Which statement describes all enzymes?
a. they control the transport of materials
b. they provide energy for chemical reactions
c. they affect the rate of chemical reactions
d. they absorb oxygen from the environment
explain why.

Option C.

Explanation:

Enzymes are defined as the macromolecular that act as biological catalysts which helps to accelerate chemical reactions.

Enzymes increases the rate of chemical reaction by lowering its activation energy. Enzyme can exceed the rate of reaction million times faster..

The molecules at which enzymes act are called substrates, and substrate is converted into several other molecules are called products.

Several metabolic pathways depend upon enzymes that catalyzes every single step of reaction. Enzyme activity majorly affected by other molecules named inhibitors and activators. Inhibitors inhibits or restricts the activity of enzyme while activators increases the activity of enzymes.

Hence, enzymes affect the rate of chemical reactions.

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
