<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
Habitat it would be because that is animal nature
Answer:
A. Coevolution
Explanation:
Coevolution occurs when two species/organisms reciprocally affect the evolution of one another. An example is the coevolution is flowering plants and associated pollinators (e.g., bees, birds, and other insect species). Moths benefit form nectar and orchids benefit from pollinaton.
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
