High temperatures denature proteins by disrupting their hydrogen
bonds. how might this affect the ability of an enzyme to catalyze
reactions?

Enzymes can be described as proteins which are used to speed up a reaction.

A certain increase in temperature increases the catalytic activity for an enzyme.

But beyond a certain temperature, an enzyme will become denatured and it will no longer be able to catalyze the reaction. The active site of the enzyme will get changed and it will no longer allow a particular substrate to fit into it.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
