What organelle controls what enters and leaves the cell?
cell membrane or plasma membrane
Who developed the theory of Natural Selection?
Charles Darwin
Organisms that make their own food. They perform photosynthesis
autotrophs or producers
The word means balance and stability within the body (example is maintaining body temperature).
homeostasis
Where is DNA located in the cell?
nucleus
term for building block (example: monosaccaride, fatty acid chains + glycerol, amino acids, nucleotide)
monomer or subunit
Plants (producers or autotrophs) do this to make their own food (glucose).
photosynthesis
What is the monomer or subunit of DNA and RNA?
nucleotide
Which 2 biomolecules provide energy?
Carbohydrates and Lipids
Plant and animal cells are both classified as this type of cell.
eukaryotic cell
A change in DNA that increases the variety of offspring in a species. Examples are substitution, deletion and insertion.
mutation
A sequence of who eats who to gain energy in an ecosystem.
food chain
Phase in the cell cycle where DNA is replicated and the cell prepares for division.
Interphase
What are the nitrogenous bases of DNA?
Adenine, thymine, guanine, cytosine
Monomer of a protein
amino acid
This is the 3 letter term for energy
ATP
This process results in 2 identical strands of DNA.
DNA Replication
Who did it?
Suspect 2
The organelle that produces proteins, site of protein synthesis
ribosomes
The remains of organisms preserved in rock or ice that can be evidence of evolution.
fossils
Evaporation - condensation - precipitation
the water cycle
What is the number of chromosomes in a human haploid and diploid cell? (2 answers)
23 and 46
What are the 3 types of RNA?
Messenger, transfer, and ribosomal
Always a protein, these act as a catalyst to speed up chemical reaction (hint: lock and key)
enzymes
What are the reactants of photosynthesis AND/OR the products of cellular respiration?
Sunlight (Energy), Water (H2O), and Carbon Dioxide (CO2)
DNA is transcribed to make this. This process happens in the nucleus.
Transcription?
What process is represented in the diagram below?
Mitosis
What is the site of cellular respiration and photosynthesis?
mitochondria and chloroplast
When an entire species dies out
extinction
A relationship among organisms where both benefit from each other
hint: (+,+) or two smiley faces
mutualism
A disruption in Mitosis would effect these types of cells.
body cells or somatic cells
Which chromosome are sex-linked traits located on?
the X chromosome
Glucose, Fructose, Lactose, Sucrose, -ose, -ose, -ose
What are these examples of?
examples of Carbohydrates
What are the products of photosynthesis AND/OR the reactants of cellular respiration?
Oxygen (O2) and Glucose (C6H12O6)
What is the monomer of proteins?
amino acids
Below is a prokaryotic cell. We know it is a prokaryotic cell because it is missing which organelle?
nucleus
Which 2 organelles are only found in a plant cell?
Cell wall and Chloroplasts.
The concept that individuals who are best suited for their environment will live longer and reproduce more than those who are not
survival of the fittest or natural selection
What is the primary source of energy for all food webs?
the sun
The propose of this process (which happens in Meiosis) is to exchange DNA which causes genetic variation.
crossing over
This results in a phenotype in which the expressed physical trait is a combination or BLEND of the phenotypes of both alleles.
(Example: Red + White= Pink)
incomplete dominance
This element is found in all organic material.
carbon
Which organelle is responsible for making glucose in a plant cell?
chloroplast
Transcription of this DNA Sequence:
TACCGCTCC
AUGGCGAGG
________ proposed the theory of natural selection, however, his theory was lacking the genetic component. _________ (the father of genetics) helped to fill in the blanks.
Charles Darwin, Gregor Mendel
