The Correct Answer to the following question is <u>Mass</u>. Mass measures the amount of matter in a substance or an object.
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.
Answer:
Artery : carries blood away from the heart, largest blood vessel in diameter
Vein : carries blood to the heart, has a thin endothelial layer.
capillary : exchanges nutrients with tissues, single walled.
Explanation:
Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.
Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.
Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.
Answer:
3. liquid waste me directly into the ground water
Explanation:
Aquifer is a layer of water which is present inside the soil at a certain depth. There are certain areas where water is added to the aquifer and maintain the water level. These aquifers were polluted if liquid waste is dumped in these aquifer recharge areas and when this water is extracted through wells so health of both plants and animals are adversely affected. So for that reason liquid waste should not be dumped in recharge areas of aquifer.
