Heredity and Hormones and How They influence Behavior There are many things that are unknown about the reasons behind people’s thoughts and actions‚ but in recent years‚ concepts about how a person’s own genetic make-up and hormones can affect our own behavior. Although there have been no breakthroughs that can definitively say this hormone causes people to act one way all the time‚ there have been instances where a person’s genetics and hormones can contribute to certain behavioral ideas. There

Nitrogen cycle A simple and complete diagram of the nitrogen cycle. The blue boxes represent stores of nitrogen‚ the green writing is for processes that occur to move the nitrogen from one place to another and the red writing are all the bacteria involved. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation

1. Explain how adaption relates to our thermoreceptors and touch receptors. How we feel cold only when something cools or warms the thermoreceptor and not by the absolute temperature. We are accustomed to a particular level of warmth and adapt to it. What is referred pain and how can it be dangerous? Referred pain is when something‚ usually internal organs‚ cause some other part of the body to feel the pain. It can be dangerous if someone with a heart attack have pain in their arm‚

The Nitrogen Cycle The Nitrogen cycle is the exchange of nitrogen gas in the earth’s atmosphere and living organism’s. Nitrogen is a necessity to all living organisms in their production of proteins‚ DNA‚ and RNA in their cells . However‚ only a few organisms can use this gas directly‚ due to the fact that it may limit the growth of plants. Nitrogen takes up about 78% of the earth’s atmosphere. The nitrogen cycle has three main chemical transformations‚ including nitrogen fixation‚ nitrification

Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division
