DNA
What is the function of DNA?
It stores and transmits genetic information that determines traits and directs cell activities.
Name the four biomolecules.
Carbohydrate, Lipid, Protein, and Nucleic Acid.
The diffusion of water across a selectively permeable membrane is called ____.
Osmosis
All cells can be classified into one of two categories. What are those two categories named?
Prokaryotic and Eukaryotic
Give an example of a lipid.
FAT, WAX, OIL, CHOLESTEROL, STEROIDS, PHOSPHOLIPIDS
What is complementary to the DNA sequence A-T-G-C?
T-A-C-G
Which biomolecule provides QUICK and SHORT-TERM energy?
Carbohydrate
What is Endocytosis
When a cell takes in a large molecule by forming a vacuole around it and moving it into the cell.
What do viruses need to replicate?
A living host.
What is homeostasis?
A self-regulating process by which a living organism can maintain internal stability while adjusting to changing external conditions.
The sides (backbone) of the DNA ladder are made of these two components.
Sugar (deoxyribose) and phosphate
Membrane. (Phospholipid bilayer)
Which type of cellular transport requires ATP Energy.
Active Transport
Which two biomolecules make up a virus?
Nucleic Acid and Protein.
The movement of molecules from an area of high concentration to an area of low concentration is called ____.
Passive Transport/Diffusion
What does DNA replication produce?
Two identical DNA molecules, each with one original strand and one new strand
What is the difference between a monomer and a polymer?
A monomer is a single unit of a biomolecule. A polymer is a chain of monomers.
What are two examples of passive transport?
Simple Diffusion
Osmosis
Facilitated Diffusion
What is one major difference between a virus and a cell?
Viruses are not made of cells and cannot reproduce on their own.
How do molecules enter and exit the cell.
What are the components of a nucleotide?
Phosphate group, Deoxyribose sugar, and Nitrogenous Base
What is the main function of an enzyme AND how does it do it?
Speeds up chemical reactions within the body by lowering the activation energy.
When an animal cell is placed in a hypertonic solution, what will happen to it?
It will lose water and shrink.
What is the protective outer layer of a virus that surrounds its genetic material called?
The Capsid
When you miss Biology class, what is the classroom policy?
You check the missing work station and ask Mrs. Marquez if necessary outside of class time. Complete missing work within three school days.
