An enzyme is a catalyst which means it changes the speed at which a chemical reaction occurs. It never alters the reaction in any way or changes nay chemical properties, only the speed at which it occurs and is completely absorbed in the meantime. The substrates that are reacting just have their reaction faster.
Answer:
A limiting factor is anything in an environment/ecosystem that limits a population's size. They can be anything from the amount of available food, shelter, and competition.
I’m pretty sure it’s D, the others don’t make sense??
Answer:A
Explanation:
The mass of an electron is equal to the mass of a neutron
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
Answer:
The correct answer:
1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)
2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)
Explanation:
As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).
Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:
1. 100 × 35/100 ⇒ 35% of 100
2. 200 × 25/100 ⇒ 25% of 200
