2.Adaptation is when a animal has to get used to it's new environment such as getting a pet from Petco the animal needs to get used to YOU. and the environment you have given it.
3.Biodiveristy refers to all the variety of life that can be found in earth.
Ex: Plants,animals,Fungi, And micro-organisms.
This also includes the community that they form and the habits in which they live.
4Extinction is when an animal species can no longer be created or found in other cases this means the animal will be remembered in photos,videos,And drawings
Ex: If all the dogs in the world die in just the matter of seconds and they cannot breed or scientifically create one. then the animal is no longer part of the world species. thus making it extinct.

1) Students in a science class created Eco columns to mimic a small ecosystem. Grass seeds were planted in 50 grams of potting soil, insect species were added, and 100 ml of water was administered.
Which statement(s) are supported by the data in the table? Select ALL That apply.
A) The grass height was the dependent variable.
B) The grass height was the independent variable.
C) The presence of insects was the independent variable.
D) The presence of the water was the independent variable.
E) Intermediate numbers of insects had the greatest positive impact on grass growth.
B) The grass height was the dependent variable.
E) Intermediate numbers of insects had the greatest positive impact on grass growth.
How insects affect the plant growth?The grass height was the dependent variable because it depends on the nitrogenous waste of insects and presence of water. The numbers of insects had the greatest positive impact on grass growth because they provides nutrients to plant in the form of nitrogenous water so we can conclude that option B and E are the correct options.

Dichotomous key.
HELP PLS !!!!!
Answer:
A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification
In phylogenetics, a single-access key is an identification key where the sequence and structure of identification steps is fixed by the author of the key. At each point in the decision process, multiple alternatives are offered, each leading to a result or a further choice.

Please help. Explain whether you think nuclear energy is a viable source for the future energy needs of the
United States.
Answer:
Of course nuclear energy is a viable source for the future energy needs of the US.
Explanation:
Right now, we are using fossil fuels to fuel our daily electricity needs. But we will soon run out of steam, coal and much more fossil fuels as the years come. So we will need to make the change before it's too late, and switch to renewable energy sources or nuclear energy. Fossil fuels also cause a lot of pollution, which causes global warming, which is bad because it releases greenhouse gasses which reflect sunlight back onto the Earth, thus reducing much of the species of animals that depend on snow and ice. Glaciers will melt, which will increase the water level and soon Earth will be flooded and full of pollution, so we have to switch to better energy sources faster.
What sequence represents alternating glacial/interglacial periods during the Pennsylvanian?

Consumers rely on other
organisms. Why?
A. They cannot make their own food.
B. They cannot capture other organisms.
C. They cannot protect themselves
Consumers rely on other organisms because A. They cannot make their own food.
What are Consumer heterotrophic organisms in the ecosystems?Consumer heterotrophic organisms in the ecosystems are species that cannot synthesize their own food such as occurs in the case of animals that need to eat other organisms to satisfy their energy needs, while plants and algae are autotrophs.
Therefore, with this data, we can see that Consumer heterotrophic organisms in the ecosystems are not able to produce their own foods and therefore they need to eat other organisms to survive.

Consumers rely on other organisms because they cannot make their own food.
The correct option is A.
What are consumers in living things?In ecology, consumers are organisms that obtain their energy and nutrients by feeding on other living organisms or their organic wastes. They are also known as heterotrophs, as they cannot produce their own food and rely on other organisms for sustenance.
Consumers can be further classified based on what they eat. Herbivores are consumers that eat only plants, while carnivores eat only other animals. Omnivores eat both plants and animals, while detritivores and decomposers break down dead organic matter and recycle nutrients back into the ecosystem.

Imagine a parallel Earth that is the same as ours, but the technological life form is not human beings. The organism that evolved to create technology, culture, and civilization is a creature that is photosynthetic but is mobile like animals. Think about our different body systems, and the way our history has evolved from paleolithic to modern times. What might their physical, technological, houses, cities, and cultural development be like?
The main point of divergence between these beings would be the fact that they are photosynthetic being autotrophic beings.
What would be the advantages of moving and thinking autotrophic beings?These beings from another planet would be able to synthesize their own food from inorganic material, thus being more evolved, as they would not need to develop methods of obtaining food, leaving more resources for technological and social development.
With this information, we can conclude that the main point of divergence between these beings would be the fact that they are photosynthetic being autotrophic beings.
