Answer:
The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.
Explanation:
Annelids, such as the earthworm, have a variety of sensory cells:
- <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.
- <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
- <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
- <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.
The tegument is very rich in free nervous terminations, which functions might be tactile.
the ability to reproduce.
Answer:
stored solar energy in phytoplankton, zooplankton, and other organic material
Explanation:
The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.
Answer:
hemotrophs are organisms that obtain energy by the oxidation of electron donors in their environment. Chemoautotrophs use inorganic energy sources to synthesize organic compounds from carbon dioxide. Chemoheterotrophs are unable to utilize carbon dioxide to form their own organic compounds.
