I NEED BIOLOGY HELP! Background: All living cells contain enzymes. One of these enzymes, called catalase, breaks down a substance

called hydrogen peroxide (H2O2) that can build up in your cells. The enzymes change hydrogen peroxide into

oxygen gas (O2) and water (H2O). The chemical equation that represents this chemical reaction is:

Enzyme (catalase) action

2 H2O2 → O2 (gas) + 2H2O

Please help me answer the questions below:

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

the correct answer is sex-linked recessive.
