Why is water colorless?
It is actually not. It is weakly blue which becomes apparent when a lot of it is gathered in one place. It is definitely not very strongly colored though. That is very common. Very few pure simple substances are strongly colored. Pure salt and sugar are transparent and colorless too. In bulk they look white because the tiny crystals scatter light, but snow does the same. A liquid forms one homogeneous mass.
In nature, of course, substances are rarely pure. Therefore not so many things look colorless. It only takes a little bit of a strongly colored impurity to color the whole thing. Just look at Himalaya salt or unrefined sugar or orange juice.
Why is water tasteless?
Because we don’t need to taste it. We get a good idea of the water content of food from the feel of it. Other liquids are usually oils, which feel very different. Besides it is not all that important exactly how much water is in one particular food item, if we need hydration then we drink stuff which is definitely mostly water.
The sense of taste not registering water frees up capacity to detect other things.
Why is water odorless?
Likewise because we don’t need to smell it. There is no real evolutionary advantage to be able to instantly tell the moisture content of the air. Better to use the sense of smell to detect poisons, food nearby, relatives or strangers etc. than to tell how the weather is today. We can tell how the weather is by other means.

Answer:
GAA TTC GCA Original strand
CTT AAG CGT Complimentary strand
Explanation:
The original strand is already given. It is GAA TTC GCA
Now we need to recognize the complementary strand from the pool of options and pair their bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines.
- Adenine (A) and guanine (G) derive from purines,
- Thymine (T) and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Knowing this, we need to find the correct option, which will pair A with T and C with G.
- 1st Strand → CUU AAG CGU → You can eliminate this option because it includes Uracil, which is a base of RNA. Uracil complements with Adenine, but only in RNA, and now we are looking for a DNA complementary strand.
- 2nd Strand → GAA CCT CAT → None of the triplets pair correctly the original strand. It is not complementary
- 4rth Strand → GAA TTC GCA → This is equal to the original strand. It does not complement it.
- 3rd Strand → CTT AAG CGT → The three triples complement the ones of the original strand. This is the correct option.

<u>genome</u>
The collection of all the genetic material (the DNA) in a cell or organism is called the <u>genome</u>.
- The total collection of DNA instructions present in a cell makes up the genome.
- The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.
- Everything a person needs to grow and operate is encoded in their genome.
<h3>What makes the genome significant?</h3>
- Three billion base pairs of DNA make up the whole human genome, which is uniquely structured to give us our basic anatomy and unique traits like height and hair color.
- Understanding how genes function is essential for understanding how our bodies function and what occurs when we are ill.
- Genes are formed by DNA.
