The water cycle does not have a real starting or ending point. It is an endless recycling process that involves the oceans, lakes and other bodies of water, as well as the land surfaces and the atmosphere. During the water cycle, water occurs in three different states: gas (water vapor), liquid (water), and solid (ice). Many processes are involved as water changes state in the water cycle.

The steps in the water cycle are as follows, starting with the water in the oceans:

1. Water evaporates from the surface of the oceans, leaving behind salts. As the water vapor rises, it collects and is stored in clouds.
2. As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.
3. Condensation creates precipitation. Precipitation includes rain, snow, hail, and sleet. The precipitation allows the water to return again to the Earth’s surface.
4. When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater. Much of this underground water is stored in aquifers, which are porous layers of rock that can hold water.

Question:

Which of the following statements is true?
- Condensation occurs as water cools in the clouds.
- Precipitation creates condensation.
- It is impossible for water to enter the ground.
- Water occurs in only the liquid state.
A: Condensation occurs as water cools in the clouds.

Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Food is chemical energy stored in organic molecules. Food provides both the energy to do work and the carbon to build bodies. Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis. Only three groups of organisms - plants, algae, and some bacteria - are capable of this lifegiving energy transformation. Autotrophs make food for their own use, but they make enough to support other life as well. Almost all other organisms depend absolutely on these three groups for the food they produce. The producers, as autotrophs are also known, begin food chains which feed all life.

Question:

Where are most autotrophs on the food chain?
- at the bottom
- at the top
- in the middle
- They are not in the food chain.
A: at the bottom

Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons. For example, they provide neurons with nutrients and other materials.

Question:

What do glial cells do?
- provide neurons with nutrients
- run the entire nervous system on their own
- engage in photosynthesis
- turn into neurons
A: provide neurons with nutrients

The function of the circulatory system is to move materials around the body. The circulatory system can be compared to a system of interconnected, one-way roads that range from superhighways to back alleys. Like a network of roads, the job of the circulatory system is to allow the transport of materials from one place to another. The materials carried by the circulatory system include hormones, oxygen, cellular wastes, and nutrients from digested food. Transport of all these materials is necessary to maintain homeostasis of the body. The main components of the circulatory system are the heart, blood vessels, and blood.

Question:

What is one of the main components of the circulatory system?
- heart
- lungs
- hormones
- oxygen
A: heart

The nucleus, which is found exclusively in eukaryotic cells, is a membrane-enclosed structure that contains most of the genetic material of the cell. Like a library, it holds vital information, mainly detailed instructions for building proteins. The nuclear envelope, a double membrane that surrounds the nucleus, controls which molecules go in and out of the nucleus.

Question:

What does the nucleus contain?
- information
- proteins
- the cell
- blood
A: information
