Unit 1
The correct format for a hypothesis
If, then, because
A cell is
the smallest unit of an organism
DNA is
the blueprints of a cell, and it's an abbreviation for deoxyribonucleic acid
The theory of evolution was originally thought of by
Charles Darwin, who published a book on his theory of evolution in the 1850's
An example of homeostasis is
1: a gecko sitting in the sun to warm up
2: a plant growing towards the sun
3: a human shivering to warm up
4: a human sweating to release heat
An observation and an inference are different in that
photosynthesis is
the process converting co2 and water into sugar by using sunlight
A genotype is
the genes for an organism, which code for traits
Natural selection is
and artificial selection is
natural selection is the process of an organism that is better suited to its environment surviving better, and thus spreading on its genes to the next generation. artificial selection is when humans naturally breed organisms with traits they like together, so the next generation has these traits carried on.
A physical adaptation is
a structure of the body of an organism to better survive its environment
The difference between quantitative and qualitative analysis is
Quantitative analysis is observations that involve information about the amount of something, which is why it is called quantitative analysis, like quantity. An example is data on a chart showing how many inches a plant has grown. Qualitative analysis is observations on something itself, or it's qualities. An example is saying an apple is red.
At least 3 aspects of life are
1: Life maintains homeostasis, or the condition of keeping itself stable
2: Life reproduces
3: Responds to the environment
4: Processes energy/uses energy in some form
1 parent has a genotype of Tt, and another parent has a genotype of tt. The dominant trait, T, codes for tallness. The most likely percentage of offspring to be tall will be
50%, or 2/4 on a punnett square diagram
Evolution is
the process of an organism changing slowly over generations, which is usually slow and can take millions of years
a behavioral adaptation is
