Write a paraphrase of the following passages.1. Bats are in the limelight these days because they are rumored to be the source of COVID-19, the virus that caused the coronavirus pandemic. But that is just part of their story. Bats turn out to be miraculous creatures. Their ability to age without decrepitude or cancer, as well as fight off a multitude of infections, are giving us clues about how to do the same for ourselves.

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. It contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. Nearly every cell in a person's body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases…

Nucleotides appear in nucleic acids, as coenzymes in metabolism, and as chemical messengers. One example of the last is cyclic-adenosine monophosphate, CAMP, where the phosphate group forms a ring with two of the ribose carbons. Which of the following represents CAMP NH₂ HO N 0 OH OH HOW HO OH NH NH₂

A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? O The number of adenine bases will be equal to the number of guanine bases. O The number of adenine bases will be equal to the total of all the other bases. O The number of adenine bases will be equal to the number of thymine bases. O The number of adenine bases will be half of the number of cytosine bases.

For years we’ve been told that eating fat will cause various health problems and have been warned to eliminate it from our diet. But now we know that not all fat is the same. By understanding the difference between good and bad fats and how to include more healthy fat in your diet, you can improve your mood, boost your energy and well-being, and even lose weight. Since fat is an important part of a healthy diet, rather than adopting a low-fat diet, it’s more important to focus on eating more beneficial “good” fats and limiting harmful “bad” fats.   What is their experience with the health risks associated with ‘bad fat’ intake for example obesity, diabetes, heart disease, strokes, cancer, etc.? Why is eating healthy so important?   What are are recommendations for maintaining a healthy diet of ‘good fats’? What's the deal with fats?

The World Health Organization (WHO) recommends us to limit "free sugar" intake to no more than 5 % of the total daily Calories consumed. Sugars like sucrose are considered "free sugars" and provide about 4 Calories per gram. If an individual consumes 2000 Calories in a day, what is the maximum amount of sugar they are advised to take in? How does this amount compare to the added sugars found in popular soft drinks?

Based on a grade 11 chemistry student, answer the following question based on the provided tables: Part G:  Final Identification of the Poison By this time, Tylenol has been pulled off the shelves at all of the stores in the area and a nationwide recall has been announced.  Several suspicious capsules have been found and tested.   The contents of the capsules contain a compound with a nitrogen content of greater than 15% and a carbon content of less than 50%.   What is the poison in the capsule?  Provide calculations to support your answer.

A piece of news reported that Jenjarom, a town located in the Kuala Langat District, is now smothered in 17,000 tonnes (17mil kg) of plastic waste. There were 33 illegal factories in Kuala Langat, the district Jenjarom is located in. Some sprang up nearby dense palm oil plantations, whereas others were closer to town. The smell started a while ago but got worse around August this year. People in the town started to feel unwell and would keep coughing. These illegal recycling plants choose to dispose of plastic a cheaper way - either burying it or burning it causing fumes - so hazardous that some people even coughed up blood clots while some could not sleep at night because of the smelly air. Children were also affected, especially those who lived nearest to the factories in Jenjarom. There were reports some children developed really bad rashes around their stomach, neck, legs, and arms. Their skin would keep peeling, even when touched by people, and hurtful. The smell was far and wide…

One of the most common types of kidney stones are composed of calcium oxalate. In addition to calcium oxalate another product is also formed in the formation of kidney stones in the body. Certain foods are high in oxalate and lead to an increase of forming kidney stones in the human body. These high-risk foods are as follows:   Spinach Swiss Chard Almonds (nuts in general) Sesame Seeds Soy Products (such as soy-based milk, cheese, yogurt) Sweet Potatoes Okra Beets Chocolate Black Tea   Another risk factor to developing kidney stones is not drinking enough water. Males have a higher chance than females of developing kidney stones, with the average age being 30. Oxalate in food binds to calcium during digestion in the stomach and intestines and then is excreted in the body as waste. If too much oxalate appears in the urine and not enough liquid (due to not drinking enough water), then calcium oxalate crystals form, which are the kidney stone.  A 35 year old male was taken to the hospital…
