Answer:
Option C = Ozone
Explanation:
The Percentage of given gases in atmosphere:
Oxygen = O₂ = 20.95 %
Nitrogen = N₂ = 78.08%
Argon = Ar = 0.93%
Ozone = O₃ = 0.000004%
Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.
Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.
The percentage of other gases in atmosphere are given below:
CO₂ = 0.0360%
Ne = 0.0018%
He = 0.0005%
CH₄ = 0.00017 %
N₂O = 0.0003%
H₂ = 0.00005%
Answer;
D. The immigration of the population is greater than the emigration.
Explanation;
A population consists of all the organisms of a given species that live in a particular area.
Populations change based on the births, deaths, immigrations, and emigrations that occur within the group. These additions and subtractions all affect population size, but do so in different ways.
Immigration is the migration of individuals into a population. Emigration, which is the migration of individuals out of a population, decreases the size of the given population.
Cell walls. This is a rigid layer made of cross-linked protein and sugars that surrounds the bacteria, holding it together and stopping it from exploding. The stain is called Gram's stain and is either purple (+ve) or pink (-ve). This distinction is used because it allows you to quickly cut the bacteria in half, and more importantly decide which antibiotic to give without actually having to grow the thing.
