1 answer:

8 0

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.

Which of the following statements is (are) correct regarding the parietoacanthial projection (Waters' method) of the skull?

Alecsey [184]

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 extended chin 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 not perpendicular to IR, as perpendicular means that a 90-degree angle 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.

After photosynthesis, energy that the coral can use is stored in

katen-ka-za [31]

Answer:

Energy is stored in glucose molecules C6H12O6

Explanation:

Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.

These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.

Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).

Eg. for aerobic respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen → carbon dioxide+ water+ energy
