Natural selection is the process of small genetic variation in organisms leading to the gradual development of a species.
What is natural selection?"It is the process whereby organisms better adapted to their environment tend to survive and produce more offspring."It depends on the environment and genetic variation.Genetic variation is the changes in the genome.This will result in offspring with different characteristics that their parent species.As time passes this will lead to the development of new species.Hence, the correct answer is: variation.

Answer:
There are three stages of the dragonfly life cycle, the egg, the nymph, and the adult dragonfly. Most of the life cycle of a dragonfly is lived out in the nymph stage
Life as an Aquatic Larva
Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. After the egg hatches, the free-crawling aquatic larva molts once and then starts hunting voraciously. As the larva grows, it will molt numerous times. Most dragonfly larvae mature to adulthood in one to three years. so maybe *(c.)

In a few words, describe the differences in a recessive phenotype and a dominant genotype.
Answer:
Recessive phenotype is that type of phenotype that is expressed by an organism only when both the alleles of a genotype are recessive. Dominant genotype is that type genotype were either one of the alleles or both the alleles are dominant.
Explanation:
Phenotype is the physical appearance of an organism whereas genotype is the genetic makeup of an organism. A recessive phenotype is expressed only when both the alleles are recessive for the trait.
What is genotype and phenotype?
The genotype of an individual is their unique sequence of DNA or genome. More specifically, the term genotype is used to refer to the two alleles a person has inherited for a particular gene from their parents. Phenotype is the physical appearance or expression of the genotype.
Recessive phenotype is the type of phenotype which is expressed by an organism only when both the alleles of a gene are recessive in that organism. And, dominant genotype is the type of genotype which is observed when either one of the alleles or both the alleles are dominant for that trait.

How did the environment change? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. You cannot tell how the environment changed. With each generation, more guppies passed on the gene for small spots to their offspring.
2. The rocks became smaller. With each generation, more guppies with small spots survived long enough to pass on the gene for small spots to their offspring.
3. The rocks became smaller. Guppies with small spots are more likely to survive, so the guppies with large spots changed to have small spots.
4.The rocks became smaller. Guppies with small spots are more likely to survive, so both kinds of guppies passed on the gene for small spots to their offspring.
Answer:
1.you cannot tell how the environment changed. with each generation, more guppies passed on the gene for small spots to their offspring.
Explanation:
the diagram doesn't show/say anything about the environment changing. it just shows that at time 1 there were an equal amount of guppies with small and large spots and then the second one had more guppies with small spots, meaning that they must've reproduced more and began to outweigh the guppies with large spots.

Do large muscles occur naturally in some other living things? (List the living things and explain why you think these larger muscles occur naturally.)
Answer:
Yes, large muscles occur in some other living things. I think this because lets say you have a cheetah. Well, that cheetah runs very fast AND uses muscular endurances to hunt and chase its prey down. So yes, they start to devolp some large muscles. Some other living things that might have large muscles could be a bear, rhino, lion, tiger, or even a dog. As you can see, its more so the larger animals that devolp these large muscles.

The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answer:
Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase. More gar means more predators for the crabs, and therefore decrease the crab population. More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.
Explanation:
To fully understand this question it is important to realize the relationship in this food web. It is important to note that the alligators will eat gar, the gar will eat crab, and the diving duck also eat carb. If the predator population decreases, then the amount of prey will be able to increase since there are less predators hunting them. If the predator population were to increase, there would be less prey, since more predators are hunting them.
The data showed the decrease in the population of alligator. The decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.
What is the relationship between different animals?All animals and plants are dependent on each other. In the given picture, the crabs, crocodiles, gar, and diving duck is given.
If there will be fewer crocodiles, the population of gar will increase that affects the population of crabs, because duck and gar both will eat the crabs.
Thus, the decrease in the population of alligator will increase the population of gar and, which will decrease the population of crabs, and it increases the competition between gar and diving duck.

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported
Answer:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.

Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. No blue jays could have been born with a thin-beak trait because none of the adult blue jays had that trait to pass down.
2. No blue jays could have been born with a thin-beak trait in the past, but some with that trait could be born in the future if the environment changes to have pine cones with seeds.
3. A blue jay could have been born with a mutation in its genes for the thin-beak trait and lived for a little while, but it would have been more likely to die before it had offspring.
4. A blue jay could have been born with a mutation in its genes for the thin-beak trait, but having a mutation in its genes would have caused it to die when it was born.
Answer:
i believe the answer is 2)
Explanation:
because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**

What is environment?An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.
Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.
Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.
Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.
The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.
Thus, this can be the complete scenario for the gold fish.

As fall arrived, Steven saw that many homes had chrysanthemums planted in their flowerbeds. Their golden colors always signal the oncoming fall season.
Many plants respond to seasonal changes.
Why might a plant such as a chrysanthemum bloom during the fall?
a. the plant may be conditioned to live in a particular climate
b. the plant may be better suited to survive in cooler weather
c. the plant may be unable to adapt to cold weather
d. the plant may not respond to seasonal changes
Answer:
A
Explanation:
Plants such as chrysanthemum bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.
What are the effects of seasonal changes on plants?The effects of seasonal changes on plants might be determined by the fact that plants also adapt to the seasons if they live in a place that has strong seasons. Plants will shed their leaves during the winter if there isn't enough light, or shed their leaves during the dry season if there isn't enough water.
This response of flowerbeds through chrysanthemums represents the significance of seasonal change through which plants increases their survival. This is due to the conditional behavior shown by plants in order to facilitate their survival in the natural ecosystem.
Therefore, plants such as chrysanthemums bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.

Explanation:
Roots of prairie plants are developed through centuries of growth. These deep roots will take the carbon out of the air add nutrients to the soil when they die, contributing to rich soil.
Prairie plants are especially adept at storing carbon, locking up large amounts in their roots. In fact, prairies store more carbon below ground than a forest stores above! Deep, complex prairie root systems sequester (store) carbon and – with the help of microorganisms – move it to the soil where it stabilizes.
