Carlos will have to consume about 63 gram of protein per day.
The dietary reference intake of protein is 0.8 gram of protein per kilogram body weight or 0.36 gram per pound. Carlos is 175 pounds in weight, so he is going to need 0.36 * 175 = 63. Thus, Carlos needs 63 grams of protein per day.<span />

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.
