In an isometric contraction, how can the muscle stay the same length when the muscle is contracting? a. Elastic elements of the muscle stretch in response to the contraction of the muscle, so that the muscle stays the same size despite shortening sarcomeres. b. The myosin heads detach from actin when they reach the desired length. c. Calcium stops entering the sarcoplasm when the desired length is reached. d. The muscle is not able to generate more (or the same amount) force than the load, preventing shortening of the muscle.

In 2009, a flu pandemic was believed to have originated when viral transmission occurred from pig to human, thereby earning the designation, "swine flu." although pigs are thought to have been the breeding ground for the 2009 virus, sequences from bird, pig, and human viruses were all found within this newly identified virus. what is the most likely explanation of why this virus contained sequences from bird, pig, and human viruses? a) the virus was descended from a common ancestor of bird, pig, and human flu viruses.b) the infected individuals happened to be infected with all three virus types.c) related viruses can undergo genetic recombination if the rna genomes mix and match during viral assembly.d) the human was likely infected with various bacterial strains that contained all three rna viruses.
