Answer:

Do NOT attempt to fill a buret precisely to the 0.00-mL mark at the top. This is a waste of time, as all volumes delivered by a buret are determined from the difference between initial and final readings. This step is important because the hanging drop is part of the volume delivered by the buret.

The correct answer for the question that is being presented above is this one: "B) the peripheral route to persuasion."

What types of materials are expelled from cells during exocytosis?

denis23 [38]

Answer:

Large molecules such as hormones

Explanation:

The other options either have channels within the membrane to move through (water has aquaporins, ions like potassium have their own channels) or can diffuse directly through the membrane (CO2). Protein hormones cannot move through the plasma membrane, nor can they diffuse through it. Hope this helps!

Slope integrals for calculus, having trouble need all the help I can get

Harlamova29_29 [7]

(1) The integral is straightforward; x ranges between two constants, and y ranges between two functions of x that don't intersect.

$\displaystyle\int_{-2}^1\int_{-x}^{x^2+2}\mathrm dy\,\mathrm dx$

(2) First find where the two curves intersect:

y ² - 4 = -3y

y ² + 3y - 4 = 0

(y + 4) (y - 1) = 0

y = -4, y = 1 → x = 12, x = -3

That is, they intersect at the points (-3, 1) and (12, -4). Since x ranges between two explicit functions of y, you can capture the area with one integral if you integrate with respect to x first:

$\displaystyle\int_{-4}^1\int_{y^2-4}^{-3y}\mathrm dx\,\mathrm dy$

(3) No special tricks here, x is again bounded between two constants and y between two explicit functions of x.

$\displaystyle\int_1^5\int_0^{\frac1{x^2}}\mathrm dy\,\mathrm dx$
