The cell membrane, or plasma membrane, is made up of a lipid bilayer in which hydrophilic heads face outward and hydrophobic tails face inward. This arrangement within the cell membrane allows it to A. control the movement of substances in and out of the cell. B. keep out all viral and bacterial infections. C. fuse with ribosomes during DNA replication. D. absorb water from the cytoplasm whenever necessary.

Answers

Answer 1

Answer:

The correct answer is A. control the movement of substances in and out of the cell.

Explanation:

All cell membranes are made up of lipids and proteins. Lipids are organized in two closely adjoining sheets that form a lipid bilayer. This bilayer provides the basic structure of the membrane and acts as a permeability barrier (impermeable) for most water-soluble molecules. Cells live and grow by exchanging molecules with the surrounding environment and the plasma membrane acts as a barrier that controls the transit of molecules into and out of the cell. As the interior of the membrane (the lipid bilayer) is hydrophobic, the membrane tends to block the passage of almost all water-soluble molecules (which dissolve in water). Protein molecules, which are normally “dissolved” in the lipid bilayer, act as mediators or facilitators of almost all membrane functions, either by transporting specific molecules through it or by catalyzing membrane-associated reactions, such as synthesis of ATP.

Answer 2

Answer:

control the movement of substances in and out of the cell

Explanation:

Write 3-5 sentence summary of the events that occurred at the Tiananmen Square. You can write it from the point of view of a protester or a government official. Make sure you let me know which one you choose.​

Answers

Answer:

Tiananmen Square incident, also called June Fourth incident or 6/4, series of protests and demonstrations in China in the spring of 1989 that culminated on the night of June 3–4 with a government crackdown on the demonstrators in Tiananmen Square in Beijing. Although the demonstrations and their subsequent repression occurred in cities throughout the country, the events in Beijing—especially in Tiananmen Square, historically linked to such other protests as the May Fourth Movement (1919)—came to symbolize the entire incident.

Which group of sentences in this candidate’s platform is a reasoned judgment?

Annie Suzuki
Hello, everyone! I’m Annie Suzuki from the seventh grade. I’ve served on the student council for two years. I’ve also been on the teacher appreciation committee for the school. My experience on the council and the committee has helped me establish a dynamic and positive relationship with students and teachers at our school. As president, I wish to become a strong voice for all students. I also want to bring about certain changes in our school.

For starters, we should have longer lunch periods. We’ve all experienced being stuck in the lunch line for so long that we have to rush to eat our food. We often don’t have time to finish! This is bad for our health. Longer lunch periods will give us some extra time to eat our food in peace.

Next, I think the junk food available in our vending machines isn’t good for us and should be replaced with healthy snacks. It’s important for us to eat nutritional food and develop good eating habits while we’re young.

Another important change that I think we need is keeping the library open for more hours. We don’t have enough time to study at home. And some of us need the computer access the library provides. Therefore, a few extra hours of library services each day will help us improve our grades.

I perfectly understand the significance of the needs of students, and I’m open to new ideas. I feel that I have it in me to become a good, responsible student body president. Thank you!

Why might Gorbachev have chosen to allow private businesses only on a small scale?

Answers

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Gorbachev might have chosen to allow private businesses only on a small scale because it was the first serious transition from a Communist economy to a Market economy in years. So it was such a delicate step to open the country to private and foreign investment.

After many years under the Communist regime, the Soviet Union split in December 1991. During those Communist years, the USSR never allowed private property in the Soviet United. The state was the owner of the means of production.

So when Gorbachev decided to implement glasnost and perestroika reformations, he had to carefully proceed because these involved some kind of risk.

The Soviet Union ceased to exist on December 26, 1991. Gorbachev had resigned one day before and the new leader of Russia was Boris Yeltsin.

D.

(Psychology)

Answers

Answer:

A

Explanation:

Got it right on edge

Based on the scenario, the most likely outcome according to the concept of social traps is the fishermen will begin to fish more often, depleting the local fish supply. The correct option is A.

What is the social trap game theory?

A phenomenon known as "social traps" in social psychology refers to a circumstance in which a single person or group of individuals act or operate for short-term reinforcement or gains, but have a propensity to over-exploit a resource, ultimately resulting in a loss for the group as a whole and to society.

This is because the fishermen are likely to engage in a competition trap, where they will compete with each other to catch as many fish as possible, in fear that there will not be enough fish left for them. As a result, they will over-fish the area, leading to a depletion of the local fish supply. The lack of communication among the fishermen may exacerbate this problem.

Thus, the ideal selection is option A.

Effects on relations between Muslims and Christians

Answers

Muslim-Christian relations so as to give context to current “hot spots” of Muslim-Christian conflict in the world. It is also important to understand the ways in which members of the two communities experience each other in specific areas of the world today, including the United States, taking note of efforts currently underway to advance interfaith understanding and cooperation. The events of September 11, 2001, and the resulting American invasions of Iraq and Afghanistan, have led to ugly commentary reminiscent of medieval hyperbole. Right-wing evangelical rhetoric in the United States against Islam has been fueled by incidents of international terrorism involving Muslims, while the well-funded Islamophobia industry in the United States has been producing and distributing large amounts of anti-Muslim material. Since the events of September 2011, American Muslims, caught in a painful position, have decried the acts of the 9/11 terrorists and defended Islam as a religion of peace. American Muslims want to exercise their constitutional rights to free speech in expressing their objection to certain American foreign policies, at the same time that they fear the consequences of the Patriot Act and other acts they view as assaults on their civil liberties. Meanwhile other Americans are struggling to understand that the Muslims with whom they interact in businesses, schools, and neighborhoods are different from the Muslim extremists who are calling for ever more dire measures against the United States. This is the general context in which Christian-Muslim dialogue is now taking place and to which it must address itself if it is to be effective.

Explanation:

I don't think it could have survived. Rome was a very unstable republic, which was a problem. Since the fall of Carthage, one powerful individual after another has emerged, challenged the Senate and other powerful individuals, and put the Republic in danger.

Could the Roman Republic survive?

Even while the populace made an effort—or at least the senators did—it simply could not endure, leading to the Third Civil War and the reign of Octavius, later known as Augustus. Also worth mentioning is that the Roman populace believed that the Roman Republic still existed. Its final downfall in 27 BCE was a result of economic issues, political corruption, criminal activity and private armies, the advent of Julius Caesar as tyrant, and other factors.

Rome's continuing growth brought the Republic money and revenue. In order for government officials to advance in authority and acquire access to this money, corruption and bribery increased. Votes were purchased and friends were given favors by the wealthy. Corruption and widespread bribery helped the commoners.
