Answer:

2.67 cells at 500x magnification...

Explanation:

So, four cells are present at 200x magnification and are covering the full diameter of lens. by using a 500x magnification, it means that magnification is increased 1.5 times. So, the number of cells visible will be decreased by a factor of 1.5. So, decreasing 4 cells by a factor of 1.5 means <em>2.66666666667</em> or <em>2.67</em> cells at 500x magnification. Resolution has to be increased by a factor of 1.5 to produce a view-able clear image of cells.

How is a frog disected?
Stella [2.4K]
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>

Which wavelengths of light drive the highest rates of photosynthesis? Select the two best answers.
Lilit [14]

Answer:

  • 400-450 nm
  • 550-700 nm

Explanation:

Chlorophyll pigments (mainly chlorophyll a and b) absorb the red and blue spectrum of visible light in the electromagnetic spectrum for photosynthesis. This is why leaves appear green (and occasionally orange) because this visible light portion is not absorbed. The blue light absorbed by leaves ranges between 400 – 450 nm while the red light ranges between 500 nm and 700 nm.
