Sarah's class is studying soils. Her teacher, Ms. Jones, stated that plants will growth in any soil type. Students in Sarah's cl
ass performed an experiment to see if Ms. Jones' statement is true. When they started the experiment, the students used the same type of plants, and all of the plants were the same size. Sunlight, amount of water, and air temperature were the same for all pots; only the soil type was changed. The results are seen in the table. Ms. Jones was partially correct: all the plants DID grow but not at the same rate. What conclusion can be drawn from the three test pots of soil? A)The bigger the soil particle size, the better the plant growth.
B)Plants grow best in soils that are a mixture of sand, clay, and loam.
C)The smaller the soil particles, the more water and air available for plant growth.
D)Sandy holds water for short periods of time; low water means less plant growth.
The answer in c. I think this because it’s the most logical answer, and based on my experience with plants, the smaller the soil particles, the more air and water is available! I hope this helps:)
The main difference between the two models is <em>the position of the electron in the atom</em>.
Explanation:
<em>Bohr model:</em> The electrons are moved around the nucleus in circular definite paths (orbitals or shells). Also, he could not find or detect the exact position of electron.
<em>Electron cloud model:</em> It is supposed by Erwin Schrodinger. He showed that the emission spectra of the atom is the way to detect the probability of electron position.

are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. So, we calculate as follows:
Molarity = 15.9 g BaCl2 ( 1 mol / 208.23 g ) / .375 L = 0.204 mol / L</span>
