The right option is; Thermoreceptors
Thermoreceptors helps her adjust to the change in the temperature of her surroundings.
Thermoreceptors are specialized nerve cells that are sensitive to detect changes in heat energy (temperature). Thermoreceptors are found in every part of the skin. They detect heat and cold, therefore, they allow sensory reception within the body. The sensitivity of the skin to temperature changes is based on the number of thermoreceptors and where they are located.
Explanation:
the DCT is the shortest segment of the nephron, spanning only about 5 mm in length in humans (1), it plays a critical role in a variety of homeostatic processes, including sodium chloride reabsorption, potassium secretion, and calcium and magnesium handling.the DCT is the shortest segment of the nephron, spanning only about 5 mm in length in humans (1), it plays a critical role in a variety of homeostatic processes, including sodium chloride reabsorption, potassium secretion, and calcium and magnesium handling.
1. The reason why the dark-colored variety was in greater numbers present in the polluted environment is that the dark-colored moths were better adapted to the environment.
The pollution killed the lichens which caused the tree trunks to have a much darker color than before. The dark color of the tree trunks permitted the dark-colored moths to hide and camouflage from the predators. That is why the dark-colored moths were better adapted to the polluted environment.
2. There could be many reasons why the light-colored variety was not completely eliminated from the polluted environment. The light-colored variety could be less effectively adapted to the polluted environment, but it wasn't completely extinct.
This is because the light-colored moths could be resting and hiding in other places and not on the tree trunk. Also, some of the light-colored moths found in the polluted environment could have migrated from other less polluted places. Finally, some of the dark-colored moths could be carrying the allele for the light color.
3. The air pollution control laws could help reverse the environmental destruction caused by the industrialization. This could help in significantly decreasing the air pollution and restoring the balance of the ecosystem. If the pollution decreases, the population of lichens could recover and the tree trunks could be covered again with lichens. This, in turn, would make the color of the tree trunks lighter and the light-colored moths could hide and camouflage on the tree trunks again.
4. The diagram shows the percentage of each moth variety in the two different environments, the polluted and the non-polluted environment.
The percentage of dark-colored moths in the non-polluted environment was closest to 15% and in the polluted environment, it nearly rose to 70%.
The percentage of the light-colored moths in the non-polluted environment was nearly 85% and in the polluted environment it was closest to 24%.
5. The correct answer is "a given trait can be a favorable adaptation in one environment, but not in another environment".
An evolutionary adaptation is a term referring to the characteristics of an organism which help him survive in a specific environment. If the environmental conditions change, the characteristics which were once favorable may no longer be.
This is what all the above information shows; any change in the environment can make a once favorable adaptation disadvantageous.
A proposed explanation for a natural phenomenon is a hypothesis.
The hypothesis can also be known as an educated opinion.
