The correct answer is d.
Carbohydrates are a very important part of an athlete's diet, since they provide the necessary energy for competition and endurance, but also help in the process of muscle gain.
The amount of carbohydrates that Shana should consume depend heavily on the intensity of her exercise activities. For a moderate level of exercise, which equals to 1 hour of exercise daily, a person should consume 5-7 g/kg of body weight. For a high level of exercise (1-3 hours of daily exercise), a person should consume 6-10 g/kg.
Guessing that Shana will perform a high level of exercise and based on her weight (135 lb or 61.2 kg), Shana should consume 366 to 610 g of carbohydrates daily.
If a scientist observes an enzyme polypeptide chain arranged in spiral turns that rise upward and are held in place by hydrogen bonds he/she is looking at a tertiary structural arrangement.
<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
Because there is genetic variation among the newly reproduced organism.
