Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
The answer is B. Platypus, as they are mammals that lay eggs.
Homologous structures are common structures in different species that perform different functions and may have look similar in structure.
Example- The different animals have bones that appear very similar in form and function and seem to be related.
They use both there really isnt a big difference
Scientists are still doing research and we just need to be patient. :) :)
