Nucleus of a cell
The brains of the cell. This is in the middle of the cell, and is where the cell dna is located
Cytoplasm
Surrounds and protects the nucleus
Ribosomes
Synthesizes biological proteins
Mitochondria
Place where energy is converted by the cell into fuel
Eukaryotic cells
Membrane-enclosed nucleus, includes plant and animal cells
Prokaryotic cells
No membrane around the DNA, includes bacteria
Actin
The skeleton of the muscle
Myosin
The motor of the muscle
ATP
Produces the energy our body needs
Phosphate
PO4H2
Diffusion
When particles spread out and equalize their concentrations
What covalent bonds store the energy for plants
Glucose and diatomic oxygen
What type of light is a CO2 rich atmosphere opaque to
Infrared light
Genotype
The internally coded, inheritable information carried in the DNA of all living organisms
Phenotype
The outward, physical manifestation of an organism. It results from a combination of genotype, which is inherited, plus many environmental factors
Dominant
A gene that produces the same phenotype in the organism even if the corresponding gene from the other parent is different. For example, the gene for brown eyes is dominant
Recessive
A gene that produces a phenotype in an organism only if the corresponding gene from the other parent is the same. For example, the gene for blue eyes is recessive
Homozygous
An organism is homozygous for a given trait if both of the corresponding genes for that trait are the same
Heterozygous
An organism is heterozygous for a given trait if both of the corresponding genes for that trait are different
Positive feedback
A continuous amplification of heat
Negative Feedback
A gradually decreasing amount of heat
Sexual selection
A form of natural selection in which individuals with certain traits are more likely than other individuals to obtain mates
Sustainable
Permanent and nothing is harmed
Renewable
Things are harmed and it isn’t permanent
How many atoms are in a simple sugar ring
23 atoms, 6 Carbons, 11 Hydrogens, 6 Oxygens, 4 hydroxyl groups, two simple sugars are bonded by an Oxygen atom
Bilateral symmetry
A definite head
Radial symmetry
Five-fold symmetry
Sodium Potassium pump
The mechanism by which a sodium atom enters a cell
Coefficient for diatomic oxygen in photosynthesis
6
DNA to RNA
Transcription
DNA coding for amino acids
Translation
C6H12O6 + (6)O2 =
(6)CO2 + (6)H2O
(2)C8H18 + (25)O2
(16)CO2 + (18)H2O + kinetic energy + heat energy
K-T boundary
A distinct layer of clay found in rocks formed from sediment that blanketed the earth 66 million years ago, at the end of the Mesozoic and the beginning of the Cenozoic era. This boundary can be found in the Raton Basin. Below the K-T boundary, the fossils are larger and more diverse. Above the K-T boundary, the fossils are smaller and less diverse
Critical piece of evidence that an asteroid struck earth and wiped out the dinosaurs
Rocks taken from the Chicxulub crater are the same age as the K-T boundary
How could an asteroid kill off so many species
The sun being blocked out, thereby halting photosynthesis
How a meteor could be stopped
Solar power, flying laser bots could go into space and zap off tiny pieces of the asteroid. In this way, the momentum of the asteroid would be changed and the asteroid would change course.
Formula for sodium oxide
