Solar System Formation. Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.
Answer:
Temperatures gradient
Explanation:
There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.
Answer:
I would say B) Blow over water in a bowl to produce ripples.
The answer is; D
These cells are called plasmodesmata. They are significant in the symplastic flow (meaning through the cytoplasm) of water and other molecules in the plant. A membrane called desmotubule runs along the pores of adjacent plasmodesmata. These cells are also significant in the communication between cells.
