Question 202 pts
Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration?
Group of answer choices

The function of photosynthesis is to use solar energy to make ATP; the primary function of respiration is to break down ATP to release energy.

Photosynthesis only occurs in heterotrophs, while cellular respiration only occurs in autotrophs.

Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time.

Photosynthesis uses solar energy to create organic molecules; cellular respiration breaks down organic molecules to make ATP.

Answer 7

Here are the correct answers to your questions regarding the Middle Passage and the Atlantic slave trade:

Question 1: What were enslaved captives fed during the Middle Passage?

• Answer: Small rations of rice, millet, beans, or cornmeal.
  (Enslaved captives were given meager rations often consisting of these basic staples, which were insufficient to maintain their health.)

---

Question 2: What is the Atlantic slave trade considered in terms of migration?

• Answer: Involuntary migration.
  (The Atlantic slave trade involved the forced transportation of enslaved people against their will.)

---

Question 3: What was the justification for using the tight packing method of loading enslaved persons onto ships?

• Answer: To increase the number of enslaved reaching their destination.
  (The tight packing method was a strategy used to maximize profit by loading more enslaved individuals onto ships, even at the cost of their health and safety.)

---

Question 4: How long did the Atlantic slave trade last?

• Answer: From the early 1500s to the mid-1800s.
  (The Atlantic slave trade is generally considered to have begun in the early 1500s and continued until the mid-1800s, varying by region and specific countries involved.)

---

Question 5: Why did European powers start the Atlantic slave trade with domains in West Africa?

• Answer: To acquire enslaved Africans who were more resistant to disease than Native Americans.
  (This was one of the main reasons, as European colonizers found that enslaved Africans were more resilient to diseases like malaria and yellow fever compared to Native Americans, who suffered high mortality rates.)

Answer 8

whats a suicide bombing

Answer 9

A suicide bombing is an act of terrorism in which an individual detonates explosives that they are carrying, often resulting in their own death as well as the deaths or injuries of others. This tactic is typically used by individuals or groups to achieve a specific political, ideological, or religious goal, and it is designed to instill fear, promote a cause, or retaliate against perceived enemies.

Suicide bombers usually target civilian areas, public gatherings, or institutions, and the attacks are planned to maximize casualties and generate media attention. The motivations behind suicide bombings can vary widely, including extremist beliefs, political grievances, or a desire for vengeance.

It's important to note that suicide bombings are a form of violence that is condemned by many individuals and organizations, including numerous religious and political leaders who advocate for peaceful resolutions to conflicts.

Answer 10

so basically wanting to kill themselves but also others

Answer 11

Yes, that's a concise way to put it. A suicide bombing involves an individual who is willing to sacrifice their own life by detonating explosives, often with the intent to kill others. The motivations behind this act can vary widely, including:

• Ideological or Political Beliefs: Some individuals carry out suicide bombings as a form of protest or to promote a particular political, religious, or ideological agenda.
• Desire for Vengeance: They may seek to retaliate against perceived enemies or injustices.
• Peer or Group Pressure: Individuals may feel compelled to act as part of a militant group, sometimes seeing the act as a form of martyrdom or honor within their belief system.

While the bomber is intent on dying, the act is primarily aimed at causing harm to others, thereby instilling fear and drawing attention to the cause they are associated with.

Answer 12

do people still do those

Answer 13

Yes, unfortunately, suicide bombings still occur in various parts of the world today. While the frequency and public awareness of such attacks may fluctuate over time due to geopolitical factors, ongoing conflicts, and extremist groups, suicide bombings continue to be employed as a tactic by certain terrorist organizations.

Some regions where suicide bombings have been more prevalent include:

• Middle East and North Africa: Areas with ongoing conflicts, such as Iraq, Syria, and Yemen, have seen numerous suicide bombings carried out by groups like ISIS, Al-Qaeda, and others.
• South Asia: Groups in countries like Afghanistan and Pakistan have also resorted to suicide bombing as a tactic in their violence.
• Sub-Saharan Africa: Groups like Boko Haram in Nigeria have utilized suicide bombings in their insurgency.

These attacks often target civilian populations, military personnel, government officials, or places of worship to instill fear and convey a message related to their causes. Anti-terrorism efforts, including improved security measures and community engagement, are continually being developed to combat and prevent such acts of violence. However, the underlying issues that contribute to extremism, such as political instability, inequality, and social disenfranchisement, remain complex challenges that need addressing to reduce the incidence of such attacks.
