Biology IB Study Guide 1: Communities and Ecosystems 5.1 Communities and Ecosystems (Core) 5. 1. 1 Define species‚ habitat‚ population‚ community‚ ecosystem‚ and ecology. Species – A species is a group of organisms with similar characteristics‚ which can interbreed and produce viable‚ fertile offspring. Habitat – A habitat is the environment in which a species normally lives or the location of a living organism. Population – A population is a group of organisms of the same species‚ who

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in this case a half). This means that as the light moves away then there is less light given to the reaction for photosynthesis to happen

board of the Millennium Ecosystem Assessment. "Human activity is putting such strain on the natural functions of Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted‚" it said. Ten to 30 percent of mammal‚ bird and amphibian species were already threatened with extinction‚ according to the assessment‚ the biggest review of the planet’s life support systems. "Over the past 50 years‚ humans have changed ecosystems more rapidly and extensively

Introduction: Trying to find a good‚ quantitative procedure that students can use for exploring photosynthesis is a challenge. The standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. This is a particular problem if your laboratory instruction emphasizes student-generated questions. Over the years‚ I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

Without oxygen‚ life itself would be nonexistent. Imagine what would happen if wounds did not get better‚ incisions did not heal‚ and burns did not improve. This is where hyperbaric oxygen therapy (HBOT) comes into play. Oxygen is necessary for the replenishment of tissues‚ healing of the body and assisting with general ailments. HBOT is used for a wide variety of treatments usually as requested in a medical care plan (Society‚ 1996). In this paper I will introduce what hyperbaric oxygen therapy

The atmosphere is full of different smells‚ it all depends where you are locate. I live here on William Paterson campus and I smell a lot of different odors. If you go into the diner hall‚ where the food is bein starved you get a smell of different kinds of food. The smells can vary from pizza to burgers or pasta and sometimes in the morning it smells like waffles. When you arrive in my dorm building‚ it does not have much of a smell beside when they mop the hall way. Sometimes the hallway smells
