Asnapdragon is a type of flowering plant. in snapdragons, the allele for red flowers (r) is incompletely dominant over the allele for white flowers (r). part a: predict the phenotype that will be expressed by a snapdragon that is heterozygous for flower color (rr). part b: suppose two snapdragons that are heterozygous for flower color (rr) are crossed. predict the percentage of each possible phenotype that will result from this cross. in your answer, be sure to explain the reasoning behind your prediction. part c: a gardener wants to produce a generation of snapdragons that displays only the phenotype associated with the heterozygous genotype (rr). determine the genotypes and phenotypes of the snapdragons the gardener should cross to accomplish this goal. in your answer, be sure to explain the reasoning behind your decision. type your responses to parts a, b, and c in the box below.

Which of these is true for bacteria because they are prokaryotic cells? a. they can engulf body cells in order to make memory cells. b. they must invade viruses in order to reproduce. c. they are much larger than eukaryotic body cells. d. they can reproduce on their own outside of other cells.

Astudent from one of the research labs is having trouble preparing a slide for examination and photographing. the bacterial slide that he has brought to you was prepared using a commercially purchased stain. he has asked for your in determining what he is doing wrong so that he can change the lab protocols and continue on with his project. after examining the slide under oil immersion, you determine that no bacteria are present even though the student is able to show you the culture he used to make that slide that has visible growth in the liquid medium. which of the following statements does not explain the fact that there are no bacteria present on the student’s slide? by not allowing a glass slide to completely air dry before heat fixation, the flame will cause the surrounding water to boil and this will damage the bacterial cell. overheating during the fixation step boiled the water within the bacterial cells and resulted in the cells bursting. insufficient heating of the slide did not drive out the thin layer of water and this resulted in minimal bonding between the bacteria and the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide.
