This level of organization indictes groups of the same type of cell that all work together to serve a specific funtion.
What are tissues? (or, what is a tissue)
100
This biomolecule is responsible for long-term energy storage.
What is a lipid?
100
The structure responsible for molecular transport is this.
What is the cell (or plasma) membrane?
100
This enzyme unzips DNA, which is the first step in DNA replication.
What is helicase?
100
DNA holds the template for making proteins, but it can't leave the nucleus. This biomolecule takes the DNA code to the ribosome:
What is mRNA?
200
Monomers are smaller parts of a larger molecule (called a polymer). Molecules then make up this level of biological organization:
What is a cell?
200
Proteins are a polymer that can be found in muscle, bone, and enzymes. This is the monomer that makes proteins:
What is an amino acid?
200
The cell membrane is made up of a phospholipid bilayer, which means there are two layers, and that the biomolecules in that layer are:
What are, protein and lipid?
200
DNA must replicate itself during this phase of the cell cycle, otherwise during mitosis, the daughter cells will not have enough DNA.
What is interphase (S Phase)?
200
mRNA codons will pair up with a tRNA anti-codon to help make a protein chain; tRNA brings this biomolecule to the mRNA in order to build this protein.
What is an amino acid?
300
The entire system of all living things is called this.
What is the biosphere?
300
Lipids, which can be found in the cell membrane, are made up of these two parts:
What is a glycerol and 3 fatty acids?
300
This type of transport allows large molecules to enter or leave the cell through protein channels. This type of diffusion also does NOT require energy.
What is facilitated diffusion?
300
The cell cycle is made up of interphase (which has 3 parts), and this 4-part phase:
What is mitosis?
300
Protein synthesis consists of two parts; this part takes place in the ribosome.
What is translation?
400
The levels of biological organization work together to create systems of life. This level could be represented by the following examples: heart, lung, flower, stem, liver, brain.
What are organs?
400
Carbohydrates provide quick energy for the body and are made of simple sugars. The technical term for these sugars is:
What is "monosaccharide?"
400
Prokaryotic cells differ from Eukaryotic cells because they do not have:
What is a nucleus (or membrane-bound organelles)?
400
When the cell cycle is disrupted, the cell will continue to divide even when the cells are tightly packed together. The name for that condition is:
What is cancer?
400
The process of translation occurs in this organelle because DNA is not mobile, so mRNA must carry the message to the ribosome.
What is the nucleus?
500
Since all levels of biological organization are made up of the levels "below" them, these are the levels that would make up an organism:
What are: organ systems, organs, tissues, cells (and molecules and atoms)
500
Enzymes, which are proteins, work in the body to make chemical reactions (like digestion) more efficient and easier. Enzymes make this happen by:
What is lowering the energy required to start the reaction (activation energy)?
500
The job of muscle cells is to provide energy for the body, so they have more of this organelle (which is the "powerhouse" of the cell):
What are mitochondria?
500
The last part of the cell cycle occurs when the cytoplasm is completely separate and the cell membrane pinches closed to create 2 separate daughter cells. The name for this phase is:
What is cytokinesis?
500
Mutations that cause the reading frame (or "window") to shift--and to code for different amino acids--occur during replication. The types of mutations that could happen are:
