Barriers are the circumstances or any other things that hinder the growth and the development of the social and mental state. Intrinsic barriers and learning are types. The problem is the extrinsic barrier.
What are the barriers and their types?An intrinsic barrier is the physical, mental, motivation, and attention-based difficulties. The extrinsic barrier is the outer factor that impedes the learning of the individual and can be due to poverty, economical state, death etc.
Learning difficulty is the problem with educational learning and the methods. This can be due to the low mental quotient, unable to understand and comprehend the study topics.
Therefore, it is an extrinsic barrier.

Answer: Metamorphic rock literally means 'changing shape', like the metamorphosis of a butterfly. These rocks undergo intense physical and chemical changes deep within the Earth. As layers of sedimentary and igneous rock are pushed into the Earth, increases in pressure and temperature start the metamorphosis.
The hypothetical rabbit population reproduces and grows. Eventually, the death rate increases due to
Limiting factors. How would you adapt this hypothetical situation to create a different result and have a
stable rabbit population without starvation and overcrowding?
A) Include another source of food for the rabbit population so there will be enough food
for all the rabbits.
B) Decrease the amount of available food for the rabbit population. The numbers will be
lower as well as the reproduction rate.
C) Add a predator to the model. That will decrease the number of rabbits surviving to
reproduce and there will be space and food to keep the rabbit population stable.
D) Introduce a disease to the rabbit population that will drastically reduce the number of
rabbits in the population. That will provide more food to the remaining rabbits.
Answer:
C
Explanation:
if you add a predator than the population will go down and there will be enough food c or d

1. What caused the tree bark to become darker?
What caused the tree bark to be darker is the day the darker the day is the darker the tree bark gets.
2. In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?
The light peppered moth had a higher rate of survival on the light bark.
3. In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
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.

Identify various types of evolutionary adaptations and describe how genetic variation and environmental factors play a role in promoting diversity and evolution through natural selection. Additionally, simulate the consequences of genetic variation and natural selection in specific environmental conditions.Hypothesis:

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. It is the result of evolution.What kind of geological forces or events cause mountains to form

After the K-Pg mass extinction event, mammals were able to survive and proliferate. Which of the following factors
contributed to this success the least? (1 point)
O most mammals being nocturnal, allowing them to see better in the darkened conditions
O ability to regulate their body temperature in the face of reduced sunlight and colder temperatures.
O more oceanic and lake habitat, leading to marine mammal evolution.
O fewer predators in the absence of dinosaurs.
Mammals survived the K-Pg mass extinction event because they are able to regulate their body temperature in the face of reduced sunlight and colder temperatures.
What is the K-Pg mass extinction event?The K-Pg mass extinction event is a sudden extinction of mammals that happened over 66 million years ago on earth and affected several species.
