Unit 1
How to form a proper hypothesis.
Make a prediction based on observations that can be experimented.
What do plant cells have that animal cells do not?
Cell walls, chloroplasts, and chlorophyll.
What defines active transport?
Transport that uses energy by going against the concentration gradient.
How do cancer cells form?
From errors within the cell, DNA gets messed up during cloning in mitosis and the checkpoints that would destroy the cell are destroyed so the faulty DNA continues to clone.
_____ is the genetic makeup of a trait, while _____ is the physical form of the genetic trait.
genotype ; phenotype
Zero on the PH scale.
What is an acid?
Who created the name 'cell'?
Robert Hooke.
What is diffusion?
When particles move from areas of higher concentration to areas of lower concentration in an attempt to reach equalibrium.
In which step of mitosis does the cell split into two new cells?
Telophase.
The _________ was scientific research project to map the entire DNA of a human in use to find out how genetic disorders form.
Human Genome Project.

-wear gloves when handling substances
-dont touch chemicals
Cell membranes are ______, which means ________.
semipermiable ; only certain substances can enter and exit the cell if the membrane allows it.
What is a hypertonic solution?
When the concentration is greater inside of the cell than outside of the cell, water will move out of the cell and cause it to shrivel.
What is known as the "programmed cell death" that occurs when errors in cloning are sensed.
Apoptosis.
What are the two possible genotypes for type B blood?
