What percentage of the offspring will exhibit red, long-stemmed flowers? 25 percent 50 percent 75 percent 100 percent

100 percent

A cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. Purple offspring result due to incomplete dominance.

Parents with the genotypes AO and AB have a child. What are all the possible blood types of the child? A, B O, AB A, AB, B O, AB, A

A, AB, B

Which blood type could be given as a transfusion for patient with AB blood when the RH factor is unknown? O+ A+ AB+ AB-

AB-

Chloroplasts have a complex internal structure, as shown in the model below. mc004-1.jpg In which location is glucose formed? Location A Location B Location C Location D

If Mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible? F1 generation only P generation only F1 generation and F2 generation P generation and F2 generation

P generation and F2 generation

Mendel was able to study seven traits in all the pea plants in each generation. Which of his hypotheses allowed him to analyze each trait separately? If two different alleles for a gene occur together, one of the alleles may be expressed while the other is hidden. When gametes are formed, each gamete carries only one allele for the gene. There are alternate versions of a alleles called genes. For each inherited trait, there is only one copy of the gene that codes for that trait.

When gametes are formed, each gamete carries only one allele for the gene.

Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous and has green-colored pods? Yy ´ yy YY ´ yy Yy ´ Yy yy ´ yy

Yy ´ yy

A dietician examines the diet of a patient who is complaining that he is unable to build muscle mass. The patient eats mainly fresh fruits, vegetables, pasta, bread, and some fats and oils. Which type of supplement will the dietician most likely recommend? citric acid fatty acids nucleic acids amino acids

amino acids

Smooth muscle, which is a tissue made up of a type of specialized muscle cell, functions in which process? food digestion skeletal movement pumping of blood heart contraction

food digestion

The equations summarize the process of fertilization. Which equation represents fertilization? haploid + diploid = diploid diploid + haploid = haploid haploid + haploid = diploid diploid + diploid = diploid

haploid + haploid = diploid

Some flowering plants appear to have offspring that have traits that are intermediate between those of the parents. Which type of dominance is exhibited by the offspring? complete dominance blended dominance codominance incomplete dominance

incomplete dominance

Which structure will form when a primitive cell engulfs an aerobic bacterium? mitochondria chloroplast nucleus cell membrane

mitochondria

What is the end result of the eukaryotic cell cycle? no parent cells and two daughter cells one parent cell and two daughter cells two parent cells and one daughter cell one parent cell and one daughter cell

no parent cells and two daughter cells

Which type of macromolecule is made up of subunits that are called amino acids? carbohydrate lipid nucleic acid protein

Which function of the cell cycle is especially important to burn victims? growth of existing cells repair of existing cells protection of new cells reproduction of new cells

reproduction of new cells

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is responsible for the change in the mRNA base? silent missense nonsense insertion

silent

Consider the diagram that depicts the lysogenic and lytic cycles. The steps of the lysogenic cycle are shown. In Step A, attachment and entry occurs. In step B, the provirus is formed. In step C, the cell begins to divide. In step D, the provirus leaves. In step E, the virus is replicated and assembled. In step F, lysis and release of the virus occurs. In which step of the diagram is the provirus formed? step A step B step E step F

step B

Missense, nonsense, and silent mutations are examples of which type of mutation? substitution insertion deletion replication

substitution
