Equipment required: One or more buckets of water (or access to a garden hose connected to a water supply).
Pour one or two buckets of water (or run water from a garden hose) on bare ground (grass or soil is OK). Observe how the water moves. Some of the water may soak into the ground and some may flow over it. Pour a few more buckets (or run more water from the garden hose) over the same area and observe any differences in the behavior of the water. Does it still soak into the ground? Discuss how the moisture conditions in the soil will affect how much water gets absorbed. Would water be more likely to run off after the ground has been saturated by a heavy rainstorm? Discuss what happens to the water that gets absorbed into the ground.
Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city’s flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answer:
No water will be soaked by the soil if it has saturated condition.
Explanation:
If the soil does not reached to its saturated point so the soil will soak the water while on the other hand, if the soil reached to its saturated point so it will not absorb the water. If soil has more water so it will not be able to absorb more water. Yes, water will be more likely to run off after the ground has been saturated by a heavy rainstorm and the water absorbed by the soil remain in the soil for the plant while the large quantity of water percolates down and reach the water table. With no soil to absorb water, the water goes to rivers and streams when a heavy rainstorm held. The engineer has to built a well drainage system in order to remove runoff water from the roads and pavement and avoid flood condition.

How did Mendel’s results from dihybrid crosses help him develop the law of independent assortment?
Explanation:
The out come that mendel's observed from dihybrid crosses confirmed that each trait could be described by a pair of factors that segregated to form progeny (his first law) and further suggested that factors for multiple traits segregated independently, thus forming the basis for mendel's second law of inheritance
Hope this will help you analyse your answer
Mendel crossed plants with two different features. He proposed the Law of Independent Assortment because the ratio showed that the inheritance of one trait is independent of the inheritance of another.
Mendel conducted studies to investigate the simultaneous inheritance of two distinct features, such as seed color and seed texture.
He combined plants that were different in both qualities, for example, a plant with smooth texture and yellow seeds crossed with a plant with wrinkled texture and green seeds.
The qualities Mendel was seeing separated independently of one another, indicating that the inheritance of one feature did not affect the inheritance of the other.
In other words, during gamete production, the alleles for seed colour and seed texture were assorting separately.
Thus, Mendel proposed the law of independent assortment, which is one of the cornerstones of inheritance, as a result of his dihybrid crosses and the observation of independent segregation of characteristics.

An experimental diagram is shown in the diagram below:
a. Green water plants release a gas in the presence of light.
b. Roots of water plants absorb minerals in the absence of light.
C.Green plants need light for cell division. d. Plants grow best in the absence of light.
Answer:
Answer is A
Explanation:
This is because light energy is needed for plants to carry out photosynthesis. When plants photosynthesize, they absorb carbon dioxide gas and give out oxygen gas.
An experimental diagram is shown in the diagram below is Green water plants release a gas in the presence of light. The correct option is C.
Thus, When used to water plants, green water can offer important nutrients that can promote plant growth.
Algae are the cause of green water. An aquatic plant called algae includes chlorophyll, which gives it a green tint.
The water's high nutritional content and light are essential for algae growth, which gives the lake its green color and serves as a valuable source of nutrients for plants.
Thus, An experimental diagram is shown in the diagram below is Green water plants release a gas in the presence of light. The correct option is C.

The broadest areas of the plant that absorb the most sunlight are the:
1. roots
2. stems
3. leaves
Answer:
Leaves
Explanation:
Plants grow broad leaves to absorb sunlight. This is extremely helpful because this helps plants make food through photosynthesis. Roots don't absorb sunlight. They absorb water and nutrients from the soil and carry it up through the stems. The stems then transports the nutrients throughout the plant.

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1.0 mol per dm^3 sodium chloride solution
Explanation:
The idea behind this question is that the water inside the potato stick would move into the surrounding liquid naturally if the density outside the stick is greater than it is inside. Therefore, the liquid that would most encourage the flow of water from the potato stick would be the moet dense liquid- which in this case, is 1.0 mol per dm^3 sodium chloride solution.

describe the effect of magnesium deficiency on the transport of sucrose out of the leaves and the sucrose concentration out of the leaf
Answer:
The impact of diminishing the convergence of magnesium salt on the development of S.polyrhiza is because the low mg accessibility keeps an eye on troublesome sucrose exportation, making leaves hold sucrose three to multiple times more than the leaves of plants that get Mg in satisfactory inventory, showing that the inadequacy of this supplement causes extreme hindrance of sucrose transport.

why saturated solution prepared at higher temperature gives crystal on cooling
Answer:
Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.
Explanation:
It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.
describe about nutrition in human being
Answer:
Nutrition In Human Beings. Nutrients are the substances in food that maintain the body and make it work. Most of what one eats is made up of carbohydrates, proteins, and fats. Nutrients needed in smaller amounts, but still vital, are vitamins and minerals.
Explanation:
Hope it's answer you plz mark as Brainlist
The human being has a heterotrophic nutrition. Nutrition is realised by digestion. Digestion can be either intracellular or extracellular. Intracellular digestion occurs for example when white blood cells consume pathogens or dead tissue. Extracellular digestion occurs in the digestive tract. Digestion can be either mechanical(chewing) or chemical(hydrolysis-a process in which for every broken bond a water molecule is added).
The main types of nutrients are:
Carbohydrates that are mainly used for energy. In the digestive tract there are different enzymes that hydrolyse the carbohydrates to monosaccharides.
Carbohydrate----(enzyme)--->monosaccharide
Proteins play an important structural and functional role in the body. There are specific enzymes that digest them. They are broked down to amino acids.
Protein-------(enzyme)---->amino acid
Lipids store energy. There are enzymes that break lipids down to fatty acids and glycerol.
Lipids----(enzyme)--->fatty acids+glycerol
Vitamins help the metabolism and are not chemically processed in the digestive tract nor are minerals or water.

The Earth's tilt also causes the Sun's radiation to strike the _____ at different _____.
Answer:
hemispheres; angles
Explanation:
When a hemisphere—either northern or southern— is tilted toward the sun it has more hours of light compared to the hemisphere tilted away from the sun. Moreover, lower latitudes where the incoming solar radiation is more direct (angle closer to 90°) receive more radiation compared to higher latitudes where sunlight strikes at lower angles. The combined effect of more hours of daylight and more direct radiation in the hemisphere tilted toward the sun generates warmer temperatures compared to the hemisphere tilted away from the sun.
