Answer:

\frac{15}{4} pounds of cheese Sam had bought altogether.

Explanation:

Mass of Swiss cheese bought by  Sam = 2\frac{1}{4}=\frac{9}{4} pounds

Mass of cheddar cheese bought by  Sam = 1\frac{1}{2}=\frac{3}{2} pounds

Total mas of cheese bought by Sam:

\frac{9}{4} pounds+\frac{3}{2} pounds

=\frac{9\times 2+3\times 4}{4\times 2} pounds=\frac{30}{8} pounds=\frac{15}{4} pounds

\frac{15}{4} pounds=3\frac{3}{4} pounds

\frac{15}{4} pounds of cheese Sam had bought altogether.

List the sub-atomic particles in the order in which they were discovered and tell who discovered each one.
harkovskaia [24]
<span>Photons were the first sub-atomic particles detected, but not quite discovered as they could not be explained. Photons were first detected by Johann Wilhelm Ritter, Victor Schumann, and Winhelm Rontgen. The next, and first sub-atomic particle discovered, was the electron. The electron was discovered by J. J. Thompson in the late 1800s. The next two sub-atomic particle discoveries were the alpha particle and photon, discovered by Ernest Rutherford and Paul Villard respectively. Rutherford also discovered the proton and in 1932, James Chadwick discovered the neutron.</span>

Which statement describes the energy involved in diffusion? Diffusion requires energy in all cases. Diffusion requires energy on
MArishka [77]

Answer:

Both b and d can be correct

Explanation:

Generally, diffusion does not require energy (<em>making option a wrong</em>) because it is the movement of particles from a region of high concentration to a region of low concentration hence diffusion moves particles in the direction of a concentration gradient. An example of this is the passive transport (for instance, uptake of glucose by a liver cell).

However, in some cases, when diffusion is against the concentration gradient (i.e when particles move from a region of low concentration to a region of high concentration), diffusion will require energy in a case like this (<em>making option c wrong</em>). An example of this is active transport (transport of protein called sodium-potassium pump which involves pumping of potassium into the cell and sodium out of the cell).

The explanation above shows that diffusion can require energy to move particles (in or out) of the cell through the cell membrane.
