Answer:

These are the basic steps of urine formation.

Explanation:

The first step comprises creating a filtrate in the glomerulus.

During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed.

Waste products will then be secreted by the tubules.

Whereas, the final stage is the conservation of water that occurs in the renal tubule.

There are four major stages in the formation of urine.

2 Chapter 1 ■ The Food You Eat

1 The Food You Eat

Have you ever wondered how the food you eat fuels your body?

Why some foods make your body feel and perform better than others? Nutrition has the answers. The more you know about nutrition,

the better you will be able to make food choices that will keep you

healthy and strong and keep your body functioning optimally.

Adequate nutrition can help prevent certain diseases, maintain an

optimal body weight, and give you more energy to participate in the

activities you enjoy. There are six essential nutrients in the human

diet. Take a look at what’s on the menu in your school cafeteria

today, and see if you can identify items that contain these nutrients.

In This Chapter,

You Will . . .

■ Understand the science of

nutrition

■ Learn how proteins, carbohydrates, and fats comprise the

foods you eat

■ Learn about the benefits of

vitamins, minerals, and water

■ Discover what calories are and

how they are calculated

■ Learn about food additives

such as flavor enhancers,

preservatives, and coloring

A group of scientists studying vegetation in a mountain range observe that a certain flowering plant grows taller at lower eleva

UkoKoshka [18]

Well, first of all, the question asks us to to list three different factors that could lead to this variation.

The first one is pressure, so, what happens is that, when the pressure changes with the height change, these plants develop in different ways. The second one is the oxygen, as we know, oxygen in higher elevations is less than in ocean elevation for example, so this can be a reason for this variation. The last one is the quantity of organic material on the soil, this can influence directly on the development of this population.

With that said, we need to write a hypothesis for one of these factors, let's choose the organic material because it's easier and cheaper to test. For that, the hypothesis is that, with less organic material available on the ground, the plant will grow smaller than on a normal soil. To test that, we need to grab samples of this flowering plant and put it at the same conditions as on the mountain, that is a possibility on a good lab, so after that, we'll change the quantity of organic material on some samples, to check if my hypothesis is right or not.

The positive results are that this is the reason why the plants grow smaller, so, with less organic material, the plants won't develop in the same way as it would happen with enough organic material. The negative results are that this is not the reason why these variations exist, so we need to test another factor to check why this variation is happening.
