Which of the following best explains why the biosphere is a key component of the earth’s systems.
a.

the biosphere is a key component of the earth’s systems because it is a common concept to many disciplines in science.

b.

the biosphere is a key component of the earth’s systems because the seasonal cycles directly affect primary productivity.

c.

the biosphere is a key component of the earth’s systems because it drive the other systems by interacting with and exchanging matter and energy with the other spheres.

d.

the biosphere is a key component of the earth’s systems because it has evolved to create the chemical composition of the planet we know today.

Answer;

The biosphere is a key component of the Earth’s systems because it helps drive the other systems by interacting with and exchanging matter and energy with the other spheres.  

Explanation;

-The biosphere contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth.

-Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Deserts, grasslands, and tropical rainforests are three of the many types of biomes that exist within the biosphere.

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

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
