Epimers are monosaccharide diastereoisomers that have a single asymmetric carbon. Anomers are diastereoisomers in which the hemiacetal carbon of a cyclic monosaccharide is asymmetric.
Determine whether each pair of monosaccharides consists of epimers, anomers, or an aldose‑ketose pair.

1) D-glucose and D-mannose
2) D-glucose and 1 fructose
3) D-galactose and D-glucose
4) D-glyceraldehyde and dihydroxyacetone
5) D-ribose and D-ribulose

Which of the following are causes of coastal erosion? check all that apply. beach grasses and other plants trap windblown sand. wave action carves away the coastline. groundwater under pressure is forced to earth’s surface. artificial structures stop the natural flow of sand along the coast. underground caves collapse as bedrock is dissolved.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
