Creates ATP
Photosynthesis releases oxygen into air
Removes water from the soil
Creates glucose that animals use for food
What makes cancer cells different from healthy, normal cells?
Cancer cells divide uncontrollably.
Label the DNA molecule
Active transport (a) energy while passive transport (b) energy. Active transport moves molecules (c) the concentration gradient and passive transport moves molecules (d) the gradient.
Genes that are activated will (a) DNA to mRNA and (b) mRNA to proteins.
Crossing over results in- (select all)
increased genetic variation
Less chromosomes
New combinations of alleles
Two identical daughter cells
Type the complementary DNA strand to the one shown-
GTC TTC TTT TAA
(a)
An individual develops skin cancer, affecting their somatic cells. What percent of their offspring are expected to inherit the cancer?
(a)
A dad with the genotype AA and a mom with the genotype aa will produce offpspring with the genotype-

Artic Foxes have two different fur colors; they are brown in the summer and white in the winter. This is due to the amount of light available each season. This environmental factor is affecting-
Cellular Respiration
Photosynthesis
Gene Expression
DNA Replication
Original mRNA: AUC GCG UUG UAC ACG
Mutated mRNA: AUC GCG UUG UAG ACG
What type of effect will this mutation have?
Frameshift mutation- Changes reading frame
Missense mutation- One amino acid changes
Nonsense mutation- Early stop
Silent mutation- No effect on amino acids
What are the functions of each biomolecule?
Short term energy
long term energy
structure and support
Chemical messengers
energy
helps with cell transport
Select the two parts that make up the back bone of DNA.
Cats have 38 chromosomes in their somatic cells. How many chromosomes will cells produced in meiosis contain in cats?
(a)
Match the following
Trait that requires 2 alleles to show
Recessive
Trait that only requires 1 allele to show
Dominant
Homozygous
2 of the same alleles
Heterozygous
2 different alleles
Match the following mutation effects
Silent mutation
Does not affect the amino acid sequence
Frameshift mutation
Shifts the reading frame of the genetic message
Missense mutation
Changes one amino acid
Nonsense mutation
Results in early stop codon
Maintaining equilibrium between an external and internal environment
Mr. Brown and his 5 enzyme copies walk around the room slapping students. 3 of the enzymes get too hot and have to leave the room. What will be the effect?
Less students will be slapped
The amount of energy needed to slap students goes down
More students will be slapped
The amount of students increases
Albinism is a recessive trait that causes lightened skin, hair and eyes. Two heterozygous parents are crossed. What is the expected percentage of their offspring that will be albino (have albinism)?
(a)
