Hypothesis that states that the continents were once one large mass that broke apart?

Answer:

Continental drift

Explanation:

Alfred Wagener told about continental drift. He said that continents were a single land mass called Pangaea. They were separated and relocated in the form of different continents. The drifting happens due to the movement of tectonic plates above the magma. As a result, the land mass was broken down into different landforms.  These broken parts were carried slowly and form the continents. The continents are now also moving slowly

The hypothesis which states that the continents were once a large mass that broke away into different parts is the continental drift or the plate tectonics.

Further Explanation:

The continental drift theory was developed by Alfred Wegener in 1912, who was a meteorologist and a geophysicist. He proposed that the Earth’s rotation lead to the shift of continents away from each other. According to him, all the continents were bound together into a supercontinent called Pangaea which means single mass of land. The Pangaea broke into different continents which eventually moved to their respective locations.

The reason for the occurrence of continental drift given by Alfred was discarded by other scientists. It was later discovered that the actual reason for continental drift to occur was the theory of plate tectonics which explains the separation of continents due to the movement of tectonic plates below the Earth’s surface.

The topmost mantle and the pieces of Earth’s crust are called tectonic plates which together forms the lithosphere. The theory which described the movement of small and large plates in large-scale under the lithosphere is termed as Plate tectonics. The convection in the mantle is the reason for the plate tectonics. The high temperature in the Earth’s interior leads to the movement of plates in the lithosphere. Due to this the flow of current in the hot rising magma and the cooler magma causes sinking. This resulted in pushing and spreading away of the plates. The gaps called the mid-ocean gaps present between the tectonic plates widened up followed by filling up by the hot magma. This leads to the formation of new ocean crust and separation of the plates.

Select all that apply. Choose the cells that are diploid. egg nerve bone sperm muscle
Natali5045456 [20]
The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.

Which part of the cell theory changed between 1838 and 1855?
mote1985 [20]

Answer:

Been brought about by the cell theory announced by Theodor Schwann and Matthias Schleiden in 1838, whereby cells were held to be the basic units of all living tissues. Improvements in the microscope during the 19th century made it possible gradually to lay bare the basic structures of cells.
