The dark peppered moth had a higher rate o survival then the light peppered moth on a dark bark.
4. During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
The trees were also darkened as a result and the light-bodies moths that were able to blend with the light-coloured lichens and tree barks were in danger due to their predation by the birds. This shows to the rapid decrease of the light-coloured moths.
5. Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
I think the dark peppered moth had more chance to survive in my neighbourhood because its a lot of times dark and faster here because we are more in the north.

Data Analysis:
Make a graph with the data above I can't put it in.Conclusion:
My hypotheses were supported since I reckoned that if the white rabbit is in the light environment its population will increase while if it were in a dark environment their population will decrease. According to the data table, in the start the population of white rabbits in the light environment was 55% and nearing the end it sky rocketed to 97%. While, in the dark environment it started with being 40% and at the end of the study it falled down to 6%. All in all, the brown rabbits camouflage best in dark environments while white rabbits camouflage best in light envirmnets and this is because of the color of each environment and each rabbit. Everything considered, the population of brown rabbits will continue to decrease while the population of white rabbits will continue to increase in a light environment. While, the population of white rabbits will continue to decrease and the population of brown rabbits will steadily increase in a dark enviornment.Questions:
How did the colors of each type of prey affect its population size over time? Address each color of rabbit in your answer.
The more an animal's color matches its environment, the better its chances of survival. White rabbit fur looks like snow, brown rabbit fur looks like dirt. So if a white rabbit is in the woods predators will spot it very easily and the same goes with a brown rabbit if it is in snow.How do you predict the data would change in each environment if you continued? Address each color of rabbit in your answer.
If I were to continue my data in each environment I predict that it would change by minimizing the percentage of brown rabbits in a light colored environment and the percentage of white rabbits in a dark colored envirnment.What traits would help a predator to be more "fit" to survive in each environment? Be specific.
If a predator can camouflage its surroundings, make less noise, have good hearing, and can move quickly, it is likely to be more suitable. Appearance can affect a person's survival. Not just the color, but also the sharp teeth, rough skin, and beak and claws to fight predators. High power and acceleration are also great, but for some species, slower can be useful counting on the environment when hunting. I have.Describe other adaptations, besides color, that could affect the prey’s survival.
Camouflage is an adaptation that helps an organism blend in with its environment. Shuffling helps animals avoid predators and increase survival. Mimicry is a developed similarity between an organism and an object that protects it from predators. Moths, for example, grow brown like the bark of trees and blend in, reducing their chances of being eaten. This benefits the animal as it is less likely to be attacked by predators.Explain what will happen if there are not enough resources to support the individuals in a species.
I assume that when resources are scarce, there will be deaths and the overall population will decline. Birth rates are declining because there are not even enough resources to raise babies. There will also be battles for resources that allow the fittest to survive.This experiment tested natural selection. Explain another possible mechanism of evolution for the rabbits to evolve. Be specific.
White rabbits survive in the snow and die in forest environments, and brown rabbits do the opposite, as color traits are adaptive traits.

b.the set of behaviors that are not learned
c.the group of hormones that cause plants to grow and develop
d.the ability of an organism to maintain a consistent internal environment
Answers
Answer:
A
Explanation:
Living organisms adapt to their moves and positions in response to the environmental changes for their protection or to their advantage. When an entity reacts to the changes in its surroundings, it is referred to as stimulus while the reaction to the stimulus is referred to as a response. Common stimuli are sound, light, air, heat, smell, taste, water and gravity.
Think of burning your finger of fracturing your bone without any pain sensation. It may certainly sound like a superpower or an ideal situation, however, when it comes to the standpoint of survival, it can be disastrous.
It is a characteristic behaviour of living entities to respond to stimuli with the intervention of the Nervous System. It is an organ system ascribed to send signals from the spinal cord and the brain throughout the body and then back from all the body parts to the brain. Neuron acts as the mediator and is the basic signalling unit of the Nervous system.
Pain is the body’s way of letting us know that something is not right. It can prevent further injuries or push us to seek medical attention. Moreover, all of this is possible because humans can respond and react to stimuli due to control and coordination among the various organs and organ systems.
Control and Coordination in simple multicellular organisms take place through only the Nervous system which coordinates activities of our body. It is the control system for all our actions, thinking, and behaviour.
