Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.

Answer:

C would be the incorrect statement.

Explanation:

When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.

Hope this helps :)

The majority of the world's energy is produced by burning fossil fuels. Fossil fuel combustion results in the release of carbon
Drupady [299]

The correct answer is option B, that is, the release of large amounts of greenhouse gases can change Earth's climate.

Fossil fuels refer to hydrocarbons, mainly fuel oil, coal, or natural gas, produced from the leftovers of dead animals and plants. The use of fossil fuels has allowed large-scale industrial development and hugely supplanted water-driven mills, as well as the combustion of peat or wood for heat.  

The burning of fossil fuels by humans is the biggest source of emissions of carbon dioxide that is, one of the greenhouse gases, which permits radioactive forcing and donates to global warming. One of the dreadful effects of global warming is the change in the climatic condition of Earth.

dem82 [27]

Hey there! :D

When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".

I hope this helps!
