Erika was not among those who disliked Mr. Kelp. As point guard, she was the best passer on the team. She was also the only one not worried about passing science. Her B in Mr. Kelp's class was her lowest letter grade overall. Still, she appreciated how he challenged the class. He didn't let students skate by with minimum effort. Erika considered his class to be good preparation for college. She made plans to meet Mr. Kelp before school. She wanted to ask if he would hold a special study session to help the team prepare for the exam. Her teammates were not fond of the idea. According to Erika, her teammates did not see the point in a study session. They insisted that there was not enough time to learn everything. They were going to fail and get kicked off the team. The season was going to end in embarrassment. Then, one of the teammates spoke out. Erika would not reveal which teammate it was, but she remembers the words clearly. "Our only chance is for someone to get a copy of the test so we know the answers ahead of time." The team smiled. They felt like they had been offered some hope. Erika frowned. She felt like she had been given an order. Erika tried protesting for a while, but she felt trapped. "As soon as the idea was out there, everyone jumped on it," Erika explained. "They kept telling me it would be easy. That I could save the season. That a real teammate puts the team first." Before she knew it, the team had drawn up a plan. Erika would visit Mr. Kelp's room the following morning. Someone would create a distraction down the hall. When Mr. Kelp investigated, Erika would grab a copy of the test from his desk. Erika wanted to say no, but between championships and friendships, there was too much to lose if she did. The following morning, Erika stood in Mr. Kelp's room with her hands shaking and her teeth chattering. She snatched a blank test as he stepped into the hall. What happened next is a blur—partly because it happened quickly—mostly because Erika would like to forget it ever happened at all. She was called to the office, her backpack was searched, and the test was found. By the day's end, she had apologized to a shocked Mr. Kelp. She had been removed from the team by a disappointed coach. She had been suspended by an angry principal and driven home by tearful parents. Wanting to be a good teammate, Erika never mentioned the other players. She expected them to step up and admit their involvement. She ended up taking the fall alone. Her teammates avoided her, saying they were happy the cheater was off of the team. With the exam postponed, they were treated as heroes for winning the championship without her. Erika transferred to another school, remembered as the girl who cheated to make straight A's. Today, a star athlete and college scholar, Erika blames past mistakes on no one but herself. The ball is in her hands again. This time she plans on making better decisions. In paragraph 1, we learn that Erika has an A in every class other than science. What sentence in the paragraph shares this fact implicitly? (5 points) She was also the only one not worried about passing science. Her B in Mr. Kelp's class was her lowest letter grade overall. Still, she appreciated how he challenged the class. He didn't let students skate by with minimum effort

BRAINLIEST FIRST CORRECT ANSWER HELP!!!!! Recent surveys around the world have found some very sad and troubling news. Bees are not doing well. According to Time: Science & Space, "an estimated ten million beehives ... have been lost since 2006." What's worse, scientists are not sure why. Most beekeepers will tell you that bees tend to die in large numbers every spring. This is normal and necessary to keep a hive of bees healthy. But when the deaths add up to more than half the bees in an entire country, that is something altogether different and dire. Scientists have called this "colony-collapse disorder" or CCD. This name describes the effect, though, and not the cause of the die-out. Scientists simply do not know what is killing the bees. Many things make it hard for bees. Varroa mites move into a colony and weaken it. Further, these mites carry viruses that attack those that survive. In addition, a new bacterium was recently discovered that attacks bees intestinally and kills them. Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. All these attackers and the methods used to combat them do stress the bees, however. Many feel the problem is not some new threat, but a decline in the habitat available to bees. Development of grasslands once home to wild flowers and food for bees has been universal. Pavement makes it easy to drive, but it replaces wild grasses and other food sources for bees. Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health. We plowed under a varied habitat and planted—in many cases—a single plant like beets. Then we sprayed all kinds of chemicals on the beets to keep other bugs away and in doing so also harmed bees. Now, to treat all the mites and other invaders, bee keepers use additional chemicals to kill the invaders. These chemicals also shorten the life of the bees. Have the use of chemicals, loss of habitat, and invading parasites made life impossible for bees? Experts continue to argue various theories, but few have any answers. Colony collapse disorder is perhaps one of the most mysterious problems modern science has tried to solve. Whether the problem is environmental or an unknown disease, we will all feel the effects if bees continue to decline. Bees affect almost every aspect of the human food chain. From the fruits, vegetables, and grains we eat, to the grasses and grains we feed our livestock, we depend on bees to keep us healthy. According to the Natural Resources Defense Council, bees account for 15 billion dollars in crops. Honey is a treasure for sure, but the real gold is in the strawberries, apples, peaches, and green beans we eat and need to stay healthy ourselves. All told, the outlook for bees is not good. The outlook for humans may not "bee" so good either. Read this section of the text: Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. What does the phrase great lengths mean in this sentence? Dangerous steps Difficult times Extreme efforts Simple solutions

WILL GIVE BRAINLIEST!!! NEED HELP ASAP!!!!!!!! IT'S JUST 2 QUESTIONS!!!! 1. Read the following paragraphs to prepare for placing them in the correct order. Before one can even think about becoming an astronaut, the first step is to apply. Applicants must have at least a bachelor’s degree in engineering, mathematics, biological or physical science. They must also have three years of experience and/or an advanced degree. Those that meet these qualifications are individually screened. The Astronaut Selection Board then makes its recommendation of candidates. All in all, astronauts have a very demanding job. They must not only prove themselves worthy of being accepted for training, but they must actually endure the extensive training program. Once in the job, their work becomes even more demanding as they conduct precious research to share with the world. Because of this, becoming an astronaut is a highly demanding but profoundly rewarding career. Have you ever wondered what it would be like to travel to space? An astronaut’s job seems like a very grand adventure. However, being an astronaut is not easy. Astronauts have a hard job because they must endure a difficult application process, go through extensive training, and conduct comprehensive studies and experiments. After an applicant has been accepted into the Astronaut Candidate Program, he or she will undergo one to two years of training. Candidates attend classes on various subjects including shuttle systems, astronomy, oceanography, and many science and technology courses. Furthermore, the candidates need to learn some basic survival skills, especially survival swimming. Furthermore, they experience what it feels like to be weightless and learn how to maneuver in these conditions. Finally, they undergo formal training in which they learn via simulation software that mimics an actual shuttle voyage. Finally, all the courses, simulations, and survival skills the candidates have learned will be put to the test. Another reason why an astronaut’s job is so difficult is because she is expected to not only maneuver through space, but she is expected to conduct research and experiments in space. Because of this, astronauts must be keenly observant, alert, and continually use common sense. In order for an astronaut’s research to be accurate, it is important to use proper procedures for collecting data. An astronaut’s work in the field requires a high degree of intelligence as well as physical stamina. Place the paragraphs in the correct order to form a basic 5-paragraph essay by choosing the first few words of each paragraph from the boxes below. Introductory paragraph begins: Body paragraph 1 begins: Body paragraph 2 begins: Body paragraph 3 begins: Concluding paragraph begins: (the answers to where the paragraph begins is NOT the first sentence for ANY of them!) 2. Which three main sections are found in any type of essay? A. thesis statement, body paragraph #3, and introduction B. body, conclusion, introduction C. transitions, body paragraph #2, and body paragraph #3 D. supporting details, thesis statement, MLA documentation Oh, if you can't answer both, it's okay. Can you at least try to answer 1 of them? Thanks!
