While inspecting the genome sequence of your newly discovered organism, you note that while the genome overall is 50% G + C, there is a cluster of genes comprising about 20,000 bp that is 64% G + C. The best explanation for this is:A) this represents normal variation within a chromosome. B) the 20,000 bp segment likely contains a cluster of housekeeping genes. C) the 20,000 bp segment is an adaptation to a more thermophilic environment. D) the 20,000 bp segment is a recent acquisition via horizontal gene transfer.

What do all macromolecules have in common with each other? oa. they all are formed from the same elements.ob. they all have major roles in cell membranesoc. they all act as catalysts in the body.od. they all have peptide bonds between carbon atoms.

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
