Answer:
The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.
Explanation:
In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.
Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.
In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).
Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

Answer;
The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes oxygen from the atmosphere and produces and releases carbon dioxide to the atmosphere.
Explanation;
Respiration is one of the natural process that adds carbon dioxide to the atmosphere and at the same time remove or decrease the amount of oxygen.
Both plants and animals use respiration process to generate energy in form of ATP that is needed for basic functions such a growth and movement. During this process, nutrients such as glucose are combined with oxygen to yield energy in form of ATP, and also water and carbon dioxide as by-products.
Unlike photosynthesis, which uses carbon dioxide and water to yield nutrients (simple sugars) and oxygen gas, respiration uses oxygen and nutrients, to yield carbon dioxide and water, we can therefore they are antagonistic processes.
Answer:
Chloroplast and mitochondria
Explanation:
Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.
Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.

The correct answer for the question that is being presented above is this one: "Each experiment reveals a different piece of information that is needed to develop the theory." Some theories are developed from repeated testing of a single hypothesis. Cell theory, germ theory, and the theory of evolution all have developed from <span>the testing of multiple related hypotheses.</span><span> </span>
