For a given species, an increased evolutionary rate would cause a decrease in a) biodiversity. b) fitness of a species. c) similarity of the individuals in the species. d) the number of new genes in the dna of the species.

The diagram illustrates the activity of vesicles during a cellular process.

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell

The concept of keystone species is controversial among ecologists because most organisms are highly interdependent. if each of the trophic levels is dependant on all others how can we say one is most important
