There is  no such thing as pure water, when you  buy bottled water you think you're buying pure water but it's the same water.

I'm not going into the scientific facts here but the truth is 'pure' water does not exist because that means the water will have NOTHING in it which means they will have to remove the natural minerals and then the water will interact with any organic materials the water encounters, including air and plastic. 

<em>But the water is clean and healthy to drink. Just not pure.</em>

There is a lot of pollution, dirts and organism inside water. This tells us that water is not pure. Hence, we can make it drinkable and suitable to the mouth. Not by adding chemicals because chemicals can make it not good or drinkable and can cause harm to the human body. We purify water by filtering it with the tools required. Hope this helps! :)

What can be said about the polarity of water
Ierofanga [76]
Water's polarity can be responsible for many of it's properties including it's attractiveness to other molecules.  Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of the other. Also the unequal sharing of electrons gives the molecules a slight negative charge near it's oxygen atom and a slight positive charge in it's hydrogen molecule.

The R locus determines flower color in a new plant species. Plants that are genotype RR have red flowers, and plants that are rr
tatiyna

Answer:

The correct answer will be- Non-Mendelian inheritance (incomplete dominance)

Explanation:

Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.

In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.

Cross

RR (red) x rr (white) = Rr (pink)

Thus, incomplete dominance is the correct answer.
