Kaylis [27]
As glaciers melted at the end of the last Ice Age worldwide sea level increased immensely and river plains were flooded. Glaciers are floating bodies of ice. Ice is frozen water. When glaciers started melting water that had been frozen for decades or centuries was released back into the ocean. That lead to an increase in sea level. This also led to river plains being drowned/flooded. Therefore, the answer is 1 and 2.

hram777 [196]

Answer:

Inversely

Explanation:

pV = k

When p increases, V must decrease for k to remain constant.

When V increases, p must decrease for k to remain constant.

When the product of two variables is a constant, they are inversely proportional  to each other.

Choose one scientist who made a note-worthy contribution to our current understanding of cells and explain what the contribution
alina1380 [7]

Answer:

See the answer below

Explanation:

There are several scientists that contributed to the understanding of the cell. Some of them and their contributions are as follows:

Anton van Leeuwenhoek: He invented the first primitive microscope and was able to view some unicellular microscopic cells such as protozoans and bacteria. He disproved the theory of spontaneous generation by his discoveries.

Robert Hooke (1665): He improved further on the microscope invented by Leeuwenhoek and was able to view compartment-like rooms when tissues of cork were sectioned. He tagged the compartment as 'cell'.

Schleiden (1804–1881): Using an improved microscope, he was able to extensively study plant tissues and borrowed the word coined by Hooke (cell) to describe the component of the plant tissues.

Theodor Schwann (1810–1882): He studied animal tissues and made a similar observation as Schleiden.

Through their various studies, Schleiden, Schwann, and another scientist, Rudolf Virchow later developed what is nowadays known as the cell theory
