Answer:
D: decomposers return carbon dioxide to the air
Explanation:
How does a new hypothesis replace an older explanation of something in the natural world? To understand this let us look at one of the classical example of geocentric theory and heliocentric theory. The geocentric theory states the Earth is at the centre of the solar system and the Sun, Moon, and all the other planets revolve around it. This ancient theory failed to explain the phenomenon like the phases of Moon, solar eclipse and lunar eclipse. The modern heliocentric theory which states that the Sun is at the centre of solar system, and all the planets including the Earth revolve around it. This theory was able to explain all the phenomenons unlike the geocentric theory. Hence the heliocentric theory replaced the geocentric theory.
Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
Petroleum is the primary fuel used for transportation in the US because it has a high energy value per unit volume and it has a quick start and stop times for providing energy. Additionally, petroleum is extremely easy to extract, it is a high density fuel, can also be transported over long distances and provides fuel that works with our infrastructure.
Answer:
VESICLES
Explanation:
Molecules of different types are produced in different compartments of a cell. These molecules, however, needs to be transported from one location to another. For this purpose, small spherical structures called VESICLES are used by the cell.
Vesicles are compartments in the cell that functions majorly as transport sacs. They help transport materials and molecules from one organnelle to another within a cell. For example, transport vesicles help in the transportation of matured proteins from the Golgi apparatus to respective locations in the cell.
