Answer:
Fins are limbs.
Explanation:
A limb is considered an appendage of any body. Since a fin is an appendage of an animal body, it is indeed a limb.
Answer:
Phytoplanktons are producers
Squid are secondary consumers
Leopard seals are quaternary consumer
Explanation:
Phytoplanktons are producers because this are small plants that produce their own food by the process know as photosynthesis
Consumers are organisms that depends on plants for survival. They cannot produce their own food like plants. Fish are primary consumers because they eat plants. When Squids eat fish , squid is considered a secondary consumer because they eat the primary consumer.
Leopard seals are quaternary consumer because they are at the top of the food chain or the tertiary consumer. They eat the primary and the secondary consumer
Humans store excess polysaccharides in the form of glycogen.
Polysaccharides are carbohydrates. They are generally used to generate energy in the form of ATP for the body's metabolic activities.
Carbohydrates are broken down during respiration to generate energy. Excess carbohydrates are generally converted to glycogen through the actions of an enzyme in the liver.
Glycogens are converted back to simpler carbohydrates when there is inadequate carbohydrate in the body.

The exons of the pre -mRNA contain the protein -coding regions.
Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.
The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.
RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins. These SnRNPs make the spliceosome, which catalyzes the process of splicing.
After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.

Answer:
plant propagation
Explanation:
Plant propagation is the process which grows new plants from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds.
