Which wavelengths of light drive the highest rates of photosynthesis? Select the two best answers.
1 answer:
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.

Answer:
15 g
Explanation:
The density of an object can be found using the following formula:
We want to find the mass, so we must rearrange the formula for . Multiply both sides of the formula by
.
The mass can be found by multiplying the density and volume.
The density of the object is 1.5 g/mL and the volume is 10 mL.
Substitute the values into the formula.
Multiply. When multiplying, the milliliters, or mL will cancel out.
The mass of the object is 15 grams.
