Answer:
Hydras live in fresh water environments, while sea anemones live in MARINE environments! Hydra, although primarily sessile (sedentary), may move up to several inches in a day.
Answer:
A topographic map is a detailed and accurate representation.
Explanation:
A topographic map represent all made made and natural features on the earth's surface. This can be used for different purposes or activities like- hunting, fishing, hiking, surveying an area, urban planning and so on. A topographic map has a distinct feature that is three-dimensional shape is modeled by the contour lines. Topographic maps are produced by NTS- Canadian National Topographic System. Topographic maps can describe the vertical information through the use of contour lines.
Answer:
D) movement of the tectonic plates.
Explanation:
Lets understand first what convection is. It refers to the process through which denser material sinks and less dense material rises. This is because less dense material is more buoyant than denser one.
The earth is composed of water, rocks and air and all these things lower their density when there occurs an increase in their temperature.
So what happens when convection occurs in the upper mantle of earth, it raises the less dense material called magma in uprising direction, because of the extreme heat in the Earth’s core. When molten lava moves upwards it moves in a fashion of convection, but then it cools down and sinks again.
As the earth surface is made up of tectonic plates. Scientists believe that when convection occur in mantle layer, it causes the movement of plates, This movement can be away from, or towards each other. The movement of tectonic plates causes shifts continents, ocean basins, earthquakes and pushes up mountains.
So D is best option.
Hope it helps!
An earthquake is the result of a sudden release of stored energy in the earths crust that creates seismic waves.
The statement 'identical to the parent' will be added to the venn diagram for asexual reproduction. This is because, sexual reproduction always give rise to offspring that are different from their parents while asexual reproduction give rise to offspring that are identical to their parents.
