C. Enzyme because they catalyze biochemical reactions
dangina [55]3 years ago
3 0

Answer: Option (C) is the correct answer.

Explanation:

An enzyme is similar to a catalyst as it helps in increasing the rate of a biochemical reaction.

Also, like catalysts an enzyme does not get consumed in a reaction. They also help in lowering the activation energy and helps the reactant molecules to cross the energy barrier easily so that rate of reaction speeds up.

Thus, we can conclude that an enzyme could be the catalyst in a chemical reaction.

Which type of reaction is represented by the generic equation ab cd right arrow. ad cb? combustion decomposition single replacem
arsen [322]

The illustration would be that of a double replacement reaction.

<h3>What are double replacement reactions?</h3>

They are reactions in which 2 ionic compounds exchange ions to form two new products.

Thus, in the reaction: ab + cd ----------> ad + cb

ab and cd are two ionic compounds. The b in ab is replaced by the d in cd while the d in cd itself is replaced by the b in ab. Hence, new products, ad and cd, are formed.

Allushta [10]

Answer:

Anita did not make the track team this year, and she feels really disappointed and upset. What question would most likely redirect her thinking and provide a solution?

Why did this terrible thing happen to me?

What other sports can I try this spring?

Why does everything I attempt go wrong?

Why did Karen get on the team but I didn't?

Answer - What other sports can I try this spring?

Explanation:

Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.

when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.  

The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.

When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.

Why would the white blood cells have an abundance of lysosomes?
77julia77 [94]

Answer:

Explanation:

A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.

Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.
