how many steps are there in the scientific method
what is 7
is this living?
what is no
what is water made up of
what is ... 2 hydrogen and one oxygen atom
The process by which a stable internal environment is maintained despite changes in the external environment.
is a tomato a fruit or a vegetable
what is a fruit
variable is the variable that is changed by a scientist in an experiment.
what is the independent variable
is this living? (yeast)
what is yes
what is the bond that holds water molecules to another water molecule
what is a hydrogen bond
define negative feedback
what is Response triggered by changed conditions serves to reverse the change
what does the Scoville scale measure?
what is spiciness
This variable is what is measured by a scientist in an experiment.
Scientists determine the experiment outcome with this variable.
what is a dependent variable
what is the definition of biology
what is the study of life
what is it called when 2 molecules of water are attracted to eachother
what is cohesion
define positive feedback
The response triggered by changing conditions serves to move the variable even further away from its steady state
what is the process called by which plants use light from the sun to produce energy for life?
what is photosynthesis
a group of subjects in an experiment that is not exposed to the variable being tested, and is used to compare results to the experimental group
what is a control group
which of these is not a characteristic of a living thing:
Made of cells (one or more)
Displays organization
Grows and develops
Reproduces
Responds to a stimulus
being able to move/relocate
Requires energy
Maintains homeostasis
Evolves over time
what is: being able to move/ relocate
what is it called when the combined force of attraction among water molecules and with the molecules of the surrounding material cause water to move against gravity ( move upwards)?
what is capillary action
give an example of a negative feedback loop
what is maintaining pH, blood pressure, temperature, heartrate...ect
what is the most basic unit of life
what is a cell
Determine the IV and DV in this scientific question:
Does the amount of sunlight a plant receives affect the plant’s height?
IV: amount of sunlight
DV: plant height
One characteristic of living things is that living things have a level of organization. define levels of organization
what is The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere
Define polarity and explain why water is polar
molecules that have a uneven distribution of charge across their structure resulting in one side being positive and the other side negative
water has one positive end and one negative end
give an example of a positive feedback loop and explain
what is child birth
what is the hardest substance in the human body
what is tooth enamel
