The "Process of Science"
This part of an experiment is what the researcher changes intentionally. It is the part that is being tested.
independent variable
The concentration of glucose inside the blood must be maintained within a fairly narrow range in most vertebrates. This statement is an example of this.
homeostasis
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
how much energy transfers from one trophic level to another ?
10%
What should be done to ensure the results are "valid" or conclusive in/after an experiment?
Repeated Trials (or scientific review)
This biomolecule is a prominent part of animals which functions in insulation, helping animals conserve heat, and long term energy storage
lipid
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 theory suggests that organisms with the best adaptations are able to survive and reproduce, passing on their beneficial traits to the next generation.
natural selection
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
This type of bond is made when atoms share electrons
covalent bond
This organelle uses oxygen and glucose to produce carbon dioxide, water, and ATP
mitochondria
This molecule is responsible for carrying DNA's message from the nucleus to the ribosome.
mRNA (or messenger RNA)
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
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
These protein substances speed up chemical reactions.
enzymes
Plant, Bacteria and fungi cells ALL contain this organelle, while animal cells do not.
a cell wall
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
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
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
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
Name one of the two organelles used for cellular movement
flagella or cillia
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 the puppies ?
phenotype - gray
genotype CBCW
list 3 pieces of evidence which can be used to support evolution
dna, fossils, vestigial structures, embryology, homologous structures
