<span>A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly.
So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1
Hope this helps!</span>

Answer:
The result of non-disjunction of chromosomes during meiosis, producing three copies of the chromosome in the embryos -instead of two- is called trisomy.
Explanation:
With reference to genetics, a cell is diploid because it has an even number of chromosomes, distributed in pairs - each of which is contributed by a parent - and responds to the formula 2n.
In trisomy, non-disjunction during meiosis of the homologous chromosomes causes an overloadin the corresponding gamete, which during fertilization will originate an embryo whose formula is 2n+1.
Trisomias are considered mutations, which can physically and functionally affect an individual, or even make an embryo not viable. <u>This defect can occur in both autosomes and sex chromosomes</u>.
A very common example of this mutation corresponds to the trisomy of chromosm 21, known as Down syndrome.

Answer:
A cell carries out it's normal functions during mitosis
Answer:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
