A group of students uses a pitfall trap for capture and release of rare stag beetles. Which of these situations would NOT cause an error in estimating the population size? A. Stag beetles have a larval stage in their life cycle, which was not caught by the pitfall traps. B. The stag beetles were infected with a fungal pathogen and a large number died between weeks one and two. C. The stag beetles could not disperse widely in the week between samples. D.

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.
