Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 7mm from

ZanzabumX [31]

Answer:

With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).

Explanation:

According to this question:-

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we gage the photosynthesis rate in hr.

Radiation can cause breaks in human chromosomes. However, insects can survive much higher lecels of exposure. Why?

galben [10]

Explanation:

The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .

As the target of the radiation is the DNA .

Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
