Lactase is essential for digesting lactose in milk. This enzyme is specific for this sugar. Why?Molecules and active sites vary

in size; only properly sized molecules can fit.There is a precise compatibility between the active site and the lactose molecule.Specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed.Reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.

There is a precise compatibility between the active site and the lactose molecule.

Explanation:

An enzyme's active site has a specific shape, where only the substrate it is designed for can fit. It's much like a puzzle, where you must have the right pieces join together or else you wont get a coherent picture.

What is the phenotype of a plant with the genotype RR
vazorg [7]
To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:

R= tall stalk
r= short stalk

The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.

Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.

Mashutka [201]

Answer:

Leaves

Explanation:

Plants grow broad leaves to absorb sunlight. This is extremely helpful because this helps plants make food through photosynthesis. Roots don't absorb sunlight. They absorb water and nutrients from the soil and carry it up through the stems. The stems then transports the nutrients throughout the plant.
