The correct answer is option B, that is, all living organisms are composed of one or more cells, which came from pre-existing cells.

A scientific theory refers to a well-substantiated illustration of some characteristic of the natural world, on the basis of a number of facts, which have been repeatedly confirmed via the experiment and observation. Such fact-supported theories are not hypotheses, however, are reliable explanations of the real world.

Andrej [43]

Answer:

a. biomes

Explanation:

Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.

An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

Generally, the different continents on Earth are in a constant motion due to the fact that they're sitted on top of gigantic plates floating on Earth’s mantle.

Furthermore, the Earth’s core generate energy which also creates convection currents in the molten layer of the Earth, thereby, moving the plates.

Over an extremely long periods of time, the movement of these plates create new biomes.

In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.

There are five (5) main types of biomes and these are;

I. Forest.

II. Aquatic.

III. Desert.

IV. Grassland.

V. Tundra.
