You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?. . . Condu
DENIUS [597]
If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.

With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.

With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.

With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>

The hormone insulin is a protein produced in the pancreas and then secreted into the blood stream after a meal to increase gluco
GenaCL600 [577]

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.
