Answer:
Convergent Evolution
Explanation:
In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
Answer:
Both metaphase and anaphase are processes of cell division.
The metaphase is the phase of cell division during which the meiotic spindle is fully formed. The chromosomes align in the centre of the metaphase plate. Hence, during the metaphase, the chromosomes are present in the centre of the cell.
During the anaphase, the chromosomes are pulled apart towards opposite poles. Hence, during the anaphase, the chromosomes align to opposite poles.
Oryza Sativa is the scientific name for rice
Answer:
8%
Explanation:
DNA is a double-stranded molecule made up of nucleotides: A, T, G, and C. According to Chargaff, A + T + G + C = 100%, where Adenine (A) pairs with Thymine (T) while Guanine (G) pairs with Cytosine (C).
Since G pairs with C and A with T, there must be equal proportions of each nuceleotide pair i.e. A=T, G=C
If C= 42%, G is also 42%
We then have, 42 + 42 + A + T = 100
84 + A + T = 100
A + T = 100 - 84
A + T = 16%
If A and T is collectively 16% and each must contain equal proportion, therefore, A=T = 16/2 = 8%.
Hence, proportion of Adenine and Thymine in that DNA is 8%.
