Answer:

A. What length of time is best to use for the firing of pottery to make it strong?

Explanation:

Point A

What length of time is best to use for the firing of pottery to make it strong?

This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.

Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.

Hence, option A is the correct answer.

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.

In an electrochemical cell, q = 0.0010 and k = 0.10. what can you conclude about ecell and e∘cell? in an electrochemical cell, =
Iteru [2.4K]
If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive

Which is an example of the use of plants in human society? Fossil fuel usage causes the elimination of carbon sinks. Plants make
padilas [110]

I believe the answer is plants make flowers to attract insects because, plants do nit store carbohydrates, meat does, and we cant use plants to create fossil fuel. The only plant fibers we use for clothing is cotton so that is very limited in the wide aspect of things.

Which of the following is a necessary reactant for cellular respiration to occur?
IrinaVladis [17]
I believe the correct answer from the choices listed above is the third option. It is oxygen that is a necessary reactant for cellular respiration to occur. Cellular respiration, in a sense, is breaking down sugar in the presence of oxygen.  Hope this answers the question.
