3.04 Comparing Organell Complete the table below. Decide which institution you will use to compare the cell
organelles. You may choose a school building, a factory, or a city.
• For example, if you choose a school, then the nucleus of a school would be the
principal and the justification would be because the principal is in control and
command of the daily operation just like the nucleus is in control of the operation of
the cell.
• If you choose a city, then the electrical power plant would be the mitochondria and
the justification would be because the power plant is responsible for providing energy
to all parts of the city just like a power plant provides energy to all parts of the cell.
Remember if you choose an animal cell, then there are 3 of the organelles that you should
not include because they only occur in plants.

answer; ///(b) it is composed of four protein chains and four heme groups;

the answer is b.) hydrogen bonds between bases.

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.
