RANDOM!
What base pairs with A in RNA?
U
Happens in somatic (body) cells only.
mitosis
Aa
(having two DIFFERENT alleles)
Heterozygous
What is evolution?
change over time
Autotroph
What type of molecule gives you FAST energy and ends in "ose"?(carbs, lipids, or proteins)
carbs
Functions to produce gametes.
meiosis
Having two of the same alleles.
Homozygous
True or false: individual organisms can evolve during their lifetime.
false
Where is there more total energy - at the top of the food chain or at the bottom of the food chain?
bottom
What important molecule is ABSENT during fermentation?
oxygen
Responsible for growth and healing.
mitosis
Organism that CANNOT make its own food and CANNOT do photosynthesis
heterotroph
The physical traits of an organism.
phenotype
What is a major cause of global climate change?
greenhouse gases
What is the function of the ribosome?
make proteins
makes different cells
meiosis
Type of structure that is similar among organisms and indicates a common ancestor (like the hand bones of all mammals)
Homologous structures
Red and white are codominant in flowers.
If you cross a pure-breeding red flower with a pure-breeding white flower, this is what you can expect in the offspring. (DRAW A PUNNETT SQUARE!)
all red and white
Describe the carbon cycle.
(Name 1 thing that gives off carbon dioxide, and 1 thing that takes in carbon dioxide).
respiration, photosynthesis
Which organelle does photosynthesis, and which one does cellular respiration?
chloroplast, mitochondria
Crossing over takes place in this process to increase genetic diversity (when chromosomes share alleles)
meiosis
These types of cells - with only ONE copy of each chromosome - are made during meiosis.
Haploid
Black is dominant to brown in bears.
A brown bear mates with a heterozygous black bear. What percent of their offspring will also be black? (DRAW A PUNNETT SQUARE!)
50%
Two organisms are in a relationship that is mutualistic. Are they:
a) both helping each other?
b) one helping, one hurting?
c) bone hurting each other?
A
