loeys-dietz syndrome (type 2b) is a human genetic disorder associated with mutations in the lds2b gene. researchers have proposed that the lds2b gene produces a growth factor receptor protein that regulates cell signaling pathways. the predicted product of the gene is 565-amino acid protein with structural regions that bind to signaling molecules, span the plasma membrane, and has protein kinase activity. protein kinases are cellular enzymes that transfer phosphate groups from atp to target proteins. calucate the minimum number of nucleotides required in the coding region of the lds2b mrna molecule to produce and terminate the 565-amino acid polypeptide. explain how you arrived at your answer

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

Which of the following would be an important part of a multi-step plan to restore the stability of the red-cockaded woodpecker's ecosystem?
