Julie has an ectomorph body type, which means she is tall and thin with long arms and legs
Which statement would least likely be used to describe variation? a) variations are inherited differences between individuals of the same species. b) variations that decrease reproductive success are more likely to be passed on. c) variations may result in changes to an entire population after many generations. d) variations provide some individuals with an advantage.
Which of the following mutations would most likely be identified as a chromosomal translocation? A sequence of bases encodes for genes XXY. A portion of another chromosome breaks off and inserts within genes XYZ. A mutation occurs while copying a chromosome. Instead of reading EFGHI, the chromosome reads EFGFGHI. The genetic sequence is MNOPQ. A mutation occurs and the sequence of bases that encodes for gene N is not copied. The sequence of bases on the mRNA reads CUU and codes for the amino acid Leucine. A mutation occurs and the mRNA sequence changes to CCU and now codes for the amino acid Proline.
Which fruit develops differently from the other two? . apple. bean. pineapple
Which one of the following statements holds true for the induced-fit model? a) once the enzyme binds to the specific substrate molecule , no structural changes can occur in the active site in the enzyme . b) once the enzyme binds to the specific substrate molecule , structural changes can occur in the active site to accommodate the product . c) once the enzyme binds to a specific substrate molecule , subtle structural changes can occur in the active site , which are reverted when the reaction is over
Which statement best compares the role of meiosis in a unicellular and a multicellular organisms? meiosis is the mechanism used for producing somatic cells in unicellular as well as multicellular organisms. meiosis is the mechanism used for producing gametes in unicellular organisms and somatic cells in multicellular organisms. meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does not play any role in unicellular organisms.
