All living things need energy; it is a requirement for life. in a typical cell, atp, the high energy molecule, is produced in the in the presence of a sugar (glucose) and a) nucleus; oxygen b) er; carbon dioxide. c) mitochondria; oxygen. d) vacuole; water vapor.

The answer is C) mitochondria; oxygen

Adenosine triphosphate (ATP) is the main molecule for storing and transferring energy in cells. It is also called the energy currency of the cell.  ATP molecule composed of three phosphate groups. These phosphate groups are linked to one another by two high-energy phosphoanhydride bonds. ATP is produced in the mitochondria of all the living cell in the process of cellular respiration. During cellular sugar is oxidized in presence of oxygen to produce ATP.  

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
