Answer:
The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.plants produce food for themselves, they are known as producers.Many fungi play a critical environmental role as _______, breaking down organic material into nutrients for the soil and other organisms.
What type of evolutionary mechanism did this story show?
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

Many freshwater plants have adapted to low carbon and light levels by adapting what feature?
Group of answer choices
Carnivorous plants
No need for carbon dioxide
Camouflage
Floating leaves
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.

Which of the following statements are true regarding cellular reproduction? Select all that apply.
When an organism grows, cellular reproduction creates new cells.
Organisms reproduce, so new cells are needed.
If cells become damaged, cellular reproduction can repair damaged cells.
Cellular reproduction helps organisms acquire water better, as there are more cells present.

Answer: Replacing dead cells
Explain the difference between homology and analogy using a wolf, a whale, and a shark:
Answer:
Explanation:
Analogy refers to traits or structures like body shapes, fins which evolved independently that are similar in organisms that are not related by the same common ancestor. For example dolphins and shark have similar body structures like fins but they are unrelated. Whale and shark too. Whales are mammals, sharks are fish.
Homology refers to traits or structures
posses by organisms that are related by common ancestors. Example wolf and whales.....they are both mammals.

Some fungi and insects benefit each other; the fungi protect the insects from predators and the insects spread spores for the fungi. This is an example of a mutualistic relationship.
What is a Mutualistic relationship?A mutualistic relationship may be defined as a +,+ type of interaction in which both species benefit from the existence of each other. Example includes lichens, mycorrhizae association, coral reefs, etc.
In the question, the Fungi protect the insects from predators and benefit the insects to get survivability, while in return insects spread spores for the fungi and assist them in their reproduction process.
Therefore, both insects and fungi undergo a mutualistic type of relationship through which both species benefit from the existence of each other.

Story #1
Once upon a time, there lived a population of mountain people whose members all had wings but different
types-either bat wings or bird wings. 40% of the population had bat wings and 60% of the population had bird
wings. One day, a storm hit that lasted for several weeks. Those with bat wings were able to fly around and
find food because their wings were water resistant, while those with bird wings were not able to get food
because their feathers were not water resistant and got soaked through. Many of the bird-winged people starved
and did not survive, so their alleles decreased in the gene pool, lowering the frequency of the bird wings in
future generations. Over many generations, the environment had more and more long periods of rain and the
genetic makeup of the population shifted to 10% with bird wings and 90% with bat wings.
What is the trait being described?
What are the variations that exist in this population?
3. How did the event lead to the change in allele frequency?
Alleles?
4. What type of evolutionary mechanism did this story show?
5. Was there an adaptation in this story? If so, identify it.
6. Did the change make the population more or less similar to other populations?
7. Would this increase or decrease reproductive isolation?
Increase or decrease speciation?
8. Did the new population change for the better, worse, or have no effect? Why?
Answer:
The trait being described is the ability to fly in rainy season.
Explanation:
The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.
Answer:
Yes, it is possible.
Explanation:
In this case, I'm guessing you mean breeding.
If that's the case, they will form hybrids.
Between two different species, inter specific hybrids will be formed.
Between two different genus, intergeneric hybrids will be formed.
There's even rare cases of breeding between two families.
So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.
So to answer your question, it is possible.

Is Earth always the same distance from the
Sun? Explain.
Answer:
No
Explanation:
The earth travels in an ellipse, an ellipse is a flattened circle, and the sun is closer to one end of that ellipse and far in another end. That said the Earth is not the same distance as the sun
Does the distance from earth to sun determine the seasons? please explain
Answer:
nope
Explanation:
Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.
