Samuel wanted to test how well three types of soil holds water. he poked several small holes in the bottoms of three plastic cups and filled one with sand, one with clay, and one with loam. he set each cup of soil inside a slightly smaller cup, like in the picture shown. he poured the same amount of water into each cup of soil and came back one hour later to measure how much water had dripped through each soil. the following amounts of water were found at the bottoms of the smaller cups.

sand: 4 ml
clay: 0 ml
loam: 2.5 ml

based on this information, which statement is true?
a) he poured the most water into the cup containing sand.
b) he did not pour any water into the cup containing clay.
c) clay retained the most water out of the three substances.
d) sand retained the most water out of the three substances.

C) Clay retained the most water out of the three substances

Explanation:

Based on this information, "clay retained the most water out of the three substances" is the statement that is true.  

The experiment was carried out to test the water holding capacity of the three types of soil. In this experiment, 0ml of water was found at the bottom of the smaller cup which contains the clay soil, while sand and loam soil has 4mls and 2.5mls respectively. Clay soil has 0ml of water at the bottom of the cup because it retained the most amount of water and has the highest water holding capacity than the other soils. Clay soil has smaller fine particles. The smaller a soil particles are, the larger the soil’s surface area is, and so the more water the soil retains. This is why clay soil retained the most amount of water in the experiment.

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
