30 percent is going to be cytosine, because 20% of adenine, plus 20% of thymine, and that leaves 60% for both guanine and cytosine,
They produce food with energy from the sun
When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.
Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.
Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.
There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.
It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

Plants are very crucial for maintenance of balance of ecosytem as part of the equilibrium and the primary basis for the ecosystem as the producers.
Explanation:
The ecosystem consists of plants with animals and the environment surrounding it. The balance of all three elements is essential for the co existence of the ecosystem. devoid of any or excess of either factor will lead to destruction.
The imbalance so caused will lead to over production or over consumption of the strata in the ecosystem. Plants holds the producer level of the ecosystem which forms the basis to all, if dis-balanced all the factors relying on it will decline eventually and the world will fall.
