Eukaryotic organisms have membrane-bound organelles. Which of these organelles is considered the "control center" and stores the genetic material for the cell?
The nucleus.
100
This is the type of
cell division in which parent cells
produce daughter cells with the same
number of chromosomes as the parent
cells.
What is Mitosis?
100
This macromolecule is made of monosaccharide subunits and is a good source of energy
What is a carbohydrate?
100
A scientist treats a cell with a chemical that destroys the ribosomes. As a result, this will not occur.
What is Protein Synthesis?
100
The crab Lybia tessellata carries a pair
of sea anemones on its claws. The
crab uses the sea anemone’s stinging
tentacles as protection and the sea
anemone obtains small food particles
released by the crab as it feeds. Which type of symbiotic relationship does this best illustrate?
What is mutualism?
200
Placing wilted lettuce in cold water
will make it crisp again. This is the name of the process that causes the lettuce to become crisp again.
What is osmosis?
200
This process occurs in the nucleus and produces a molecule of mRNA
What is Transcription?
200
This special protein speeds up chemical reactions in the body.
What is an enzyme?
200
The by-product of this energy-storing reaction is oxygen.
What is photosynthesis?
200
In an ecosystem, this is likely to happen to the population of producers if the population of herbivores disappears.
What is overpopulation (or an increase in population)?
300
This organelle is the site of aerobic cellular respiration in eukaryotic cells.
What is Mitochondrion
300
Hitchhiker’s thumb (H) is dominant to no hitchhiker’s thumb (h). A woman who does not have hitchhiker’s thumb marries a man who is heterozygous for hitchhiker’s thumb. What is the probable genotypic ratio of their children? (make a punnet square)
What is 50% Hh and 50% hh?
300
This type of bond is created when atoms share a pair of electrons.
What is a covalent bond?
300
In humans, glucose is kept in balance in the bloodstream by insulin. Which characteristic of life does this best illustrate?
What is Homeostasis?
300
This is the correct order of the following terms from smallest to broadest: ecosystem, organism, population, community
What is organism, population, community, ecosystem?
400
A sugar, a phosphate group, and a nitrogen base form a nucleotide which is the building block (monomer) of which organic compound?
What is Nucleic Acid
400
Some flowers show incomplete dominance. If WW = white and RR = red, which phenotypic ratio would be expected in the offspring of two pink flowers?
1 Red(25%): 2 Pink(50%): 1 White (25%)
400
This type of bond forms between the hydrogen atoms and oxygen atoms of separate water molecules.
What is a hydrogen bond?
400
Cells can use this process to make a small amount of ATP even if no oxygen is available.
What is fermentation?
400
This will most likely happen to the amount of carbon dioxide in the atmosphere if the producers are removed from the carbon cycle.
What is it will increase?
500
If a daughter cell does not have enough DNA after mitosis because the DNA of the parent cell was not replicated, there was likely an error in this phase of the cell cycle.
What is the S-phase?
500
This is the location of protein synthesis (also known as translation)
What is the ribosome?
500
This type of macromolecule can store energy, but also makes up the majority of the cell membrane.
What is a lipid?
500
What is the function of enzymes in
biological systems?
To speed up chemical reactions
500
This is the percentage of available energy from one trophic level that is passed on to the next level.
