Put the following steps of the sliding filament theory in the correct order.

1. action potential arrives at the axon terminal

2. sodium diffuses into the muscle fiber

3. myosin binds to the active site on actin

4. acetylcholine is released into the synaptic cleft

5. calcium binds to troponin

6. calcium released from the terminal cisternae of the sarcoplasmic reticulum

7. troponin/tropomyosin complex changes shape, opens active site on actin

Antoine manages a number of apartment buildings that use natural gas for heating, cooking, and laundry. the scatter plot shows the correlation between the outside air temperature and antoine's natural gas bill. which type of correlation does the plot illustrate?

14) 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.
