a. What is the independent variable? Explain why.
Temperature, it is the variable that is being changed
b. The dependent variable? Explain why.
Breathing rate, it is the variable that is being measured and it depends on the temperature
structural levels in biological organization from the simplest
to the most complex level.
2. W hat are the two major dyn amic processes of any ecosystem?
3. Distinguish between prokaryotic and eukaryotic cells.
4. Distinguish between positive and negative feedback.
5. W hat is homeostasis?
equation for photosynthesis
The photosynthesis equation is as follows:
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy from light produces glucose and oxygen
3. How is the movement of energy different from that of nutrients?
Nutrients cycle through ecosystems because the...

A. List the 8 characteristics of all living organisms
1. _____________________________________ 5. _____________________________________
Microorganisms are classified according to their structure. By means of flow charts, diagrams and tables explain the differences between Viruses, Bacteria, Cyanobacteria, Achaea and Fungi.
Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form...

Lesson 02.01: Chemistry of Life
· Explain why biological macromolecules are important for everyday life.
Cells make large macromolecules by bonding smaller molecules together into chains called polymers (from the Greek polys, "many," and meris, "part"). Polymers are large...

BI 111 Study Guide
Exam #1: Some of Ch. 4, the brief discussion summarizing Ch. 6, and Chptrs. 5, 7, and 8
HOW TO USE THIS STUDY GUIDE: You should be able to provide fairly detailed answers to the following questions and directions… this means you will probably use more room than is provided...
Preliminary - Stage 6
2 Unit Biology
8.2 - A Local Ecosystem:
1. The distribution, diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors: Distinguish between the abiotic and biotic factors in the environment:
– – – – – – Biotic Factor:...
so small as to be invisible or indistinct without the use of the microscope
Macroscopic – visible to the naked eye
Biodiversity – variety of life within an area (generally increases from Earth’s poles to the equator)
Homeostasis – the maintenance of constant internal conditions in an organism
3.5.1 The student will analyze the relationships between biotic
diversity and abiotic factors in environments and the resulting
influence on ecosystems.
1.4.6 The student will describe trends revealed by data.
3.3.3 The student will explain how...
another species for resources such as food, water, or territory
➢ Biomes – major types of ecosystems that occupy very broad geographic regions.
➢ Photic zone is where there is enough light for photosynthesis to occur and an aphotic zone, where very little light penetrates.
➢ Benthic zone - is...
require energy, involve reduction, and lead to an increase in atomic order.
anaerobic Refers to organisms that are not dependent on oxygen for respiration.
analogous structures Body parts that serve the same function in different organisms, but differ in structure and embryological development; e...
environmental phenomena. Chemistry is applied to understand the molecular interactions among natural systems. Biology is fundamental to describing the effects within the plant and animal kingdoms. Environmental science encompasses issues such as climate change, conservation, biodiversity, groundwater and soil contamination...
Translate proteins by reading an amino acid chart.
Photosynthesis and cell respiration are complementary processes for cycling carbon dioxide and oxygen as well as transferring energy in ecosystems.
During photosynthesis, cells trap energy from sunlight with chlorophyll and use...
diversity of life from genes to ecosystems and spans every level of biological organization. The term has several interpretations, and there are many ways to index, measure, characterize, and represent its complex organization. Biodiversity includes species diversity, ecosystem diversity, genetic diversity...
What is Life?
In this chapter we will learn how living organisms change as they become better adapted to their environment. Over millions of years, these changes have produced a large number of different kinds of organisms. It has been estimated that there may be 10 to 30 million or more...
