All organisms have adaptations. The list below describes how different adaptations might affect different species.A bird species that develops a longer beak would be able to extract insects from holes that are deep within trees.

A plant species that develops the ability to excrete salt through the leaves of the plant could survive in soils that have high concentrations of salt.

A rodent species that develops the ability to hibernate, or remain inactive during the winter months, would be able to conserve energy when little food is available.
Which of the following is true?

Answers

Hello. You forgot to enter the answer options. The options are:

"A)Adaptations increase the probability of an organism surviving and reproducing in a specific environment. B)Sudden environmental changes are always necessary for the development of new adaptations. C)The inherited characteristics of a species change over time based on the use or disuse of particular characteristics. D)Adaptations allow individual organisms to change their structures based on environmental conditions."

Answer:

A)Adaptations increase the probability of an organism surviving and reproducing in a specific environment.

Explanation:

The adaptations of living beings do not occur by chance, much less occurred overnight. Throughout the evolutionary process, some organisms have undergone transformations that have given them greater chances of survival in the environment, adjusting morphologically and physiologically to the ecosystem in which they live.

To these transformations, selected by the environment and caused by mutations, we call adaptation, related to the defense mechanism, reproduction, locomotion, food and unfavorable weather conditions.

What is a series circuit? (Definition)

Answers

A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors:
