Answer:
The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).

Answer:
"<em>Methane is a greenhouse gas, so its release would likely increase global warming."</em>
Explanation:
Methane is a greenhouse gas, so its release would likely increase global warming.
This is the only one that is both "true," and that applies to climate scientists.
Methane is toxic to marine organisms and would damage the ecosystem if released by killing species.
We are asking about <u><em>climate scientists.</em></u>
This would lead to massive pollution of drinking water.
We do not get drinking water from the ocean (except in some desert countries).
We want to extract and use this gas as a fuel source, but it would be lost to the environment through this process.
Again, climate scientists.
