<u>Answer:</u>
Free-living flatworms have developed a nervous system which helps them to sense the food. They have a head at one end of the body and each side of the head has sensory cells. These cells help them to sense chemicals and other movements around them.
While Parasitic flatworms don't have any nervous or digestive system as they live on the food digested by the host. They have special hooks attached to their head which help them to attach a host. They have developed some covering called 'teguments' which protect them from digestive liquids.
They are found in the center of the osteon within a long opening called the Haversian canal.
Answer:
B) Phenotypic Ratio
Explanation:
Phenotype is the Visible expression of a Character
Also, with the help of a punet's square we will come to know to the Phenotypic Ratio is 3:1 where the purple flowers are dominant to white flowers where as if we take a Genotypic ration it doesn't show the Visible expression of a character, it only shows the genitical constituion of a character! If we take "percents", then it could be the Genotype "Percents" or Phenotype "Percents"
