Answer:
muscles,glands
Explanation:
The part of the body that responds to the stimulus is called an effector organ. The peripheral nervous system is made up of sensory nerves that transmit impulses from the receptors in sensory organs to the central nervous system and motor nerve that transmits impulses from central nervous system to effector. The central nervous system receives and integrates impulses from the receptors and the relays them to the effector organs.
If the purple plant was homozygous dominate then it can only pass along a dominate allele to its offspring so despite the genotype of the other parent 100% of the offspring will reprsent a purple phenotype.
The fossil record is the type of evidence that is used with molecular clocks to estimate the split from a common ancestor.
<h3>What is a molecular clock?</h3>
A molecular clock is an estimation of the times of divergence used for the study of biological phenomena.
Molecular clocks are based on fossils found for a given species and the mutation rate of a given genomic sequence.
In conclusion, fossils are used as point of reference to build molecular clocks based on the mutation rate of homo-logous nucleotide sequences for a given taxonomic group for which these fossils belong.
