<h2>Answer:</h2>
The correct answer is option A which is an abnormal male with nondisjunction.
<h3>Explanation:</h3>
The karytope is the complete picture of chromosomes present in a cell of an individual.
It is used to study the chromosome number and abnormalities related with chromosome numbers.
Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.
While chromosomal translocation is the crossing over of genetic material between two chromosomes.
Only chromosomal disjunction can be seen from the karyotype.
Answer:
B.
Explanation:
due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
The ribosomes cause the outer surface of the rough endoplasmic reticulum to appear rough.
Answer:
A, Both cells will replicate their DNA.
Explanation:
During the cell division, cell passes through several phases and divides. Before each phase, the cell has to pass through the checkpoints. At these cell checkpoints, the cell receives the internal and external signals.
When the cell is arrested at G₀ phase, the cell does not divide until it receives a signal to proliferate but when the cell passes the G₁ phase, the cell will divide continuously.
In the given question, if the cells when in their G₀ and G₁ phase receive proliferation signal, the G₀ phase cell will also divide and will replicate it DNA during S phase as G₁ phase cell will do.
Thus, Both the cells will divide their genetic material.
