Heyy im giving away brainliest. What does cell membrane mean??

Answers

Answer:

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Explanation:

your welcome

The cell membrane is a thin flexible layer around the cells of all living things.

Its basic job is to separate the inside of cells from the outside. In all cells, the cell membrane separates the cytoplasm inside the cell from its surroundings. Animal cells are contained in just a membrane. Bacteria, fungi and plants have strong cell walls as well, which support the cell and block the passage of large molecules.

What are some of the biggest issues concerning gender equality in the
field of business in the United States?

Answers

On average, American women are more educated than men. For decades, women have earned more bachelor’s degrees, master’s degrees, and doctorate degrees than men. Yet women in the U.S. workforce still earn less than their male counterparts. How much less?

While some statistics show that women earn 80 percent of what men are paid, new data published in November 2018 suggests the pay gap between men and women may even be greater.

According to the Institute for Women’s Policy Research, women earn 49 cents compared to every $1 men earn. Unlike other research, the new data considers part-time workers and women who have taken time off from work to shoulder the demands of having and raising children or other family obligations. More than half of women leave the workforce for at least a year, which is twice the rate of men.

To help curb this discrepancy, experts say new policies are needed, including more paid parental leave, support for child care, and other pro-family policies. Here is more information. An obstacle that many women face in the workforce is sexual harassment. While the #MeToo movement has helped to shed light on the issue, little had been known, until now, about how many women are subjected to this type of mistreatment.

A survey conducted in January 2018 by the nonprofit Stop Street Harassment found 38 percent of women have experienced sexual harassment in the workplace, and 81 percent reported experiencing some form of sexual harassment in their lifetime, including verbal or physical assault.

Data also links work-related factors to an increased risk of sexual harassment or assault in the workplace. Women restaurant workers who rely on tips for their main source of income are twice as likely to experience sexual harassment. Women lacking legal immigration status or having only a temporary work visa are also at an increased risk of sexual harassment or assault. Hope this helps! Mark brainly please!

How would you have reacted to segregation in the 1950s?
How do you think segregation made the United States look in the eyes of many in the larger world in the 1950s?

Answers

Answer:

I am a child of the eighties, a child of parents of the sixties. They were both liberals and brought me up to be a liberal who believed everyone was equal. I was brought up on the music of Pete Seeger, Tom Paxton and a bunch of others  it was part of the music of my childhood and it formed a good part of my political ideology.

And if I were to travel back to the 50s now, you can imagine how I would react to segregation  utter abhorrence and disgust and protesting against it as much as possible.

An 1896 Supreme Court decision, Plessy v. Ferguson, had declared “separate but equal” Jim Crow segregation legal. The Plessy ruling asserted that so long as purportedly “equal” accommodations were supplied for African Americans, the races could, legally, be separated. In consequence, “colored” and “whites only” signs proliferated across the South at facilities such as water fountains, restrooms, bus waiting areas, movie theaters, swimming pools, and public schools.

Answers

Answer:

Joseph McCarthy

Explanation:

Senator Joseph McCarthy began the period of McCarthyism in America during the 1940s and 1950s. Many Americans were arrested as accused of involvement as Communist spies. The targets of suspicions were government officials.

McCarthy carried a strong approach with nationalistic in his carrier when he became Judge and then a military officer. During WWII, he was stationed in the Pacific, as an intelligence officer. In America, communism was an important concern as it grew when the Soviet Union expanded its influence in Eastern Europe.

Answers

Answer:

Option: A. Both the Portuguese and the Ming dynasty supported imperial expansion.

Explanation:

Imperial empires in 1450- 1750 expanded using gunpowder, military strategies, cannons, and trade. During this period Europe began to expand and built empires. Some of its empires were the British Empire, the Dutch East India Trading Company, and the Spanish Empire. Beyond the Maritime empires, many land empires emerged like the Ottoman and Mughal Empires.

SAQ help please:
passage: "The Spanish flu was one of the deadliest natural disasters in history—a potent reminder of the threat posed by disease.

Humanity seems to need such reminders often. In 1948, shortly after the first flu vaccine was created and penicillin became the first mass-produced antibiotic, U.S. Secretary of State George Marshall reportedly claimed that the conquest of infectious disease was imminent. In 1962, after the second polio vaccine was formulated, the Nobel Prize–winning virologist Sir Frank Macfarlane Burnet asserted, ‘To write about infectious diseases is almost to write of something that has passed into history.’

Hindsight has not been kind to these proclamations. Despite advances in antibiotics and vaccines, and the successful eradication of smallpox, Homo-sapiens is still locked in the same epic battle with viruses and other pathogens that we’ve been fighting since the beginning of our history. When cities first arose, diseases laid them low, a process repeated over and over for millennia. When Europeans colonized the Americas, smallpox followed. When soldiers fought in the first global war, influenza hitched a ride, and found new opportunities in the unprecedented scale of the conflict.”

"The Next Plague Is Coming. Is America Ready?” by Ed Yong, the Atlantic, 2019


a) Identify ONE environmental factor, alluded to by the author, that is typically present and required for the spread of infectious disease on an epidemic or pandemic scale.

b) Identify ONE specific example of a 20th-century health epidemic that encouraged technological advancement and that is NOT explicitly referenced by the author.

c) Explain ONE specific example of why the optimism of Sir Frank Macfarlane Burnet and George Marshall may have been misplaced.

Answers

Answer:

A) One environmental factor that’s alluded by the author was the movement and migration of different cultures. When one group of people is immune to a certain disease that doesn’t mean all are. As stated in the text “Europeans colonized the Americas, smallpox followed. . . When soldiers fought in the first global war, influenxa hitched a ride”. Different exposure as a whole when it comes to people can make certain people immune to things that others are not, this is usually the cause for many outbreaks of sickness.

B) One specific example of a technological advancement during these pandemics were vaccines. The first vaccine being the flu vaccine after influenza spread, once people found out how to make vaccines other dieseases were easier to handle, polio, smallpox and other sicknesses went from unmanageable to under control once people started to take these vaccines.

C) One reason why Sir Frank Macfarlane Burnet and George Marshall have Mose likely been misplaced is becuase of the statement referenced in the text, “To write about infectious diseases is almost to write of something that has passed into history”. I say this because as we all know, diseases that we have vaccines for are still not 100% preventable. While yes, the vaccines do help manage and greatly decreases the amount of people that suffer from said disease, that doesn’t mean they’re gone. Which makes calling it something that has passed a rather bold claim because while yes the human immune system evolves to fight off certain diseases, there’s no saying that the diseases won’t evolve as well.

Explanation:

I commented on one of the other ones, hope I’m not too late

I got a 95% on this

A) One environmental factor that is typically present and required for the spread of infectious disease on an epidemic or pandemic scale is human migration, as it helps spread diseases that may have been isolated in a particular area to many other areas. The author mentions this in the last paragraph, “When Europeans colonized the Americas, smallpox followed. When soldiers fought in the first global war, influenza hitched a ride, and found new opportunities in the unprecedented scale of the conflict.” This shows that when people moved from place to place, diseases were more easily spread. When you look at previous epidemics and pandemics, and even the pandemic currently going on, one thing is always present: the disease was originally isolated in a single area, and then was later spread through migration.  

 

B) One specific example of a 20th-century health epidemic that encouraged technological advancement was the cholera outbreak in the Romanian Army in 1913. This encouraged technological advancement, as it was within the army during the Second Balkan War, and having an outbreak in the middle of that was very dangerous. As a result, vaccines were quickly produced, systems were put in place that would prevent the spread, the infected were isolated, as well as several other procedures. That is just one of many examples of technological advancements made to stop epidemics.  

 

C) One specific example of why the optimism of Sir Frank Macfarlane Burnet and George Marshall may have been misplaced is because in the end, vaccines only HELP manage the danger to a person, but there’s not a 100% chance of it eradicating it. Also, vaccines can evolve into new strains, ones that vaccines and the human immune system are not prepared for, so simply saying that infectious diseases are something of the past is ignoring that fact. Infectious diseases can come out of seemingly nowhere, so just because the current pandemic is taken care of, that does not mean that it is gone for good.
