Mystery fossil genus A has been dated to the late Pliocene and early Pleistocene. It had two premolars in each mouth quadrant and bilphodont molars. Its canines were sexually dimorphic, and males had slightly larger and longer crania than females. Its postcranial traits indicate it was a terrestrial quadruped, and its overall body size was considerably larger than its living primate relatives. Mystery fossil genus B has been dated to the early Miocene. It had three premolars in each mouth quadrant and sexually dimorphic canines. Its teeth indicate a frugivorous diet. It had a medium body size similar to its living primate relatives. Required:
a. Which of these mystery fossils is a fossil Old World monkey?
b. Which of these mystery fossils is a fossil New World monkey?
c. Describe two traits you used to make these identifications. (Be sure to describe how each trait varied in the two mystery fossils.)

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
