Answer:

The correct answer will be option-D.

Explanation:

A scientific experiment involving chemicals must be performed with precautions as chemicals can cause serious health problems like carcinogens causing cancer.

The laboratory attire of a lab includes a face mask to cover mouth, a pair of goggle to protect eyes, hand gloves to protect hand and a laboratory coat to protect body and clothes.

Since in the given question, the hand gloves and laboratory coat are missing, therefore, option-D will be considered the most valid answer.

At the site of the rough endoplasmic reticulum, proteins that are destined for secretion are manufactured. Insulin is a protein-
Eva8 [605]

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.

Pachacha [2.7K]

Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

<h3>What are active volcanoes?</h3>

Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.

These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.

Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.

In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
