<h2>Natural selection</h2>
Explanation:
Natural selection acted up on gene,prevents the gene from acting as a reliable molecular clock
- Molecular clock measures the number of changes,or mutations,which accumulate in the gene sequences of different species over time;proves to be a valuable tool for estimating evolutionary timescales
- Natural selection is simply a concept of evolution where organisms with favorable traits are more likely to reproduce
- When natural selection is acted up on a gene governing the molecular clock then that gene won't be reliable because natural selection favors only the dominant gene
- The one's which are dominant and have desirable characteristics are favored under natural selection rest all species are eliminated whereas molecular clocks takes into the consideration the gene sequences of different species and the mutations occurring(irrespective of dominant or recessive species)
- Therefore natural selection will prevent the gene to work as reliable molecular clock whereas neutral mutation forms a base for molecular clocks
Here is your answer
1. Insulin (it reduces the level of sugar in blood)
2. Glucagon (it converts glycogen into glucose, thus increasing the sugar level)
Both are secreted by pancreas.

C. carbon, hydrogen, and oxygen
The population of beetle will increasingly become green, with subsequent generations, until it becomes the dominant phenotype. This is because the green beetles will be able to camouflage with their environment and avoid being preyed on by the birds as compared to the black beetles. Therefore, the green beetle will have a high chance of reaching the reproductive stage and passing its genes to the next generation as compared to the black beetle.
