7. application: have you ever had a cut before and wondered why it stops bleeding? it is actually a very complex process
that includes platelets, which make up a component of your blood. platelets are involved in the blood clot. as
platelets begin to assist in clotting, more and more platelets are activated by complex signaling. this continues until a clot
can be formed. is this signaling scenario best describing positive or negative feedback? why

When there is a cut, and platelets are coming, its positive feedback. But when the clot is formed and increased platelets concentration at the site create a negative feedback to stop sending more platelets for clot formation.

it's negative feedback mechanism

Explanation: because negative feedback is about to maintain normal condition of the body

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
