Scientific Method
Scientists use more observations after posing questions in order to make an inference. It is a statement that can be tested by scientific research. (what are you testing)
What is inferring and forming a hypothesis?
A tested and highly reliable scientific explanation of events in the natural world that unifies many repeated observations and incorporates hypothesis
What is a theory?
Requires time and energy to find mate and reproduction takes a longer period of time
What is a disadvantage to sexual reproduction?
The science that employs scientific methodology to study living things (the study of life)
What is biology?
Two types: sexual and asexual
What is reproduction?
Whether the hypothesis supported or rejected. This may lead to more questions
What is interpreting data and drawing conclusions?
Type of data that is descriptive and involves characteristics that cannot usually be measured. Ex. Notes about whether a plant was growing upright or sideways
What is qualitative data?
Scientist share their hypotheses, experimental methods, results, and analysis with other scientist in scientific journals who review them and look for mistakes, oversights, unfair influences, or fraud. The goal is to ensure scientific articles meet the highest standards of quality
What is peer review?
A decimal system of measurement whose units are based on a certain physical standards and are scaled on multiples of 10
What is the metric system?
Most organisms must keep internal conditions including temperature and water content fairly constant to survive (homeostasis)
What is maintaining internal balance?
A hypothesis should be tested by an experiment where only one variable is changed and all other variables should be kept controlled (how you are testing)
What is designing controlled experiments?
A tentative scientific explanation that can be tested by further observation or experimentation
What is a hypothesis?
Reproduction is quick, and there is no need to find a mate
What are advantages to asexual reproduction?
Reproduction in which the new organism is produced from a single parent. The offspring and their parents have the same traits
What is asexual reproduction?
DNA is a molecule that carries the directions for inheritance in organisms
What is the universal genetic code?
Scientific investigations begin with the act of noticing and describing events or processes in a careful, orderly way
What is observing and asking questions?
Numbers obtained by counting or measuring. Ex. Number of plants per plot, the length and width of a blade of grass
What is quantitative data?
A personal, rather than scientific, point of view for, or against, something such as preferences for or against certain kinds of people or activities
What is bias?
Small, self-contained units that are complex and highly organized. The smallest unit of an organism. Grows responds to their surroundings, and reproduces
What is a cell?
An organism uses energy and a constant supply of food, water, etc to grow, develop, reproduce, and stay alive
What is the need for materials and energy?
Results and manipulation of the test quantitative and qualitative data
What is collecting and analyzing data?
Group that is exposed to the same conditions as the experimental group except for changes in the independent variable
What is a control group?
Leads to genetic variation in new generations of offspring which is fundamental to evolution. Also produces genetic diversity
What are advantages to sexual reproduction?
Cells from two different parents unite to produce the first cell of the new organism. Offspring differ from their parents in some traits
What is sexual reproduction?
Organisms detect and respond to external and internal stimuli (ex. thirst, hunger, temperature)
What is response to the environment?
