100
The phase where DNA replication occurs
Synthesis (s phase)
100
a movement of ions and other atomic or molecular substances across cell membranes without need of energy input but requiring a protein channel
What is passive transport, specifically facilitated diffusion
100
How does our genetic material lead to traits being expressed?
DNA --> RNA = TRANSCRIPTION
RNA--> amino acid chain = polypeptides = proteins = traits = TRANSLATION
100
Name two processes occurring during meiosis that lead to genetic diversity.
crossing over prophase 1
1/2 the chromosome number in daughter cells
independent alignment of chromosomes during metaphase I and II
100
If the producers contain 10,000 Kcal how much energy do the secondary consumers receive
100 Kcal
200
Name a characteristic of a virus that would make them considered "living".
- has DNA
- has a way to reproduce
- mutates/changes over time
- changes its reproduction type based on environmental conditions
200
What monomers and atoms make up proteins?
amino acids are made of CHON (proteiNNNNNN)
200
Which organisms have the most available energy in a food pyramid?
Producers
200
What are the products of cellular respiration?
water and carbon dioxide, but most importantly ATP
200
An oak tree has 120 chromosomes in its leaf cells. How many chromosomes would you find in the pollen cells?
60
300
What cell parts are required to make the most basic of cells?
cytoplasm, cell membrane, ribosomes, DNA
300
What is the purpose of mitosis?
To make identical copies of body cells for growth, repair, and asexual reproduction
300
During which phase of both meiosis and mitosis do the chromosomes line up at the middle?
Metaphase
300
A biomolecule that serves as a fast source of energy?
What are carbohydrates
300
A plant cell has 1% solute concentration. A student puts the cell into a 0.9% solute solution. What will happen to the cell?
Water will enter the cell causing swelling. The cell will be turgid, and the solution is hypotonic.
400
Type of succession where no soil present
Primary Succession
400
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
400
Name 2 environmental conditions that can denature enzymes
pH, temperature
400
process by which plants break down glucose, without the use of oxygen, to create ATP
Anaerobic cellular respiration in plants is alcoholic fermentation
400
Two organelles contained in a plant cell but not an animal cell
Cell wall, chloroplast, (central vacuole)
500
What does it mean if a molecule is "fixed" for use by cells?
It is usable. For example, the carbon in CO2 is fixed for use in living cells in C6H12O6
500
The formula for photosynthesis
CO2 + H2O —> C6H12O6 + O2
500
Define incomplete dominance
When both alleles are present they will mix to create a new phenotype/trait
500
Find the Amino Acids
TAC - AGT - ATT
DNA: TAC - AGT - ATT
RNA: AUG - UCA - UAA
Amino Acids: MET - SER - Stop
