Examine the food web below. Suppose the local government sprayed a pesticide to kill mosquitoes. The sparrows ate the poisoned mosquitoes and died as well. What would most likely happen to the organisms in this food chain after the sparrows began to disappear?
A.
There would be an overpopulation of caterpillars, which would threaten the oak trees.
B.
The sparrows’ disappearance would not affect the other organisms in the ecosystem.
C.
Most of the organisms in the ecosystem would starve and die.
D.
The eagle would loose its primary food source and be forced to start feeding on mountain lions.

Answers

Answer 1

Answer:

A. There would be an overpopulation of caterpillars, which would threaten the oak trees

Explanation:

Because sparrows eat caterpillars as a primary food source, when the population of sparrows decrease, the population of caterpillars will increase. Because of this, more caterpillars will be feeding off of the oak trees, therefore threatening the oak trees. I hope this helps!

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?

Answers

Answer:

There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Why is it that dominant diseases are not as common as recessive ones?

Answers

Answer:

Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?

A. Biome
B. Community
C. Ecosystem
D. Habitat

Answers

Answer:

habitat

Explanation:

The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.

What is a habitat?

A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.

Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.

So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of interacting biotic and abiotic factors in an area

Thus, the correct option is D. Habitat.

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other?

A.One chromosome from each pair randomly passes to the sex cells during meiosis and leads to differences between the siblings.

B.One chromosome from each pair randomly passes to the sex cells during fertilization and leads to differences between the siblings.

C.Mutations occur during meiosis and lead to differences between the siblings.

D.Mutations occur during fertilization and lead to differences between the siblings.

Answers

Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.

Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.

Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.

During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

Her brothers get a chess set for Christmas and she would have to bribe them to let her play with them and little did they know, she would turn out to be a chess prodigy. Throughout the story she faces many obstacles including her moms constant boasting about her and how good she is at chess, and this really angers Waverly because she felt like her mom was trying to control her life and live through her. Amy Tan, in her short story warns that parents should never try to live through their children because it never has a good outcome.Amy Tan is a Chinese-American novelist who was born in Oakland, California on February 19th, 1952. Amy currently lives in Chinatown in San Francisco which is also where her story takes place. She is most famous for her story The Joy Luck Club which was adapted into a movie and is about the relationship between Chinese women and their Chinese-American daughters.Her living in San Franciscos Chinatown plays a major role of her theme of the story. Throughout this story we find out that Waverly and her mom dont have the strongest bond, and in real life Amy and her mom dont either so that helps her with her story. After Waverly runs away and then comes home for dinner her brother tries talking to her about what happened and her mom says We not concerning this girl. This girl not have concerning for us,(Tan, pg.5) her mom is telling her brother not to worry about Waverly because she doesnt worry about them because if she did she wouldnt of ran away like that.Amy Tans stories are based off of the realism era. Throughout her story she shows the realism of mother daughter relationship and how they are never perfect and that its okay to have conflict. She also wrote her story during a postmodern time and this really helps us understand the meaning because its more relatable. She also writes about things that occur in todays society like conflict between mother/daughter relationships.Waverly is tired of her moms boasting, so she tells her I wish you wouldnt do that, telling everybody Im your daughter.'(Tan, pg.5), even though her mom was just being proud of Waverly, she turned it into something thats embarrassing and in todays society a lot of people do that to.Amy Tan, in the story Rules of The Game, is trying to teach us that parents should never try and live through their children because it doesnt have a outcome that anyone will like. This theme is really relevant today because anyone can see it happen anywhere and everywhere. For example, parents will push their children to work very hard at school and make good grades, because they werent capable themselves to do so.In this story Waverly gets into an argument with her mom, and she says, Why do you have to use me to show off? If you want to show off, then why dont you learn to play chess?'(Tan, pg.5), when Waverly says this she telling her mom to stop trying to through her and to stay in her own lane. This idea will be one that will never go away because its been happening for centuries and will continue to happen.In conclusions, people should never live through another person, because it wont turn out the way they would hope to. In the story Rules of The Game, Amy Tan shows us the importance of a mother/daughter relationship, and people should value it. Also how nobody should ever be embarrassed by someone who is proud of them.
