Conceptualize: The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground.

Analyze: Alexander graham bell invented the first crude metal detector in 1881. As president James Garfield lay dying of an assassin's bullet in 1881, hurriedly invented a metal detector in unsuccessful attempt to locate the fatal slug.

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.

5 factors that affect weather: geographic location/latitude altitude/height above sea level, ocean currents/large lakes, winds,t
Igoryamba

The statement is - True.

The five main factors that determine the weather at a certain place are the:

- geographic location/latitude

It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.

- altitude/height above sea level

The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.

- ocean currents/large lakes

The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.

- winds

The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.

- topography

Determines how much a place is exposed to the sunlight and the movement of the air masses.
