Explanation:
what kind of context clue is
"The hotel abolishes
its rice-all-you-can policy to avoid wastage of food"?
Answer:
Contrast or Antonym Clues
Explanation:
Finding the "context clue" is important in order to know the meaning of a sentence. There are several types of context clues and these are: Definition/Explanation Clues, Restatement/Synonym Clues, Contrast/Antonym Clues, Inference/General Context Clues and Punctuation.
The example sentence above uses the "Contrast/Antonym Clues." It used the word "avoid" which gives you a clue that the meaning of the sentence is opposite to "wastage of food." So this means that "rice-all-you-can policy" is a wastage of food, thus it has to be abolished.

Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not be getting enough oxygen or glucose.
Why does having low levels of glucose or oxygen in his cells make it difficult for Guillermo to walk up steps?
Which body systems should the doctor test in order to find out whether Guillermo’s cells are getting enough oxygen and glucose and why?
Answer:
Oxygen and glucose are both essential for energy production.
Explanation:
Glycolysis is the break down of sugar with or without the presence of oxygen to provide energy to our cells. The energy for the cell is in the form of ATP. In the presence of oxygen the process is much more efficient and is the last step in oxidative phosphorylation. In this process the Oxygen will pick up the protons that have driven the proton motif force that was used to turn the ATPase that was used to make ATP. The oxygen picks up these protons and keeps the cell pH stable and this is called metabolic water. The Dr should check the blood for the presence of both glucose and oxygen.

I"LL GIVE YOU BRAINLEST!! Write an essay about What can you do personally to stop bullying? What can you and your social group(s) do to stop bullying? How can adults help stop bullying?
Answer:
Schools are a primary place where bullying can happen.
Learn what bullying is and what it is not. Many behaviors that look like bullying may be just as serious, but may require different response strategies. You can also learn about what to look for as warning signs that some of your students might be involved in bullying and who might be at more risk for being involved. Know about special considerations for specific groups.
Establish a safe school climate. Often the first step to preventing bullying is making sure the students, teachers, and administrators alike are educated about bullying. Tools like the School Bus Drivers Training and Classroom Teacher Training can help. For kids, tools like these webisodes can help them learn about bullying.
Learn how to engage parents and youth in the building a positive school climate. Learning how to talk about bullying with youth is a critical step.
Know about your obligations under your state’s anti-bullying law. Learn also about federal laws that require schools to address harassment based on race, color, national origin, sex, and disabilities. Work to establish rules and policies to help let the entire school community know the expectations around bullying and procedures to report and investigate when something happens.
Assess bullying in your school and understand how your school compares to national rates of bullying.
Respond when bullying happens. Learn how to stop it on the spot, find out what happened, and support all students involved.
Avoid misdirections in bullying prevention and response strategies.
Utilize free Federal and Non-Federal Resources on bullying.
Parents play a key role in preventing and responding to bullying. If you know or suspect that your child is involved in bullying, there are several resources that may help.
Recognize the warning signs that your child is involved in bullying. They could be being bullied, bullying others, or witnessing bullying. Although these signs could signal other issues, you should talk to your child if they display any sort of behavioral or emotional changes. Many times kids won’t ask for help, so it is important to know what to look for. If your child is at immediate risk of harming himself or others, get help right away.
Learn what bullying is and what it is not. Understanding what bullying is is the first step in forming a plan to prevent or respond to bullying with your child. Many behaviors that look like bullying may be just as serious, but may require different response strategies. You can also learn about:
The frequency of bullying;
Who is at risk for being bullied and bullying others; and
The effects of bullying
Cyberbullying often requires different strategies than in-person bullying. Learn how to work with your kids to prevent cyberbullying and how to respond when it occurs.
Utilize tips and tools to talk to your child about bullying. Opening lines of communication before your child is involved in bullying makes it easier for them to tell you when something happens. It is also important to work with a school to help prevent bullying before it starts.
If you know or suspect bullying has occurred, learn how to find out what has happened with your child. Understanding what has happened can also help in communicating with school or community officials about the situation.
If you have determined bullying has occurred, learn how you and school or community officials can work together to support your child, whether they were bullied, bullied others, or witnessed bullying. Learn also about considerations for specific groups.
If bullying is occurring at school, learn about what your state requires schools to do in your state’s anti-bullying law. Learn also about federal laws that require schools to address harassment based on race, color, national origin, sex, and disabilities and ways to report situations that have not been adequately addressed to the U.S. Departments of Education and Justice.
If you have worked with your child and your school and need additional assistance, find resources to help address the situation.
