What might the student look for under a microscope are plant cells or animal cells?

1 answer:

5 0

To find out if the cell is a plant cell, the student should look for a square shape in each cell. The cells are put together with their square like shape so it may look like a brick wall depending on the cell.

To find out if the cell is an animal cell, the student should look for more rounded shapes. Usually, animal cells are rounded unlike the plant cell because they do not have a cell wall.

What type of volcano forms as lava spreads over a long distance, and then cools and forms a hill that slopes gently? fissure com

storchak [24]

Answer:

The correct answer is ''shield volcano.''

Explanation:

Shield volcanoes are those whose diameter is much greater than its height. They are formed by the successive accumulation of very fluid lava flows. So they are of considerable height and slight slope. Its topography is smooth and its top forms a poorly defined depression. Lava ejected during an eruption is largely basaltic in composition and has a very low viscosity (it is liquid). Because of this, lava flows easily and spreads over a large area. Shield volcano eruptions generally involve lava that travels great distances and spreads out in thin layers. As a result, the volcanic mountain that is built over time by repeated lava flows has a broad, smooth profile leading away from a bowl-shaped depression at the top known as a caldera.
