Ecology
The maximum amount of organisms an environment can support indefinitely.
What is a carrying capacity of an ecosystem?
The main function of this type of organelle is to create energy and complete cell respiration.
What is the main function of the mitochondira?
This is a 7 for water, and anything above is considered basic. Anything below is considered as acidic.
What is a pH?
These are the haploid cells used during the process of meiosis.
What are gametes?
What genes mask recessive genes?
Dominant
Only 10% of energy is passed down between trophic levels, because most energy is lost as heat energy.
What is the rule of 10's?
The diffusion of water across a cell membrane~ water moves high to low.
What is osmosis?
This was first used to treat CF and SCIDS.
What is Gene therapy?
True or false: Chromosomes can be seen during the prophase of a cell.
False
A cross done to determine the genotype of an individual with a dominant phenotype.
What is a testcross?
These are populations in countries that aren't reproducing faster than they are dying, so their population is shrinking.
What is a "graying population?"
6CO2 + 6H2O + Light --> 6O2 + C6H12O6
What is the formula for photosynthesis?
These are the organic compounds in living things.
What are carbohydrates, lipids, nucleic acids, and proteins?
What is crossing over and when does it occur?
This is when neither allele is dominant enough to take over fully, so they both show and blend together.
What is incomplete dominance?
Also known as chlorofluorocarbon, these aerosol chemicals are the reason for the thinning of the ozone layer and were banned in 2010 due to the harming of our atmosphere.
What are CFCs?
6O2+ C6H12O6 --> 6CO2 + 6H2O+ ATP
What is the formula for cellular respiration?
A laboratory method that cuts DNA and separates it by size to create a DNA fingerprint.
What is gel electrophoresis?
The G1 phase, S phase, and G2 phase make this up. This is where DNA is replicated in a cell.
What is interphase?
In tomatoes, red fruit (R) is dominant over yellow fruit (r). A plant that is homozygous for red fruit is crossed with a plant that has yellow fruit. What percentage of the next generation would be homozygous recessive?
0%
A food chain goes as follows: kelp -> sea urchin -> sea otter -> bald eagle. Let's say the sea otters begin to die off due to some unknown disease. Which organism is harmed the most by the decrease of sea otters?
The bald eagles. (their food source is being dwindled down~ they can't get their energy somewhere else.)
Allows for gas exchange to occur in a plant, mostly allowing carbon dioxide to enter the plant.
What is the function of the stomata?
The steps to this process are: 1. remove a gene and plasmid from a human and bacteria. 2. using an enzyme, cleave plasmid once and gene twice. 3. Fragments are spliced (combined). 4. Insert the new DNA back into the bacteria. 5. Let the cell replicate.
How do you genetically engineer DNA?
What are some of the biggest differences of meiosis and mitosis? List 3.
POSSIBLE RESPONSES: Mitosis makes 2 cells and meiosis makes 4, mitosis cells are identical and meiosis cells not, mitosis cells stay diploid while meiosis cells are haploid, and mitosis is to grow and replace while meiosis is to reproduce.
Coat colors in mice can be yellow, white, or cream. Yellow and white colored mice are homozygous and cream is heterozygous. Cross two cream colored mice, then provide the ratio of phenotypes.
White= 1/4
Cream= 2/4
Yellow= 1/4
