Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Pie

Answer:

Due to increasing the survival.

Explanation:

The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.

Which laundry detergent removes stains more effectively?
TEA [102]

Enzyme-containing laundry detergents will remove stains more effectively than detergents without enzymes. Stains will be removed more successfully from clothing with homemade laundry detergent than from commercial detergents.

A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable. A person's age won't alter as a result of other circumstances like what they eat, how much they attend school, or how much television they watch. In actuality, when attempting to establish a link between two variables, you are attempting to determine whether the independent variable affects the dependent variables in any way.

A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend. A test score, for instance, maybe a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.
