Answer:
peptide and protein hormone
Explanation:
Peptide and protein hormones are composed of amino acids with latter being longer in length. They are synthesized in rough endoplasmic reticulum where they undergo various modifications like N terminal signal sequence removal and glycosylation to form prohormones. These prohormones are sent to golgi apparatus where they are packaged in secretory vesicles. In response to a stimulus the appropriate vesicle is released via exocytosis.
They can show regulated secretion where the hormone is stored in vesicles for a long time and then released in large amount in bursts for a proper stimulus. Sometimes they also show constitutive secretion where they are released slowly and steadily by the vesicles.
Fitness is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment.
I hope this helps, if you need any more help on science please ask me, if it is right please give me brainest if not tell me that it wrong
Have a nice day!
