Which best describes probability?

the chance that something will happen

Explanation:

Probability is the extent to which something is probable; the likelihood of something happening or being the case. It is the chance that something will happen.

We say it is the likelihood of an event happening, an event being a set of outcomes of an experiment to which a probability is assigned.The probability of a given event is a measure of the likelihood that the event occurs. Probability, itself, is the branch of mathematics which studies how such a measure can be calculated or estimated and of how the probabilities of events can be combined.

Hope This  Helped ;-;

:)

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
