Answer:
True
Explanation:
Exon is a part of gene that encodes for final mature RNA after processing. In the process of RNA splicing, introns are removed and exons are retained and joined to produce mature mRNA.
They have protein coding sequence and also UTR ( Untranslated Region ) which plays a role in translation termination and post transcriptional gene expression. Human genome has only 1.1% exon and is majorly composed of introns and intergenic DNA.
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor.
Cellular respiration is the process that cells use to break down food to use as an energy. Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only two ATP molecules.
