Answer:
The correct answer is - O and 6.9; 7.1 and 14
Explanation:
A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.
It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.
Answer:
B) realized niche
Explanation:
The ecological niche refers to all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The term ecological niche refers to the fundamental niche or the realized niche.
- The fundamental niche refers<u> only</u> to factors or physical conditions under which a species can live and survive in the <u>absence of any interaction with other species.
</u>
- The realized niche refers to the restricted conditions in which a species can live and survive as a result of <u>environmental conditions and the interaction with other species</u><u>.
</u>
When an inferior competitor is excluded by the superior competitor, this is known as competitive exclusion. This occurs when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective or realized niche of the dominant species completely occupies the fundamental niche of the inferior competitor.
In the exposed example the organism is able to occupy a niche in the presence of competitors, which is the clue for us to classify this niche as a realized niche. The organism needs to interact in a certain way with its competitors. There is an interaction between taxonomic groups, or between individuals.
Answer:
Edwin Hubble's findings supporting the 'big bang theory' are as follows – almost all galaxies are moving away from us and the 'farther away a galaxy' is, the faster it is moving away.
Explanation:
The theory speaks of an ever-expanding universe and the proponent calculated the Law of Hubble.
The answer is D because the volcano cause that to happen
