Planarians lack dedicated respiratory and circulatory systems. This deficiency does not cause a problem because ________.

Biology
1 answer:
ZanzabumX [31]3 years ago
6 0

Answer:

Most cells within planarians tend to be very close to their gastrovascular cavity, in addition to their external environments. Also, planarians have the ability for oxygen and carbon dioxide to diffuse through the cells on their body walls: this makes it unnecessary for these varieties of flatworms to need a dedicated bodily system.

I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm. 

hope this helps!!!!!....

Forming glycogen as energy storage in the liver is an example of ________.
lorasvet [3.4K]

Forming glycogen as energy storage in the liver is an example of anabolism.

<h3>What is anabolism?</h3>

Anabolism is a metabolic process that consists of the construction and manufacture of more complex molecules from simpler molecules. This contributes to cell growth and energy storage for tissue maintenance.

The process of anabolism can be seen in processes such as the formation of triglycerides or glycogen for energy reserves within cells or in the formation of muscle proteins, given in the sports world.

In these anabolic processes, a lot of energy is consumed since much more complex molecules are being manufactured.

It is a totally opposite and complementary process to catabolism, in which these complex molecules are broken down into much simpler molecules and the release of energy is generated.

For a correct homeostasis of the body, these two processes have to be balanced and work in a <u>complementary way.</u>

Therefore, we can confirm that forming glycogen as energy storage in the liver is an example of anabolism.
