Answer:

12:4:3

Explanation:

Let the lack of color pigmentation which is recessive be aa where AA and Aa allow for color (BB, Bb - black, baby - white).

The F1 parents are BbAa x BbAa

This cross will produce 12/16 blacks, 4/16 albinos and 3/16 white.

<h3>What is an enzyme?</h3>

Enzymes are proteins that help speed up metabolism or the chemical reactions in our bodies.

They build some substances and break others down.

All living things have enzymes. Our bodies naturally produce enzymes.

But enzymes are also in manufactured products and food.

Examples of specific enzymes:

Amylase: In the saliva, amylase helps change starches into sugars.

Maltase: This also occurs in the saliva, and breaks the sugar maltose into glucose.

Trypsin: These enzymes break proteins down into amino acids in the small intestine.

HELP! This is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
skad [1K]

Available oxygen

Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.

Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.

<h3>Evolution and natural selection </h3>

The term evolution refers to the biological process of descendence with modification.

Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.

In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.
