Epinephrine and norepinephrine, together called catecholamines, are referred to as _______________ hormones and dramatically __________ concentrations during moderate-intensity exercise.

Neurons can be divided into three basic components

Tracking changes in plasma volume before, during and after exercise can be important to quantify the impact on hormone concentrations in the blood. Scientists often estimate changes in blood plasma volume by measuring_________ and_________ before and after a bout of exercise.

Consider the implicit constraint C(x, y) = sin(x) − y = 0. Let q = (x, y). Compute the Jacobian J = ∂C/∂q at the point (x, y) = (0, 0), and report the sum of the components of J. Answer with a single number.

Two cubic Bézier curves (V0, V1, V2, V3) and (W0, W1, W2, W3) are joined with C2 continuity at the shared point. For the Given points below, compute W1 and report W1.x + W1.y V0 = (0, 1) V1 = (1, 4) V2 = (3, 2) V3 = (5, 6) Hint: V3 = W0 V3 − V2 = W1 − W0 V1 − 2V2 + V3 = W0 − 2W1 + W2

Consider the differential equation ẋ = λx where λ = i. We integrate this system using the Explicit Euler method. Which time step h makes the method stable?

Lectura Read Victoria’s e-mail, then answer the questions.  Hola, Marcela:¿Recuerdas el complejo deportivo (sports complex) que está al lado del estadio? Voy todos los fines de semana porque puedo hacer muchas actividades. Este fin de semana hay partidos de tenis, fútbol y baloncesto para niños y adultos. También hay paseos en bicicleta por el parque todas las mañanas. Yo nado por las tardes en la piscina. Varias chicas de la universidad también vienen los fines de semana. Puedes practicar todos los deportes menos (but) golf. Si quieres, te consigo una invitación.Hasta pronto,Victoria 2. ¿Qué pasa este fin de semana?
