Number of protons in Uranium-235 is 92
Number of neutrons in Uranium- 235 is 143
Explanation:
Isotopes are the two or more elements having the same number of protons and electrons but different number of neutrons. They differ in their atomic masses.
The correct option is A.
In the question given above, we are told that the number of trees in the ecosystem is 1,000,000; this figure far outnumber that of all the other organisms in the ecosystem. The plants are the producers in any ecosystem and they serve as sources of food for all other organisms in an ecosystem. Based on the number of trees present in this ecosystem, the pyramid of number and the pyramid of biomass will be upright, this is bcause the number of producers far outnumber the number of the consumers. A pyramid of number or a pyramid of biomass is said to be inverted if the number of producers is less than that of the consumers.

It's not so important that it be recycled ... after all, there's almost a limitless supply,
and there's no danger of ever running out of it.
What's important is to keep carbon out of the atmosphere. In order to do that, we
need to reduce the amount of it that's released during so many of the processes
that we've been doing on a huge scale for the past 200 years, and invent ways
to capture the carbon that we DO continue to release, before it gets into the
atmosphere.
