Consider the four organisms you see here. Each represents a specific kingdom. They all exhibit the characteristics of life. Think about their life cycles. Compare and contrast the life cycles of the four. How do they differ?
A)
B)
Both the protist and the bacteria reproduce asexually. Their life span is
very short, less than a year, and they do not have stages of development,
Both the animal and the plant exhibit stages of growth during their
lifetimes. They have what might be described as a mature stage. The other
two, protist and bacteria do not.
Only two organisms reproduce sexually and have several life stages; the
plant and animal. The other two, the protist and bacteria, may have an
advantage because potentially can live forever.
The life spans of each kingdom vary greatly. The animal has the longest
life span and more stages of life during development than the others. The
bacteria, because it is the simplest, has the shortest life span

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.
