Answer:
The correct answer is 1: In Waters´ method, the head is rested on the extended chin.
Explanation:
The parietoacanthial projection (Waters' method) is a widely used radiography method that demonstrates if there are any facial bone fractures, inflammation, or foreign body in the patient skull.
The patient must be in an erect position or prone. They must rest their head on the tip of the <u>extended chin</u> against the table surface. The neck must be hyperextended so that the orbitomeatal line (OML) forms a 37-degrees angle with the plane of the image receptor (IR). This is<u> not perpendicular to IR</u>, as <u>perpendicular means</u> that a <u>90-degree angle</u> must be formed. The mentomeatal line (MML) must be perpendicular to the image receptor plane. Finally, the midsagittal plane must be perpendicular to the plane of the image receptor.
The answer would be:
Passive transport
Active transport
Why?
There are two ways molecules can move across membranes within the cell. What makes the two different is the use of energy.
PASSIVE transport is the movement of molecules DOWN the concentration gradient. The molecules move from areas of higher concentration to lower concentration. This does nor require energy. Comparing it to the scenario, the child starts from a higher area and ends at a lower area. Going down a slide does not take energy. The child simply goes down it.
When you talk about the child going UP a slide, think ACTIVE transport. Unlike passive transport, active transport requires energy, because the molecules move AGAINST the concentration gradient. The movement of molecules in this type of transport is the opposite, it goes from lower areas of concentration to higher areas of concentration.
Hopefully, this has been educational for you and was able to help you understand the difference between the two.
These are called invasive species (like the Giant African Snails in Galapagos for example.)
