Base your answer on the passage below

Avian (Bird) Flu

Avian flu virus H5N1 has been a major concern recently. Most humans have not been exposed to this strain of the virus, so they have not produced the necessary protective substances. A vaccine has been developed and is being made in large quantities. However, much more time is needed to manufacture enough vaccine to protect most of the human population of the world.

Most flu virus strains affect the upper respiratory tract, resulting in a runny nose and sore throat. However, the H5N1 virus seems to go deeper into the lungs and causes severe pneumonia, which may be fatal for people infected by this virus.

So far, this virus has not been known to spread directly from one human to another. As long as H5N1 does not change to another strain that can he transferred from one human to another, a worldwide epidemic of the virus probably will not occur.


3.Identify one event that could result in the virus changing to a form able to spread from human to human.

Answers

Answer 1

As the virus goes from bird-to-bird and bird-human. The  virus may become unstable enough and mutate like crazy. One of those mutations could be like lethality or severity, But more important, human-human spreading.

In what way is the cell membrane like a gatekeeper? (The picture It just because I wanted to put it TwT)

Answers

The membrane is a gatekeeper as it only allows access to selected nutrients or cells, if it wants one type of nutrient to process, it will only choose that nutrient!

Hope this helps, if not, comment below please!!!!

Answer:

The cell membrane controls how materials move into or out of a cell, just like a gatekeeper controls the flow of traffic into and out of a parking lot. Movement of substances through a cell membrane WITHOUT using the cell's energy ; includes diffusion, osmosis, and facilitated diffusion.

Explain your observations on what organisms need to grow. Explain how human activity can impact an organism’s ability to obtain the resources it needs to survive. State your opinion about how human activity can be changed to have less impact on the lives of other organisms.

Answers

Answer:

All living organisms need food, water, and shelter in order to grow and survive. Human activities can have a lot of impacts on different organisms; whether they’re good or bad. Humans may take away natural habitats for some by expanding into a previously untouched area. In the same sense, they might end up accidentally providing a food or water source. Although there is some good, humans should limit and change their activities in order to have a less impact on the lives of other organisms. We could create more national or state parks, which would make a safe haven for a lot of organisms. We could impose stricter punishments for people for litter as it harms organisms. We might create nature preserves in order to force humans to leave alone the other organisms in a certain area. Overall, we play a big role in a lot of different organisms lives and we need to make sure it’s a positive one.

Hope this helped, all written by me so no plagiarism(:

Explanation:

Human activity is a major threat to the planet's biodiversity. This is because human population growth thus far has been exponential, meaning that its growth rate stays the same regardless of population size. This makes the population grow faster and faster as it gets larger.

Populations may grow exponentially for some period, but they ultimately reach a carrying capacity when they become limited by resource availability. Humans, however, have continued to work around carrying capacity as they develop new technologies to help support the ever-growing population. This threatens biodiversity because the more humans there are, the more this displaces other species and reduces species richness. Human-mediated causes of biodiversity loss.

What are the two types of anaerobic respiration? Describe the two in one paragraph.

Answers

Answer:

The two main types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.These strategies of respiration occur while the amount of oxygen available is simply too low to guide cardio respiratory.Alcoholic fermentation converts glucose into ethanol. In alcoholic fermentation, glucose is broken down via glycolysis, and two ATP molecules are released in the method. The pyruvic acid molecules produced for the duration of glycolysis destroy down into ethanol and carbon dioxide. In animals, the technique of lactic acid fermentation, further, happens after the glycolysis process. Pyruvic acid is changed into lactic acid, and muscles is damaged down through lactic acid.

Explanation:

The two types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.

Explain  anaerobic respiration

Some microbes, including yeast, can ferment alcohol. This procedure transforms glucose into ethanol and carbon dioxide. Through a sequence of biochemical processes, glucose is turned into pyruvate, which is then transformed into ethanol.

On the other hand, lactic acid fermentation takes place in different types of bacteria and human muscle cells. Lactic acid is produced during lactic acid fermentation from glucose. When there is a shortage of oxygen, such during vigorous exercise when muscle cells are unable to receive enough oxygen for aerobic respiration, this process takes place. Although lactic acid fermentation results in an accumulation of lactic acid, which can contribute to muscle discomfort and tiredness, it also helps renew the NAD+ molecules required for glycolysis to proceed.

Censorship: Who Should Decide What Young People Read?
(Take a Stand!!!)

Support your position with clear reasons and specific examples. Follow the debate guidelines discussed in class.

access | civil | despite | integrate | promote

Answers

Answer:

No one should decide what anyone reads but ourselves. People, now matter how young or old, should be able to make the decision by themselves. If they want to read Manga, Horror books, Romance, Suspense, Mystery, Graphic Novels, Sci-Fi, Fantasy, Nonfiction, Narrative, Genre Fiction, Historical Nonfiction/Fiction, Poetry, Thriller, Biography, Memoir, Autobiography, Short Story, Literary Fiction, Science Fantasy, Paranormal Romance, Fairy Tail, Myth, Folktale, History, Adventure Fiction, Textbook, Prose, Fantasy Fiction, Magical Realism, Erotic Literature, Historical Romance, High Fantasy, True Crime, Occult Fiction, what ever they want to read they should be able to access them. Now I'm not saying young children's minds shouldn't be protected. For example, if I were to take your privilege of reading away and say that you are only allowed to read Fantasy books, despite your age, that would not be right and would cause civil disputes in the literary world. We should promote a cause that enables any aged children, especially young minds, to be able to pick from the entire literary universe. We shouldn't force people to integrate into books that we want, instead into books that everyone wants. In conclusion, no one should decide what we read but ourselves.

Both Hutton and Lyell claimed that Earth was very old and changed very slowly over time.

Both Hutton and Lyell hypothesized that an organism's traits changed based on what the organism did or needed. The improved trait was then passed on to its offspring.

Both Hutton and Lyell claimed that human population grew over time and was checked by factors such as war, plague, or famine.

Answers

Answer:

The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.

Explanation:

During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

Today organisms are generally different from their ancestors in the fossil records because of the concept of evolution.

Evolution has caused ancient organisms to change drastically from their present day cohorts.

Although, some similarities exists and they can help tell how the organisms have evolved, nonetheless, ancient life forms are much different. Paleontologists use evidence from a diverse source to interpret fossils in order to show relationships between organisms.
