A student grows two different varieties of soybeans in the same temperature and lighting conditions. At the same time each week, the student gives each plant an equal amount of water. The student measures the height of each soybean plant once per week. The graph shows the results of the experiment.
Answer: D) The plants grow at different rates because each soybean variety has a different set of genes.

In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.
Answer:The answer is C: How long does it take distilled water to evaporate from a 5” diameter container?
Explanation:
In the air, a salt solution will evaporate more slowly than pure water.
What is Evaporation?
The process by which a liquid transforms into a gas state is called evaporation. A surface phenomena, that is. The amount of evaporation depends on the humidity. If the air is humid, it is virtually saturated, which means that evaporation will occur at a much slower rate.
Since evaporation takes place on the liquid's surface, the salt molecules that are present on the water's surface prevent as much water from evaporating. As a result, salt water evaporates more slowly than pure water.
As a result, the salt solution will evaporate from the air more slowly than pure water.

Within earth’s crust, granite can become metamorphosed to form gneiss. Infer how this happens.
(write 1 paagraph)
Answer:
Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.

Do you think prevailing winds can affect climate zone distribution? Explain your reasoning with evidence
Answer:
Prevailing winds are the result of atmospheric circulation cells. They influence the climate of a region. Rising and sinking air can influence the precipitation of a region. Atmospheric circulation cells create the general climate of a region.
Explanation:
When Deshawn returned to his experiment, he observed these results. Six bottles labeled from 1 to 6 with their opening holes covered by balloons. Balloons on second and fourth bottles are inflated. Describe what you see in the results.
Answer: the second and fourth balloons have heat in them
Explanation:
Whenever there is heat in an object that hot gas rises and expands what ever is ontop of it like an air balloon.
Recent scientific studies have indicated that the amount of thermal energy stored in the oceans has increased rapidly since 1970. If the amount of thermal energy stored in the oceans continues to increase, how might this affect weather and climate?
Answer:
it would increase the water temperature and cause the sea levels to rise because of ice melting turning into more water.
Explanation:
it would increase the water temperature and cause the sea levels to rise because of ice melting turning into more water.
Increasing ocean heat is contributing to sea level rise, ocean heat waves and coral bleaching, and the melting of ocean-terminating glaciers and ice sheets around Greenland and Antarctica.
as global warming is increasing, the heat stored in oceans is increasing too fast. ocean currents act like a conveyer belt, by transporting warm water and precipitation from the equator toward the poles and cold water from the poles to the tropics. hence, the coastal climates are much more temperate because a water body i.e ocean is nearby to regulate the temperature.
as the heat capacity of the ocean is much greater than that of the atmosphere, the increase ultimately leads to a drastic rise in the overall weather of a region, directly affecting the climate cycle of the Earth.
