marine mammals, which are air breathers, can swim for hours at the surface of the water with minimal negative affect. If they di

Drag each label to the correct location.
cluponka [151]

Answer:

The geosphere or geosphere is the internal and solid part of the Earth that is composed of three concentric layers called crust, mantle and nucleus. Without the geosphere, human beings cannot live on the planet, since there is no solid ground. In the Earth's geosphere are rocks, minerals, magma, sand and mountains.

This layer interacts with the other layers of the earth system, including the atmosphere, hydrosphere and biosphere, and is in a state of constant motion; Sedimentary, igneous and metamorphic rocks within the Earth's geosphere undergo continuous recycling.

It is said that the Earth formed about 4.6 billion years ago from the collision of meteoric debris that created the solar system. Due to the constant collisions during its formation, the initial temperature of the planet was extremely high; It was all molten matter.

But during the next phase of Earth's formation there was a cooling, and with it, the differentiation of the Earth's layers. Dense materials sank in the center, forming a core rich in iron and nickel. The lighter magma rose to the surface, forming the thickest layer of the Earth called the mantle.

Eventually, the outermost magma cooled to form the thin layer we call Earth's crust.

Bacteria multiply by division. One bacterium becomes two. Then two divide into four, the four divide into eight, and so on. For
Leto [7]

Answer:

1) By 11:30pm

2) Shortly before midnight (few minutes to 12:00am)

Explanation:

Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:

I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour

II) Split 1 hour into two (60minutes makes 1 hour)

I hour/2 = 30 minutes

Definitely, the bottle will be half filled by 11:30pm

2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out

Why did classical astronomers conclude the heavens were made up of sphere?
Natalija [7]
The classical astronomers concluded that heavens were made up of a sphere, because heavens were thought to be perfect and spheres (circles) are a perfect shape. It was Plato who argued that geometrical figures were spheres and everyone agreed to him. It was also believed that the perfect motion of spheres was a uniform circular rotation.

Describe how the action potential is regenerated by local ion flux
zhenek [66]
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
