These polycyclic steroid hormones have a variety of roles that are crucial for the body’s response to stress, and they also regulate other functions in the body.

Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
Answer:
En 1892, su método sirvió para resolver, por primera vez en la historia, un homicidio mediante evidencia de huellas dactilares en la escena del crimen. Los hijos de una mujer llamada Francisca Rojas habían sido asesinados, y ella misma había señalado como responsable a un hombre al que había rechazado como marido. Los agentes de policía no lograron arrancarle una confesión al sospechoso aun sometiéndolo a torturas, así que se pusieron a investigar a fondo y encontraron una huella ensangrentada en una puerta.
Al cotejarla, descubrieron que la asesina no era otra que la madre, que, ante la evidencia, acabó confesando. El jefe de la Policía no tardó en adoptar oficialmente el Sistema Dactiloscópico Argentino, como posteriormente se conocería, lo que convirtió a Argentina en el primer país en depender únicamente de las huellas dactilares como método de identificación. A principios del siglo XX, el sistema de Vucetich empezó a difundirse por todo el mundo.
Explanation:
a nurse is teaching a group of clients about risk factors for heart disease. The nurse include that Obesity, Hypertension increase a client's risk for a myocardial infarction (mi).
<h3>What is
myocardial infarction ?</h3>
The heart muscle starts to die as a result of inadequate blood flow during a heart attack, which is medically referred to as a myocardial infarction. Typically, a blockage in the arteries supplying blood to your heart is what causes this.
<h3>Causes of
myocardial infarction :</h3>
The primary cause of death in the US, coronary artery disease, is to blame for the majority of myocardial infarctions. The myocardium is deprived of oxygen when coronary arteries are blocked. Myocardial cell loss and necrosis can result from a prolonged lack of oxygen flow to the myocardium.
