- Q1Stargardt’s disease, a genetic disorder that causes vision loss, is being treated using retinal cells derived from human embryonic stem cells. Why are embryonic stem cells used?They are able to differentiate into the required cell type.There are no ethical issues concerning their use.They are already specialized for this function.They retain stem cell properties after specialization.30s
- Q2Which method provides biochemical evidence that cells have begun to differentiate?Analysis of the proteinsObservation with an electron microscopeExamination of the DNA sequenceObservation with a light microscope30s
- Q3What feature of both striated muscle and aseptate fungal hyphae is different from typical cell structure?They have plasmids.They have an absence of cholesterol in the plasma membrane.They have a cell wall that is not made of cellulose.They have multiple nuclei within a structural unit.30s
- Q4When compared to other body cells, which characteristic of stem cells is the most important for therapeutic uses?Less excretionLower rate of reproductionLess differentiationLower rate of metabolism30s
- Q5Pasteur carried out a series of experiments that provided strong evidence against a widely supported theory. What was this theory?EvolutionSpontaneous generationEndosymbiosisConservative replication of DNA30s
- Q6Which functions of life are carried out by all unicellular organisms?Reproduction, ventilation, response and nutritionResponse, homeostasis, metabolism and growthResponse, homeostasis, metabolism and growthResponse, homeostasis, growth and photosynthesis30s
- Q7Why do multicellular organisms have emergent properties?They show properties that can only result from the interaction of many cells.All of their genes are expressed whereas unicellular organisms express only some.Properties of unicellular organisms are enhanced by having many cells.They have more genes than unicellular organisms.30s
- Q8What happens to the cell surface area to volume ratio as a cell grows?It increases, so osmosis is reduced.It increases, so mineral ion absorption is increased.It decreases, so rate of gas exchange is too low.It decreases, so production of waste material is reduced.30s
- Q9Which sequence shows increasing relative size?CDBA30s
- Q10In a copy of Louis Pasteur’s famous experiment, broth was put into flasks as shown in the diagrams. What results would be expected with no spontaneous generation of life?Decomposition of broth by microbes occurred only in Flasks W and X.Decomposition of broth by microbes occurred only in Flask W.Decomposition of broth by microbes occurred only in Flasks W, X and Z.Decomposition of broth by microbes occurred only in Flasks W, X and Y.30s
- Q11What can be deduced about a striated muscle fibre from both of these statements?"A eukaryotic cell has one nucleus." "A striated muscle fiber has many nuclei."It is preparing to divide.It is prokaryotic.It consists of aseptate hyphae.It is an exception to cell theory.30s
- Q12Which graph represents the change in cell surface area to volume ratio with increasing cell diameter?BADC30s
- Q13The statement relates to Pasteur’s experiments. What did this statement suggest?Nutrients are a requirement for mold growth.Mold evolved by endosymbiosis.Cells can only be formed by division of pre-existing cellsOxygen is required for anaerobic respiration.30s
