Chapter 1/Quiz

Biosphere The Biosphere consist of all living things kon Earth and the environment that support life from the deepest oceans to high in the atmosphere.
Ecosystem An Ecosystem includes all the living organisms in one particular area( such as African savanna) as well as the nonliving component that affect life, such as soil that affect life and sunlight.
Community A community consist of all the interacting population of organism occupying an ecosystem. This community includes plans, animals, and even microscopic organisms.
Population A population is a group of interacting individuals of one species living within a particular area, such as the African savannah elephants shown here.
Organism An Organism is an individual living being such as one African savannah elephant
Organ system An organ system is a group of organs that work together to perform a vital body function. For example, the circulatory system of a elephant transport needed materials and also water
Organ An Organ consists of multiple tissues that cooperate to perform a specific task. The elephant's heart, for example the elephant hearts pumps blood through the circulatory system.
Tissues A tissues is an integrated group of similar cells that work together to perform a special function.
Cell All living organs consist of cells. Like bacterium have one cell and an elephant have trillions.
Organelle An organelle is a component of the cell that performs a specific function. An epithelial cell's nucleus, for example houses the DNA
Molecule A molecule is a group of atoms bonded togehther.
Atom An atom is the fundamental unit of matter, it is the smallest unit of an element capable of displaying the properties of that element. - Atoms themselve are made of even smaller units called subatomic particles.
Elevolution The scientific explanation for the common characteristics found throughout such diverse species is evolution
Biology Is the scientific study of life
Science Science is the approach to understanding the natural world through inquiry - a search for information, evidence, explanations, and special questions.
Scientific Method is a rough recipe for discovery, a series of steps that, if followed may provide insight about the natural world.
Communication Sharing data Obtaining Feedback Publishing Papers Attending Scientific Meeting Replicating Findings Build Consensus
Exploration Observing Nature Asking Question Reading Scientific Data Seeking Information
Testing Forming Hypothesis Making Prediction running Experiments Conduction Observational Studies Gathering & Analyzing data Drawing conclusion Developing new Hypothesis
Outcomes; Building Knowledge Solving New technologies Informing Policies Benefiting society
Data Recording observation is called Data, which is the evidence upon which scientific inquiry are based.
Hypothesis A Hypothesis is a proposed explanation for a set of observation
Experiment a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
The Process of Science Method Observation Questions Hypothesis Experiment Conclusion Outcomes
Theory A scientific theory is a well substantiated explanation that is comprehensive and able to explain a great many observation.
Fact a fact is a verifiable piece of information considered to be objectively true based on all current evidence.
Controlled experiment To investigate a hypothesis , a scientist may choose to perform a controlled experiment in which a test is run multiple times with one variable changing and ideally all other variables held constant.
Controlled experiment Allows a scientist to draw a conclusion about one variable.
Negative control Is a group for which no changes is expected. For example, switching between two ovens at the same temperature should produce a change in cookies.
Positive control is a group for which a change is expected. For example, doubling the amount of butter should be expected to have an effect. If it does not, the experiment design may be flawed.
Blind experiment information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations,
Single Blind Experiment A type of clinical trial in which only the researcher doing the study knows which treatment or intervention the participant is receiving until the trial is over. A single-blind study makes results of the study less likely to be biased.
double Blind experiment A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over. This makes results of the study less likely to be biased.
Placebo A placebo is anything that seems to be a "real" medical treatment -- but isn't. It could be a pill, a shot, or some other type of "fake" ...
Placebo Image result for Placebo A placebo is used in clinical trials to test the effectiveness of treatments and is most often used in drug studies. For instance, people in one group get the actual drug, while the others receive an inactive drug, or placebo.
