Answer:
True
Explanation:
Sewage contains many substances in it like suspended solids, organic and inorganic impurities, nutrients, saprotrophic and disease causing bacteria and other microbes. Hence it is said to be a complex mixture.
Out of the following given choices;
mucosa
serosa
submucosa
muscularis externa
The answer is muscularis externa. This layer is one of the 4 layers (tunics) of the GI tract. It is found beneath the submucosa and is composed of smooth muscles. The smooth muscles are responsible for the involuntary movements called peristalsis, that move food along the gastrointestinal tract.
The cytoplasmic fragments of the megakaryocytes constitute the platelets, this fragments simultaneously into thousands of new platelet cells, these morphological changes are known as proplatelets.
<h3>What are proplatelets?</h3>
They are cytoplasmic protrusions from which platelets or fragments are going to be detached that end up maturing in the circulation.
<h3>Characteristics of proplatelets</h3>
- Platelets are formed from the fragmentation of giant cells, which emit cytoplasmic protrusions.
- Each megakaryocyte has about 6 proplatelets, and each proplatelet houses about 8,000 platelets, these "bags" full of platelets enter the bloodstream where they break, releasing them.
Therefore, we can conclude that the megakaryocytes form the future platelets, these platelets are grouped in cytoplasmic portions, called proplatelets.
