Answer:

The 19 is A and the 20 is D

Explanation:

Work done is N *m

So it gonna be 20N*5m

Giving 100J

The 20 work is only done when the object sets into motion

Explanation:

For question no 19

Force (F) = 20N

distance (d) = 5m

Work = F * d

= 20 * 5

= 100 J

Now

For question no 20

D. No matter how much force is applied the object must have motion for work to be done.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

What happens to energy that is released from food, but not captured and store into<br> ATP?
nignag [31]

Answer:

In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without. During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down.

11. Are fungi more closely related to<br> plants or to bacteria?
hodyreva [135]

Answer:

Computational phylogenetics comparing eukaryotes revealed that fungi are more closely related to us than to plants. Fungi and animals form a clade called opisthokonta, which is named after a single, posterior flagellum present in their last common ancestor.
