input with options: Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . This lesson focuses on the role of the kidneys in excretion. The roles of the other excretory organs are summarized below:. Q: Excretion is the process of removing excess water and wastes from the body. what are the main organs of excretion? A:
OPTIONS:
- eyes
- lungs
- brains
- kidneys
output: kidneys

Q: Answer the following question given this paragraph: Introduction Breathing is an involuntary event. How often a breath is taken and how much air is inhaled or exhaled are tightly regulated by the respiratory center in the brain. Humans, when they aren't exerting themselves, breathe approximately 15 times per minute on average. Canines, like the dog in Figure 39.1, have a respiratory rate of about 1530 breaths per minute. With every inhalation, air fills the lungs, and with every exhalation, air rushes back out. That air is doing more than just inflating and deflating the lungs in the chest cavity. The air contains oxygen that crosses the lung tissue, enters the bloodstream, and travels to organs and tissues. Oxygen (O2) enters the cells where it is used for metabolic reactions that produce ATP, a high-energy compound. At the same time, these reactions release carbon dioxide (CO2) as a by-product. CO2 is toxic and must be eliminated. Carbon dioxide exits the cells, enters the bloodstream, travels back to the lungs, and is expired out of the body during exhalation. Q: What gas is expired out of the body during exhalation? A:

OPTIONS:
- carbon monoxide
- hydrogen
- oxygen
- carbon dioxide

A: carbon dioxide

input: OPTIONS:

Answer the following question given this paragraph: Pressure is defined as the amount of force pushing against a given area. How much pressure a gas exerts depends on the amount of gas. The more gas particles there are, the greater the pressure. Q: What is the amount of force pushing against a given area? A:

OPTIONS:
- inertia
- power
- energy
- pressure

Answer: pressure

Problem: OPTIONS:
- carbon cycle
- sedimentation cycle
- photosynthesis
- nitrogen cycle
Q: Answer the following question given this paragraph: 3.4 NITROGEN: RUNNING IN CYCLES Introduction: In the previous assignment, you studied the carbon cycle. In a previous unit, you described the water cycle. Carbon and water are matter. As you learned in the first unit, matter cycles. Nitrogen is another form of matter that cycles. Like water and carbon, nitrogen is essential to life. Also, like water and carbon, its cycles affect you. Therefore it is important that you learn about the nitrogen cycle, how it affects you, and how you affect it. Assignment: There are three parts to this assignment. You must complete all three parts to receive credit for the assignment. Be sure to turn in all three parts at the same time. I will not correct partial assignments. THANKS! PART ONE: 1. Describe the nitrogen cycle. Describe how nitrogen goes from the atmosphere to a form usable to plants, how it is used and excreted by animals, and how it returns to the atmosphere. In your description be sure to explain the words: * decay * denitrification. Q: What cycle vital to plants includes a process called denitrification? A:
Answer: nitrogen cycle

Answer the following question given this paragraph: Light slows down when it enters water from the air. This causes the wave to refract, or bend. Q: What causes light to refract? A:

OPTIONS:
- speeding up
- blinking
- bending
- slowing down

Answer:
slowing down
