Classification of Organisms
All living things maintain an internal balance of conditions, also called __________.
The organelle where aerobic respiration takes place and ATP is produced.
mitochondria
Where does replication take place in the cell?
the nucleus
This nucleic acid contains nitrogenous bases adenine, thymine, guanine, and cytosine.
DNA
This cell structure is made of a double layer of phospholipids, and controls what enters and leaves the cell.
cell membrane
A cell viewed under a powerful microscope has a cell membrane, ribosomes, cilia, and no visible nucleus. What type of cell is it?
prokaryotic
Which organelle, found in the rough ER, synthesizes protein?
This is the longest stage of the cell cycle.
interphase
Transcribe the following DNA sequence: GAT
CUA
This is the building block of protein; each codon is translated into one of these.
amino acid
A virus is made of genetic material and a protein coat. It is not made of _______, classifying it as non-living.
cells
Sodium is moved from a lower concentration outside the cell to a higher concentration inside the cell. What type of transport is taking place?
active transport
metaphase
Translate the following: AGU GAC
serine - aspartic acid
A phylogenetic tree can be used to show this.
common ancestry, or evolutionary relationships
A gray wolf's scientific name is Canis lupus. What taxonomic level is "lupus"?
Aerobic respiration produces more ATP than anaerobic respiration. Aerobic respiration can only take place if ________ is available.
oxygen
After the cell cycle has finished with cytokinesis, the resulting daughter cells are ________________.
identical
What molecule is responsible for reading the mRNA message and transferring in amino acids that will form a protein?
Insertions and deletions are examples of what type of mutation?
frameshift
Kingdom Fungi is made up of eukaryotes that are mostly multicellular, have a cell wall of chitin, and share what other characteristic?
heterotrophic
When placed in this type of solution, a cell will swell.
hypotonic
This is an enzyme that helps separate double-stranded DNA so that it can be replicated during the cell cycle.
DNA helicase
Sometimes an error in a DNA sequence can result in a stop codon during translation, instead of the correct amino acid. What is this called?
a nonsense mutation
carbon dioxide
