Answer:
Messenger RNA on the ribosomes binds amino acids into a peptide chain called a preprohormone. the chain is directed into the ER lumen by a signal sequence of amino acids
-enzymes in the ER chop off the signal sequence, creating an inactive prohormone
-the prohormone passes from the ER through Golgi
-secretory vesicles containing enzymes and prohormone bud off the golgi. the enzymes chop the prohormone into one or more active peptides
-vesicle releases contents by exocytosis
-hormone moves into circulation for transport to its target
<h2>The answer is RNA</h2>
Answer:
Plant cells have chloroplasts because they make their own food. Plant cells have a cell wall so that they do not burst when the central vacu
ole fills up with water. ... Each organelle has it's own specific fun
ction to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
Explanation:
Answer:
DNA is the molecule which determines our eye colour, enzyme production and body structure.
Interspecific competition can occur between two different species competing for the same resource in an ecosystem. So for this particular bug population, there may be another insect species that competes for the same food source or another resource, such as material or space for breeding habitat. This can lead to selective pressure, and may result in the different species evolving a more specific diet or inhabiting a niche environment.
