Although in many regions of the brain—particularly those that give rise to nuclear cell groups—neurons migrate without the benefit of glial guides, migration along radial glial fibers is always seen in regions where cells are organized into layers, like the cerebral cortex, hippocampus, and cerebellum.
In gymnosperms the seeds are not produced inside the fruit but in angiosperms the seeds are enclosed inside the fruit so they are classified separately.
In general ,Gymnosperms are considered as flowerless plants and are not enclosed inside seeds whereas angiosperms are plants that have flowers. Adding to this, the difference or the basis of classification is on the presence of an ovary.
Hence, gymnosperms and angiosperms both bears seeds, and they are also classified differently . The reason behind this is in case of gymnosperms the seeds are not produced inside the fruit but in case of angiosperms the seeds are enclosed inside the fruit.

Ventilation systems are needed in a <span>multicellular organism to actually obtain oxygen and give out carbon dioxide. Without this ventilation system, it would be very difficult for multicellular organisms to survive. It has been also observed that surface diffusion is not enough for a multicellular organism to breath.</span>
Answer:
option A
Explanation:
In Recombinant DNA technology which involves DNA molecules formed by recombination to bring together genetic material from different sources, producing sequences that would normally not be found in the genome. Some basic steps are to be followed in the formation of your recombinant DNA. The restriction enzyme used in cutting the gene of interest from the pine tree DNA should also be the same used in cutting open the plasmid to make complementary sticky ends. Then integration of the isolated gene of interest into the cut plasmid and then this is treated with ligase to join the cut sticky ends. This construct is then introduced into bacterial cells.
The correct option is HEREDITY.
All living organisms reproduce and give birth to young ones either by mean of asexual reproduction or by mean of sexual reproduction. During the course of reproduction, genetic materials from the parents are transferred to the newly reproduced young ones, so that they possess some of the same characteristics that their parents possess. This process of inheriting traits from parents is present in all living organisms and it is one of the indicators by which living organisms are identified.
