Answer:
A
Explanation:
Somatic cells are diploid (46 chromosomes)
Gamete cells are haploid ( 23 chromosomes)
The aerodynamic shape and lightness of the blue shark body allow it
to move “elegantly” across the oceans. It exhibits countershading like
many other sharks. The upper part is an indigo blue tone while the
ventral and the sides are white.
It has a long caudal heterocercal fin. The second dorsal fin measures
almost half the size of the first and its pectoral fins are unusually
long compared to other sharks. Its eyes are large, its teeth are
triangular, and it has a conical snout.
It reaches a length ranging from 3.8 to 4 meters and weighs about 240
kilograms. This species presents slight sexual dimorphism since the
female tends to measure little more than 1 meter in comparison with the
male.
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
