Answer:
a. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

b. Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains. Amylases break down starches, and lipases break down fats and grease.
Explanation:
I'd say B or D..technically higher salt levels are caused by evaporation. so probably B
<u>Answer:</u>
<u>D. Type of bee carrying the pollen</u>
Explanation:
Remember, Lilies are aquatic plants, so in order to rule out Environmental Variation, that is, differences in environment, we are to make constant all the environmental factors which include the options;
- Temperature
- Amount of sunlight
- Amount of water
However, the none environmental factor which is the type of bee carrying the pollen is exempted.
If a person had a dominant allele for blonde hair and a recessive allele for red hair, the probability of that person having red hair would be closest to 100 percent. The dominant allele will express while the recessive allele would require two copies of genes to give the red color. The lone expression of the allele for blonde hair would lead to the presence of blonde hair on the head.
