The table below lists human blood group genotypes and phenotypes.

Why is the AB phenotype a result of codominance?

• Neither allele is expressed in the phenotype.

• Both alleles are equally expressed in the phenotype.

• One allele masks the expression of the other during expression of the phenotype.

• Both alleles blend together to form an intermediate phenotype during expression.

SC.912.L.14.2 Which cell structure is correctly paired with its primary function?

• ribosome - protein synthesis

• vacuole - cell division

• nucleus - storage of nutrients

What are the two reactants of cellular respiration?

• C₆H₁₂O₆ & 6CO₂
• 6 CO₂ & 6H₂O
• C₆H₁₂O₆ & 6O₂

A tapeworm lives in the intestine of a cat absorbing nutrients through its skin. A tapeworm and a cat have this type of relationship.

• mutualism

• parasitism

• commensalism

• competition

The organelle that captures the energy from sunlight and converts it into chemical energy stored in food during photosynthesis:

• Chloroplast

• Mitochondrion

• Cell Wall

• Nucleus

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

What must occur during the cell cycle to ensure proper division of the chromosomes?  

• The cell must grow in size
• The mitochondria must divide 
• The DNA of the cell must replicate
• The cell membrane must dissolve

The stages of the cell cycle are shown in random order below.  Starting with prophase, sequence the diagrams to show the stages of mitosis.  
                       

• 5-3-1-2-4
• 3-1-4-2-5
• 4-1-2-5-3
• 2-3-1-5-4
