40 - 32.15

mass of the solid X = 2.25 g

The difference of 0.25 g must occur for several problems: an incorrect weight in the balance, the configuration of the balance, the solid can be hydrophilic and absorbs water, and others.

What are some factors that might stop populations exponential growth?
ipn [44]
Economy - If there isn't a sustainable economy, it won't be able to support many people so instead they are limited.

Government- If people are not agreeing with the government and are against, many will leave. They won't be able to withstand it.

Overpopulation- If there is too many people, they may restrict how many babies you can have and how many people can live there. China, a co

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. If the can is warmed up on a hot plate, wh
Oksana_A [137]

Explanation:

Since atoms of solid aluminium can are closer to each other, therefore, when heat is supplied then transfer of energy in the form of heat will be faster.

As a result, when can is warmed up then atoms of solid aluminium can will start to vibrate more because heat will decrease the force of attraction between the molecules.

Thus, atoms will start to move away from each other and hence, they will vibrate more.

<span>For the answer to the question above,
Addition of HCl causes a precipitate to form: 
Ag+ & Cl- -- AgCl a white ppt 


H2SO4 is added to the supernate another precipitate forms: 
Ba+2 & SO4-2 --> BaSO4 a white ppt 


a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed: 
no Mn+2 & no Cu+2 which would have ppt as hydroxides</span>
I hope this helps you.
