The correct answer is A. Homologous chromosomes with heterozygous alleles.
If the alleles of genes are different then the scientist is observing for homologous chromosomes with heterozygous alleles.
In each homologous pair there is one chromosome which comes from maternal chromosome and the other one from paternal chromosome.
Homologous chromosomes are not identical but they are similar. Alleles for each homologous chromosome is not same but genes are the same.
Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. ... In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other.

A) In gymnosperms, pollination is the process of transferring pollen from a male cone to a female cone.
Explanation:
In gymnosperms, pollination refers to the process of transferring pollen from the male cone to the female cone. After transfer, such pollen germinates to form the pollen tube and the sperm for fertilizing the egg. This is an essential process to life on Earth. Thanks to pollination, plants are able to reproduce. If the reproduction of a species is not particularly successful, this is at a risk of becoming extinct. Therefore, plants have evolved in ways that ensure the survival and success of their progeny.
