Answer:
They are secreted from pancreatic cell through exocytosis.
Explanation:
Beta cells of the pancreas are responsible for the synthesis and release of insulin in the blood. Insulin is released in the blood when the blood glucose level reaches above the normal blood glucose level.
Once the beta cells are insulated the insulin is released from the cell by the process of exocytosis and reaches to blood capillaries of islets. Insulin is made up of A and B chain when released in the blood but in proinsulin, a C chain is also present which is released in mature insulin.
Therefore exocytosis is responsible for releasing insulin from the Beta-cell of the pancreas.
Deletion mutations in the type of frameshift mutation. thus option D is the correct option.
<h3>
What do you mean by frameshift mutation?</h3>
A frameshift mutation is an insertion or deletion that modifies the protein's complete reading frame and has the potential to be extremely harmful.
Frameshift mutations, which alter the ribosome reading frame and cause premature translation termination at a new nonsense or chain termination codon, are deletions or additions of 1, 2, or 4 nucleotides (TAA, TAG, and TGA).

Answer:
b. mRNA from DNA
Explanation:
Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.
The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.
The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.
<span>The presence of light and enzymes within the plant's chloroplasts act as the catalysts for the light-dependent reaction and begin the process by splitting the water molecules into electrons, protons and oxygen. Hope this answers the question. Have a nice day.</span>
The nuclei is combined to form a heavier nucleus, releasing energy
