What did you include in your response? Check all that apply. All elements in group 13 have 3 valence electrons. Losing electrons during chemical reactions causes metallic behavior in elements. It is easier to lose 3 electrons than it is to gain 5, so most group 13 elements behave as metals. Having fewer electron shells makes it easier to gain electrons. Boron has so few electron shells that it is just as easy for it to lose electrons as it is to gain electrons, so it behaves like a metalloid.

Select all the correct answers. which statements fail to meet the requirements of a scientific claim? 1 even though evidence indicates that the solar system's planets follow elliptical paths, copernicus's model involving circular orbits is true. 2 the evidence supporting newton's laws of motion was accurate in newton's time, but the universe operates differently today. 3 flowers that reflect the most ultraviolet light are more likely to attract bees and other pollinators than flowers that reflect less ultraviolet light. 4 in the final 100 meters of a 10,000-meter race, an athlete's speed is more strongly related to anaerobic efficiency than to aerobic efficiency.

Sexual reproduction in the parent cell will result in offspring with a) identical genetic information. b) half the genetic information. c) double the genetic information. d) four times the genetic information.

Zoo geographic regions are characterized by the presence of specific groups of animals these regions are determined by the taxonomic or phylogenetic relationships of animals. the map shows the zoogeographic regions proposed by the naturalist alfred russel wallace in 1876. the similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between the organisms in both locations ?
