Question

Most animals exhibit the following structures or function except unique types of intercellular functions, such as tight function and gap functions. multicellularity. autotrophic nutrition sexual reproduction nervous and muscle issue. Which of the following is descriptive of protostomes? spiral and determine cleavage, blastopore becomes anus, enterocoeles development. spiral and determine cleavage, blastopore becomes mouth, ischiocele's development. spiral and determine cleavage, blastopore becomes mouth, ischiocele's development. spiral and determine cleavage, blastopore becomes anus, enterocoeles development. Transpiration in plants requires all of the following except active transport though xylem cells. cohesion between water molecules. adhesion of water molecules to cellulose. transport through tracheid's. evaporation of water molecules. Which of the following statements is correct about gram-negative bacteria? Their cell walls are primarily composed of peptidoglycan. Penicillin's are the belt antibiotics Co use against them. Then chromosomes are composed of DNA tightly wrapped around large amounts of histone proteins. On a cell-to-cell basis, they possess more DNA than do the edit of any taxonomically higher organism. They often possess an outer membrane containing toxic lipopolysaccharides. Which of the following statements is false about bulk flow? It is more effective than diffusion over distance grimier than 100 mu m. It depends on a difference in pressure potential at the source and sink. It is driven primarily by pressure potential. It may be the result of either positive or negative pressure potential. It depends on the force of gravity on a column of water. Seeds commonly provide for each of the following except a choice of germination location. desiccation resistance. dormancy. a nutrient supply for the embryo. dispersal.

Explanation / Answer

29 C autotrophic nutrition which means preparation of own food. Animals cannot prepare their own food

30. D protosomes undergo spiral cleavage which is determinate, blastopore develope to form mouth.

31. C. Transpiration means evaporation of water molecules in the form of water vapour from exposed parts of plants such as leaves. Adhesion of molecules with cellulose will decrease transpiration.

32. E

Gram negative bacteria has a complex lipopolysacchride layer whose lipid portion consists of endotoxin which if enters into human circulation can cause a toxic reaction
