Acell biologist isolates a protein-rna complex that exhibits catalytic activity. treatment of this complex with rnase completely abolishes catalytic activity. however, treatment of the complex with proteases results in only a 15% decrease in catalytic activity. which of the following is the most likely explanation for these data?
a. the catalytic activity of the complex is enhanced by the protein component and completely dependent on the rna component of the complex.
b. the catalytic activity of the complex is independent of the protein component and only enhanced by the rna component of the complex.
c. the catalytic activity of the complex is completely dependent on the protein component and only enhanced by the rna component of the complex.
d. the catalytic activity of the complex is enhanced by the protein component and enhanced by the rna component of the complex.

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next
