an advertisement on tv claims children grow faster with the use of vitamin gro. vitamin gro is a 25mg pill taken twice a day. th

e viewer has little knowledge about how children grow, but he knows that children need a complete diet and a good exercise routine. he decided to put the commercial to the test. the viewer uses his 6 nieces who are the same age to conduct the experiments. to make the experiment easier he uses his six nieces using labels such as child 1, child 2 and so on. he records their height every 3 days for 7 days. What are the variables?

Answer:

Independent variable - vitamin gro and exercise routine.

Dependent variable - growth of children or nieces.

Explanation:

There are two variables present in an experiment called dependent and independent variables.

Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.

In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.

Make a list of the things that make a hurricane different from a regular thunderstorm.
Katarina [22]

Answer:

The biggest difference is that hurricanes need a warm moist water to keep on going and never forms over land, while thunderstorms can form over land or water. Tornadoes are also associated with cumulonimbus clouds.

Explanation:

A hurricane is a swirling, low-pressure system that develops over the tropics with sustained winds that have reached at least 74 miles per hour.

Warm, moist air near the ocean's surface rises upward, cools, and condenses, forming clouds. With less air than before at the surface, the pressure drops there. Because air tends to move from high to low pressure, moist air from surrounding areas flows inward toward the low-pressure spot, creating winds. This air is warmed by the ocean's heat and the heat released from condensation, so it rises. This starts a process of warm air rising and forming clouds and surrounding air swirling in to take its place. Before long, you have a system of clouds and winds that begins to rotate as a result of the Coriolis effect, a type of force that causes rotational or cyclonic weather systems.

Hurricanes are the most dangerous when there is a big storm surge, which is a wave of seawater that floods communities. Some surges can reach depths of 20 feet and sweep away homes, cars, and even people.

A thunderstorm is produced by a cumulonimbus cloud, or thunderhead, that includes rain showers, lightning, and thunder.

They start when the sun heats the earth's surface and warms the layer of air above it. This warmed air rises and transfers heat to the upper levels of the atmosphere. As the air travels upward, it cools and the water vapor contained within it condenses to form liquid cloud droplets. As air continually travels aloft in this way, the cloud grows upward in the atmosphere, eventually reaching altitudes where the temperature is below freezing. Some of the cloud droplets freeze into ice particles, while others remain "supercooled." When these collide, they pick up electric charges from one another; when enough of those collisions happen, the big buildup of charge discharges, creating lightning.

Thunderstorms are most hazardous when rain decreases visibility, hail falls, lightning strikes or tornadoes develop.

Enzymes that breakdown disaccharides are located ________. a. in the lumen of the small intestine.
Dafna1 [17]
<span>Disaccharides need to be broken down into their component subunits (monosaccharides) before their absorption. The reaction that breaks them up is hydrolysis and it is done by enzymes- <span>glucosidases. Glucosidases are located on the brush border of the small intestine, attached to the surface of the epithelial cells. After the catalyzation of these disaccharides, the epithelial cells take up the monosaccharides and transport them inside using ATP energy. From there they are transported into the bloodstream.</span></span>

Scientists at the National Oceanic and Atmospheric Administration (NOAA) use mathematical computer-based models to help manage m
kobusy [5.1K]

Answer:

A). The model does not predict energy flow.

Explanation:

As per the given details, the most probable constraint of using 'numerical computer-built models' would be their 'inability to forecast the energy that is flowing throughout the ecosystem.' However, they assist in offering collected information at the same time yet <u>its failure to predict the actual amount of energy flowing that will lead to a failure to predict if the ecological balance is being maintained or not</u>. As a result, some organisms may be deprived of the appropriate food to ensure their survival and their existence on this planet might be under threat. Thus, this is the limitation of using such-technology based models and hence, <u>option A</u> is the correct answer.

What characteristic is shared by both inceptisols and entisols, the soils of flood plains?
marysya [2.9K]

<u>Answer</u>:

"Both are young and only beginning to develop horizons and a soil profile"is the characteristic  shared by both inceptisols and entisols, the soils of flood plains

<u>Explanation</u>:

Inceptisols and entisols are the soils that are seen in the floodplains. These soils are very weakly withered and also lacks organic matter. They are the sediments that comes from several other places through flood. The soil order of inceptisols in USDA in the soil taxonomy because they have the capability to form by the change of parent material. Also they are known to be more developed than that of entisols. Presence of clay, iron oxide, aluminium oxide and organic matters are also not found. But the entisols can not be changed from that of parent material. They are either rock or sediments.
