Courtney S. 4th Period SINKERS and FLOATERS Purpose:The purpose of this investigation is to provide an overview of photosynthesis and to design and conduct an experiment to test the factors that affect the rate of photosynthesis. Hypothesis:If 10 leaf discs are placed into 2 plungers and placed under a lamp the CO2 rate will speed up the process of photosynthesis. Materials: -Fluorescent lamp - Hole punch - 1 Sharpie marker -20 leaf discs -Syringes -12 mL cups Data Table Start 2 4 6 8

Endocrine Disruptors in the Environment Endocrine disruptor can be found in products that we use on a daily basic such as plastic bottles‚ cosmetics‚ detergents‚ toys‚ can foods‚ and pesticides. These disruptors are chemical that at specific dose may interfere with the body’s endocrine system‚ which in order can produce hostile neurological‚ developmental‚ immune‚ and reproductive effects in the human body. Disruptors can work in may ways such as impersonating a natural hormone‚ blocking the effects

The Endocrine System Exercise 1: The Pituitary Gland obseRvations A. Please describe in detail the structures and features you observed on the pituitary gland slide. The Pituitary Gland Slides The Anterior Pituitary Gland was darker than the Posterior Pituitary Gland. In the Anterior Pituitary Gland Slide you can see Chromophobes and Acidophiles. Not super easy to distinguish which is which though. The Posterior Pituitary Gland slide showed Pitulcytes (Neuroglia) as light purple

it was not until my first test in AP Biology‚ that I realized I actually had to go the extra mile and put forth maximum effort into studying and reviewing. I needed a biology mentor like Mrs.Ciasulli to bring out the best in me because she knew of my aspirations to work in the medical field. Although she attempted to make my life as difficult as possible‚ she made me fall in love with the material and gain much more appreciation for the study of biology. AP Biology then became the class I was most

Through endocrine signaling‚ the signaling molecule or hormone is produced by a gland and discharged into the blood where it travels until it reaches certain blood cells distant from its place of origin on which it exerts its action. This is a long distance communication process. The signaling molecule is mainly of protein origin‚ although there is also a varied range of steroidal hormones.

The Demographic Transition One attempt to summarize an observed voluntary relationship between population growth and economic development is the demographic transition model. It traces the changing levels of human fertility and mortality presumably associated with industrialization and urbanization. The first stage of that replacement process-and of the demographic transition model-is characterized by high birth and high but fluctuating death rates. As long as births only slightly exceed deaths
