Option (III) .Cephalization, the clustering of neurons and interneurons in the anterior part of the animal, is apparent in <u>Planaria.</u>

What is planaria?

  • Planaria is a genus of planarians in the family Planariidae.
  • When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
  • Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
  • The testes occur along the whole body.
  • Planaria originally have habitats in dark, murky water which results in such sensitivity .
  • They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
  • Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).

Eric follows a vegetarian eating pattern, and he wants to know whether he needs to take any vitamin and mineral supplements. wha
Reil [10]

It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or  riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.

A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.

Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.

How would the inability to make saliva affect digestion?
irina [24]
I believe the inability to make saliva would affect digestion drastically. The first phase in the process of digestion comes with saliva - it breaks down some substances in your mouth, because it contains amylase which helps during this process. If it weren't for saliva, you probably wouldn't even be able to swallow food - and even if you did, it would be almost impossible to break it down in your body.
