DNA is made up of (nucleotides / nitrogenous bases), joined by covalent bonds between the (adenine / guanine / thymine/ deoxyribose) of one monomer and the (phosphate group / nitrogenous base) of the next monomer. The DNA of all members of a species has (the same / a different) nitrogenous base composition. The percentage of (adenine (A) / guanine (G) / thymine (T) / cytosine (C)) always equals the percentage of thymine (T), and the percentage of (adenine (A) / guanine (G) / thymine (T) / cytosine (C)) equals the percentage of cytosine (C). It follows that if the percentage of adenine plus thymine equals 40%, then the percentage of guanine plus cytosine would equal (15% / 20% / 30% / 60%)​

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
