Characteristics of life
Living Organisms can produce offspring either sexually (2 parents genes together) or asexually (single parent)
What is Reproduction?
Smallest unit of life
What temperature water is better at dissolving substances
Warm water
In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable
What is experimental group
Strongest kind of chemical bond that 2 atoms share at least one pair of outer electron shells. Also shares or donates electrons to other atom if needed
(Hint Sharing is Caring)
What is Covalent bond
Living things use and process energy by carrying out chemical reactions to grow, repair, and maintain themselves
What is Metabolism? (AKA energy processing)
A group of similar cells working together to perform a specific function
What is Tissue?
Which type of substances CAN NOT be dissolved by water and why?
Hydrophobic because of non polar molecules
A testable prediction, an educated guess
Hypothesis
This bond is weak but important and creates a v-shape. Also atoms are attracted to each other because of this being polar and two atoms being slightly negative and the other atom slightly positive.
What is a Hydrogen Bond?
Organism maintain a stable internal environment
What is Homeostasis
A community of living things interacting with non-living physical environment
What is Ecosystem?
The ability to retain energy in the form of heat
The ability for a substance to resist changes in state
What is heat capacity?
The measurable effect, outcome, or response in which the research is interested
What is Dependent Variable?
This is a bond that is attracted to each other's charge which allows the bond to hold together. Bond may gain or lose 1 or more electrons.
(Hint: We eat an example of this bond everyday)
What is an Ion Bond
Living things detect and react to changes in their external or internal environment
(Hint an example is Fight or Flight mode)
What is Response to Stimuli
A group of organism of the same species living in the same area
What is Population
Why does water have a high heat capacity
Information describing color, odor, shape, or some other physical characteristic
What is Qualitative Data?
Left side - increasing acidity (H+)
Right Side - Increasing in base (OH-)
In the middle is Neutral
Every unit change is by 10x
What is the pH scale
Populations of living organisms change and adapt over generations through natural selection to better survive in their environment
What is Evolution and Adaption
All different population species interacting in a given area
What is community
The temperature in Celcius is when water is most dense and what form (solid, liquid, gas?)
What is, 4 degrees Celcius in liquid form
A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions
(Hint this is a summary)
What is the Scientific Method
When H20 rises up against gravity and uses Cohesion and Adhesion
What is Capillary Action?
