Facilitates the roots of plants going down towards gravity and the stems to rise up away from gravity. ... Thus, the difference is that geotropism is driven by gravity and phototropism is driven by light.
Answer:
Shape of Red Blood Cells Erythrocytes are biconcave discs with very shallow centers. This shape optimizes the ratio of surface area to volume, facilitating gas exchange. It also enables them to fold up as they move through narrow blood vessels.
Answer:
<em>The correct option is D) Diane will have to travel a farther distance to move the chair.</em>
Explanation:
To slide the chair up an inclined path, Diana would have to travel a further distance. While using the ladder to reach the second floor window would have made the distance smaller, but more force would have been required to move the chair through climbing a ladder. Diane would have got easily exhausted for moving the chair across the ladder. Using the inclined path will make the distance farther but as much force would not be required in this process. Hence, the method of using an incline is better.
Answer:
-1.Cold air sinks,has high density,and creates areas of low pressure.
-2.Warm air rises,has low density,and creates areas of high pressure.
-3.Wind is the movement of air from an area of high pressure to an area of low pressure.
-4. The angle of the earth affects the amount of energy an area receives
-5.More sunlight reaches the Earth at the equator
-6.Topics(near the equator) have warm air that rises,creating areas of high pressure.
-7.North and South poles have low air that sinks,creating areas of high pressure.

Answer: Option A.
Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.
