Answer: Farmers use selective breeding for desirable traits. This is considered a type of genetic manipulation.
Explanation:
Answer : The molar concentration is, 
Explanation :
First we have to calculate the moles of protein.

Number of molecules of protein = 2 molecules
Avogadro's number = 

Now we have to calculate the radius.
Radius = 
Conversion used : (1 mm = 0.001 m)
Now we have to calculate the volume.



Conversion used : (1 m³ = 1000 L)
Now we have to calculate the molar concentration.



Thus, the molar concentration is, 
Answer:
It is the biological concept of species
Explanation:
In 1970 Mayr stated that "species are formed by groups of potentially intercrossing populations that are reproductively isolated from others". The biological concept of species puts emphasis on existence of barriers that limit the gene flow among groups within the same species
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
