I believe it is D as it is a better answer than D because of the fact that the statement does not explein the age of her grandmother "old" is just drawing a conclusion off nothing, and it does not say that she does not like her at all , thus it is an incorrect statement . So the answer is D.
They are cerebral ventricles
Salt is the Inorganic matter.
Option D.
<h3><u>Explanation:</u></h3>
Organic matters are defined as those compounds of carbon expect the carbonates, bicarbonates, cyanides etc. These compounds were primarily thought to be produced only from the living organisms and were unable to be produced in laboratory. But later they were being produced in laboratory too.
Inorganic compounds are all the compounds except the organic ones.
Here, in the question, we see the compounds -
Protein - it's the polymer of amino acids which contain carbon, and isn't carbonates or bicarbonates, cyanides etc.
Carbohydrates and sugars are also similar to proteins which contain carbon and isn't the exceptions. So they are also the organic compounds.
But salt, commonly table salt is sodium chloride which doesn't contain carbon, so is Inorganic.
Answer:
The correct answer would be - functions.
Explanation:
The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.
In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
Answer: Point mutation is easily reversible, thus non-lethal
Explanation:
Point mutation is caused by exchange of a single nucleotide for another. These change is called
1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)
2) Transversion (when a purine base substitute a pyrimidine base).
However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate
