John recently had his visual acuity measured using the Snellen Eye Chart. His results indicated that his vision is 20/15 in both eyes. Which answer best describes what 20/15 vision means? *

Answers

Answer 1

Answer:

The answer is below

Explanation:

Snellen Eye Chart was developed in 1862 by Dutch ophthalmologist Herman Snellen, to determine if humans have a normal vision which is rated at 20/20

However, in the case of John, a 20/15 vision means John can see a line in the eye chart at 20 feet away that the average person can only see when they are 15 feet away.

This shows John has a sharper than average visual acuity.

Rice is an example of an energy-giving food because it contains carbohydrates. Therefore, option C is correct.

What is a balanced diet?

When a diet contains all kinds of nutrients, then it is called a balanced diet.  Coffee, tea, and cola drinks do not belong in the food pyramid guide. Margarine is found at the top of the food pyramid.

Increased consumption of fatty foods is not healthful to do. Adolescents require more energy and nutrients because they need to achieve full growth potential and their bodies are preparing for pubertal changes. It is unhealthful to eat foods high in fats and sugar because these are major risk factors for developing chronic diseases, such as heart disease and diabetes.

To stay at a healthy weight, one should choose a healthful diet with fiber from fruits and vegetables. Eat plenty of grains, vegetables, and fruits because these provide important vitamins and fiber. adolescents need 2 glasses of milk and 1 egg daily.

In this book, at least 20 kids are stranded on an island with no grownups, only themselves. They have to learn how to survive without adults and chaos plays a big factor in this novel. Throughout the book they make rules and try to stay organized, but they ultimately cannot deal with themselves without the outside world and become leviathans. The conch, the beast, and the hunting show the boys descent into savagery.The conch shows many themes all through this book. Though, the most frequent theme is how it did more harm than good. In the beginning of LOTF it shows how the conch created some organization in the group. This conch is the only thing that keeps them from tearing each other apart. Even Jack Merridew, who was known for causing turmoil respected the conch, He laid the conch with great care in the grass at his feet (22). Yet, towards the end of the book, the conch caused a few bad things to happen. The rock struck Piggy a glancing blow from chin to knee; the conch exploded into a thousand white fragments and ceased to exist (181). In this quote, Roger with a sense of delirious abandonment pushed down the lever so that the rock would come down and cause a ruckus. I theorize that Roger had felt left out of all the madness happening below him, that he had to do something to put attention on him. This shows, that the conch causes lunacy. The attention was on Piggy because he had the conch, therefore because Roger did not have the conch he felt left out and craved attention, and it drove him to do something drastic. Whoever holds the conch always has the attention on them. Piggy says, I got the conch, I got the right to speak (44). In this quote, the boys let the fire go out and Piggy has something to say about it. No one likes to listen to Piggy, but because he has the conch it is only fair that they listen to him, since that is the rule. Ralph made the rule that whoever has the conch has the right to speak and everyone has to listen. Democracy was established with the conch. Overall, the conch caused quite a lot of bad things to happen. you have $63.50. you earn additional money by raking leaves. you purchase a sweatshirt $44.99 and you have $53.51 left. how much money did you earn raking leafs? what is the name of the molecular compound SF
