Arrange the steps of energy production in the correct order.
Ulleksa [173]
Here are the correct steps involved in energy production: 

<span>Step 1 - Consumption of food
Step 2 - breakdown of starch into glucose
Step 3 - absorption of glucose molecules
</span>Step 4 -cellular respiration in mitochondria<span>
Step 5 - creation of ATP

ATP is the end-product of aerobic respiration and this occurs in living organisms as soon as they have begun metabolizing the food that they have consumed.</span>

Vikki [24]

Answer:

The appropriate answer is "72.8 m".

Explanation:

Let the distance be "x".

As per the question, we get

⇒ T_{Mia}=T_{Brandi}

or,

⇒ \frac{x}{13} +\frac{x}{7}=\frac{\80}{10} +\frac{80}{10}

By taking L.C.M, we get

⇒ \frac{20x}{91}=16

By applying cross-multiplication, we get

⇒ 20x=1440

⇒     x=\frac{1456}{20}

⇒        =72.8\ m

<h3>What is a Parachute?</h3>

This is a device used to slow the motion of an object through an atmosphere by creating drag.

The size of the parachute affects the speed of falling because a larger parachute allows it to displace more air, causing it to fall more slowly. The one with three parachutes which is A will fall slowest and the one with just one will fall fastest.

andre [41]

Answer:

the frequency is the fundamental and distance is    L = ¼ λ

Explanation:

This problem is a phenomenon of resonance between the frequency of the tuning fork and the tube with one end open and the other end closed, in this case at the closed end you have a node and the open end a belly, so the wavelength is the basis is

          λ = 4 L

In this case L = 19.4 cm = 0.194 m

let's use the relationship between wave speed and wavelength frequency and

           v = λ f

where the frequency is f = 440 Hz

           v = 4 L f

let's calculate

           v = 4 0.194 440

           v = 341.44 m / s

so the frequency is the fundamental and distance is

                  L = ¼ λ
