The "Process of Science"
Question: How does sunlight exposure impact healing rate for a wound.
What would the IV & DV be?
IV: Amount of Sunlight Exposure
DV: Healing Rate of Wound
how much energy transfers from one trophic level to another ?
10%
A cell with numerous ribosomes is probably specialized for this task.
making proteins
One side of a DNA molecules reads TCA GTC, the other side would read
AGT CAG
This type of bond is made when atoms share electrons
covalent bond
The concentration of glucose inside the blood must be maintained within a fairly narrow range in most vertebrates to keep the internal balance. This statement is an example of this.
homeostasis
This type of succession occurs when a volcano erupts and soil has to be formed before organisms can begin to recolonize the area.
primary succession
These types of cells do NOT have a nucleus or other membrane-bound organelles.
prokaryotic cells
The division of gametes. This process involves the cell splitting twice, resulting in 4 genetically different haploid (n) cells
Meiosis
This is a term used when a cell gets too old/damaged and starts releasing chemicals to destroy itself
Apoptosis
A scientist designed an experiment to test the effect of temperature on bacterial growth. He grew three different cultures of the bacterium E. coli under three heat lamps at different temperatures - 110 degrees, 120 degrees, and 150 degrees. What is missing from this experiment ?
a control group
Phoresy is a phenomenon where one organism uses another organism for transportation. For instance, mites ride on the backs of beetles, which are unaffected by the presence of the mites. This type of symbiotic relationship can be as this.
commensalism
Some carrot sticks are placed in a strong salt water solution - what type of solution and what will happen to the carrot cells?
Hypertonic. The cells will shrink
This molecule is responsible for carrying DNA's message from the nucleus to the ribosome.
mRNA (or messenger RNA)
The complete equation for cellular respiration
6 O2 + C6H12O6 ==> 6 CO2 + 6 H2O + 36 ATP
These protein substances speed up chemical reactions.
enzymes
List 3 pieces of evidence which can be used to support evolution
dna, fossils, vestigial structures, embryology, homologous structures
List the 3 types of passive transport
Simple diffusion, facilitated diffusion, and osmosis
In pea plants, tall (T) is dominant to short (t). If two heterozygous plants are crossed, the possible offspring will have these GENOTYPE(S).
TT, Tt, and tt
List the 4 macromolecules and their monomers
Carbohydrate - monosaccharide
Lipid - fatty acid
Protein - amino acid
Nucleic Acid - nucleotide
List 4 of the 7 characteristics of life
made of cells, maintains homeostasis, responds to environment, grows, ability to reproduce, has RNA/DNA, has a metabolism
List the 8 taxa in order
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
Cells communicate by...
sending and receiving signals through receptors/bloodstream
In some dogs, coat color (C) shows incomplete dominance. A black dog and a white dog have puppies. What will be the genotype and phenotype of the puppies?
phenotype - gray
genotype - Cc
The two ways viruses use to reproduce
Lytic & Lysogenic
