Explanation:
Looking at the Ecological concept of Modern Ecology
we have
Atmosphere, Lithosphere, Biosphere, Niche, Environment, Habitat, Population, Ecosystem and Biotic community
Hydrosphere and Geosphere are not part
so Atmosphere is the correct answer
Answer:
Tartar.
Explanation:
Dental plaque may be defined as the development of mass or biofilm of bacteria that grows on teeth surface. This plaque may present on teeth, between the teeth and on teeth front.
The plaque is first colorless but when it changes to dental calculus or tartar, the color of plaque becomes yellow or pale brown. This causes dental problem and different dental disease.
Thus, the answer is plaque.
different chemical reactions can occur in isolation of each other.
Further explanation
cells can be divided into 2 types according to the presence or absence of the cell nucleus membrane. Cells that do not have a nuclear membrane are called prokaryotic cells. Whereas cells that have cell nuclei are called eukaryotic cells. There are theories of biological evolution and the origin of life that explain the origins of prokaryotic and eukaryotic cell formation.
there is a theory that believes that eukaryotic cells are formed from the prokaryotic cell revolution which continues to grow increasingly complex.
actually the origin of life began in the ocean through the formation of organic compunds from simple compounds, then these compounds will continue to develop into more complex compounds. Simple complex compounds that will form a complex called primordial soup or primordial soup.
The formation of genetic material and cell membranes is believed to be two important steps after the formation of primordial soup and before life. The first genetic material and the first enzyme may be RNA.
Protobion develops into complex forms that contain DNA and can use many raw materials from the environment. Protobion will be replaced with organisms that can make the molecules they need (autotrophs).

Answer:
The correct answer is d Bill"s plasma contain B antibodies
Explanation:
As Bill"s plasma contain B antibodies that"s why his blood cells do not aggutinate when mixed with anti B serum.
I personally think that it's D. If this is right you're welcome. If it's wrong feel free to delete this answer :p
