Cell Cycle, Mitosis, Meiosis
The phase where DNA replication occurs
Synthesis (s phase)
A movement of ions and other molecular substances across cell membranes without the use of need of energy is what kind of transport?
What is passive transport
What vein carries water up to the leaves?
Xylem
What do all cells have in common? (Think of structure)
DNA
The concept that organisms who are the best suited to their environment will be the most successful in reproduction and passing on their genes.
Natural Selection
Step where the cytoplasm splits.
Cytokinesis
What monomers are the basic units of proteins?
Amino Acids
Which organisms have the most available energy in a food pyramid?
Producers
What are the 4 bases of DNA?
The legs of crocodiles and wings of a bat have similar bone structures. What type of structures are they? (Evolution)
homologous structures
During which phase of both meiosis and Mitosis do the chromosomes line up at the middle?
Metaphase
A biomolecule that serves as a fast source of energy.
Carbohydrates
These small holes are responsible for the gas exchange between Oxygen and Carbon Dioxide.
Stomata
A T C C G T G A T G A A G A C
T A G G C A C T A C T T C T G
Genetic Drift
The process by which chromosomes cross each other resulting in a variety of genes.
Crossing Over
When the outside has a higher solute concentration, water moves out.
Hypertonic
What are the products of cellular respiration?
Water, Carbon Dioxide, ATP Energy
Deoxyribose
A brown bear and a polar bear were once the same species but then they started to look different. What kind of evolution occured?
Divergent
If a Mouse has 30 chromosomes, how many does its sperm cell have?
15
Made of mostly phospholipid molecules embedded with proteins, this flexible boundary regulates what goes in or out of the cell
Cell Membrane
Photosynthesis Formula
CO2 + H2O —> C6H12O6 + O2
What part of the DNA is responsible for coding genes?
Nucleotides (sequence of bases)
Some fossils in a record abruptly changed from small shells to big pointy shells. What was the rate of change in evolution that occurred?
Punctuated Equilibrium
