Answer:
Archaebacteria have cell wall made of complex composition of peptidoglycan
Land requirements are <u>much smaller</u> for meat protein production ( B )
Production of sufficient soybean protein requires the plantation of enough soybean seedlings and this plantation requires vast amount of land ( in acres ) while meat protein production can be done using several methods such as :
- Open grazing and
- Ranching
which makes the use of Land for meat protein production when compared to soybean protein production smaller. Also The amount of protein per animal is larger when compared to the amount of protein per soybean plant.
Hence we can conclude that Land requirements are <u>much smaller</u> for meat protein production.

<span>Sunset, this is really similar to the question about molecular clocks you asked. The more closely related the three species are, the more similar the homologous proteins will be in each of the species.
Defining 'sequence similarity' is a little bit nuanced. It can refer either to the genetic code or the amino acid code. Because the genetic code is degenerate multiple codons code for the same amino acid - mutations in the gene don't result in mutations in the proteins when the mutated codon codes for the same amino acid as the unmutated codon.
Similarly, you can sort of think of some amino acids as being redundant. In some cases, replacement of one amino acid with another doesn't result in all that much change to the protein's structure or function. The result is, as species diverge and mutations build up, they build up preferentially in certain domains of the protein and more frequently involve replacement of one amino acid with one which is pretty much similar to it.</span>
