Answer:
C) 34%
The other two samples are-
Gravel- D) 38%
Silt- B) 53%
Explanation:
To find the porosity of the sample, you do (volume of fluid)/(volume of substance) X 100. We were given a 300mL sample of sand, and 400 mL of water. You must also take account of how much surface water is found, which you add to however much water you put into the 300mL sample.
Gravel has the highest permeability, and silt has the lowest.
Plants make their own food by a process called Photosynthesis. ... Photosynthesis is done with the help of carbon-dioxide, water, and sunlight. The end products of photosynthesis are oxygen, which the plants release, and carbohydrates, which become the plants' source of energy
<span>Gene Expression is the progression wherein the
information from a gene is used in the combination of a functional gene
product. In eukaryotic cells, genes are delimited by repressors as well as by transcriptional
activators. The repressors will muddle to the specific DNA sequences and will constrain
transcription.</span>
They are Nucleic Acids, Proteins, Carbohydrates, and Lipids
