Question 21: The correct answers are For a potential prey cell, being large makes it easier to avoid being eaten, For a predatory cell, being large makes it easier to eat other cells, and Larger cells possess a higher metabolic capacity.
Explanation: There are several advantages of larger cell size. The larger size enables the cells to be more complex and therefore these cells possess a higher metabolic capacity. The larger size also saves the prey cells from being eaten and at the same time the larger size helps the predator cell in making it easier to eat other cells.
Question 22: The correct answers are gymnosperms and angiosperms.
Explanation: The plants reproduce using seeds are called seed plants (Spermatophytes). Gymnosperms (flowerless plants) and angiosperms (flowering plants) are both seed plants.
Bryophytes and Ferns- both reproduce using spores.

Question 32 2 pts Which of the following is true of seedless vascular plants? They produce many spores, which are really the same as seeds. Sphagnum is an economically and ecologically important example, The gametophyte is the dominant generation Whole forests were dominated by large, seedless vascular plants during the Carboniferous period. O Extant seedless vascular plants are larger than the extinct varieties. If humans had been present to build log structures during the Carboniferous period (they weren't), which plant...

Question 1 1 pts Which of the following is true? Viruses cannot evolve because they are not technically alive; they cannot replicate on their own When viruses hijack a host's cells to replicate, mistakes made in the copying of their DNA or RNA can generate a huge number of genetic variants in the virus population A mutation in the molecules involved in binding to a host cell that allows binding to a new host species will not affect the virus's...
