HELP PLEASE Extend your thinking: Many chemical properties are determined by the number of valence

electrons. Elements with the same number of valence electrons will have similar properties.

Which element has similar properties to lithium? Beryllium?

Explain:

Substances effect: partially blocks (h+)/pyruvate symporter, interfering with the transport of pyruvate into the mitochondria. will this make the body lose or gain weight?

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species

Agenus is a taxonomic grouping that identifies a collection of species. when a scientist discovers a new species, how is this species assigned to a genus
