Ap Biology Prompt

1. An understanding of chemistry is important for an understanding of biology because biology needs the models of chemistry to better describe life.

Human impact on the cycling matter in ecosystems can change a lot of things. Humans can either help or hurt things. The carbon, nitrogen and phosphorus cycles are the three cycles of matter in ecosystems. What are these cycles? How do humans effect each one of these individual cycles? What are some examples of humans effecting these cycles?

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

Surface Tension: The measure of how difficult it is to stretch or break the surface of a liquid.

3a. Body more than five times as long as broad; front edge of dorsal fin far

1. The anatomical region found between the lungs that extends from the sternum to the

Carbohydrates: any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.

The final 2 property points were earned for the description and discussion of specific heat.

1) The layer of the GI tract wall that is responsible for motility is the

1. Information transfer is fundamental to all living organisms. For TWO of the following examples, explain in detail, how the transfer of information is accomplished.

My sisters and I love to go shopping, we then have lunch together when we’re done

diluted enough that they are no longer a problem. Of all the water on the earth,

Natural changes in energy reaching Earth from the sun and the amount of heat retained by Earth are causing more changes than humans are causing (EPA). Humans are not doing as much damage as we think we are. Natural changes and catastrophes cause more problems for the Earth than humans do. An example is the change in the Hydrological Cycle (Scott). The water, or hydrologic cycle, is the continuous movement of water on and below the Earth. The changes in precipitation by the sun are causing fresh and salt water to mix. “The water cycle over the past century with a combination of natural variables” (EPA). The water cycle has caused more rainfall than snow. Another cycle that changes Earth's temperature is the sun cycle. “The sun cycle is a cycle that is eleven years long that causes small effect, but the changes in shape of the orbit and the tilt of Earth’s axis affect the amount of sunlight each region gets”(Earth Observatory). This regulates how much of the sun’s energy reaches the Earth. This causes the atmosphere and the magnetic field to change which makes the atmosphere stronger; therefore changing the temperature of the planet to a warmer state. The atmosphere could be going through those changes now which are causing many more changes in

Water… For many reasons, water cycle is important to all life on Earth. The water cycle describes the process of how the water moves through the Earth into human uses and to all living organisms need water to grow and to survive. The water cycle has no starting point, but ocean is where most of Earth’s water exists. In an ecosystem, water cycles through the atmosphere, oceans, rivers, soil and lakes.

All water in nature goes in a cycle , it is called the water cycle. The water cycle replenishes itself by evaporating the water out of the ground and then condensing in the clouds, then releasing the water back to earth through in the form of rain, this is called precipitation. Saltwater and freshwater is what power life on earth.
