Answer:

An oil well is usually drilled into a hole in the Earth with a drilling rig.

Explanation:

In summary, a well is created by drilling a hole into the earth with a drilling rig that rotates a drill string with a bit attached. After the hole is drilled to a prescribed depth, sections of steel tubing known as casing are set in the hole (slightly smaller than the borehole) to provide an annuls for cementing. Hope this helps.

A hypertonic solution has:

BaLLatris [955]

A hypertonic solution has:

Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.

<h3>What is hypertonic solution?</h3>

The cell is in a hypertonic solution because it lost water through osmosis and shrunk.
A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.
When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.
An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.

Thus, option "A" is correct.

complete the flow of deoxygenated blood other parts of the body (a)_____(b)_____tricuspid valve (c)______(d)_______capillary bed

NemiM [27]

Answer:

The correct flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)

Explanation:

Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.

From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.

Thus, the flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)
