Off the top of my head, I only know 9 and 11, so I'll answer those two.

9) A heterotroph is an organism that relies on other organisms for food/energy
    An autotroph can produce its own food from inorganic compounds (light)

11) Vascular plants have specialized tubes for transporting nutrients
      Nonvascular plants do not have such tubes and are simpler

One end of rod A is placed in a cold reservoir with a temperature of 5.00°C. The other end is held in a hot reservoir at 85.0°C.
slavikrds [6]

Answer:

1 / 2

Explanation:

This problem is a 1 - D steady state heat conduction with only one independent variable (x).

1 - D steady state:

Q = dT / Rc

Q = heat flow

dT = change in temperature between a pair of node

Rc = thermal resistance

Rc = L / k*A

Since in both cases Rod A and Rod B have identical boundary conditions:

dT_a = dT_b

So,

R_a =  L / k*(pi*r^2)

R_b = 2L / k*(pi*(2r)^2) = L / k*(2*pi*r^2)

Compute Q_a and Q_b:

Q_a = k * dT *(pi * r^2 * / L)

Q_a = k * dT*(2*pi * r^2 * / L)

Ratio of Q_a to Q_b

Q_a / Q_b = [k * dT *(pi * r^2 * / L)] / [k * dT*(2*pi * r^2 * / L)] = 1 / 2

Which type of reaction does this diagram represent?
victus00 [196]

The diagram represents a chain reaction that is caused by nuclear fission

<h3>What is a chain reaction?</h3>

A chain reaction is simply a sequence of reactions in which a reactive product or a by-product causes additional reactions to take place.

<h3 /><h3>What is nuclear fission?</h3>

Nuclear fission is a type of reaction in which the nucleus of an atom splits or divides into smaller nuclei.

From the diagram, it can seen that larger atoms where divided into smaller ones which resulted in additional reactions.

Hence, the reaction is a chain reaction cause by nuclear fission.
