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.

Organisms that complete the final breakdown and recycling of organic materials from
scoundrel [369]

Answer:

decomposers

Explanation:

These are heterotrophic organisms that feed on dead animals and plants, secretions, or discarded parts of living beings, that is, organic matter.

And they break it down into inorganic.

Thus, inorganic substances that can be reused in the process of photosynthesis are returned, recycled, to nature.

Relate plant structure and function to the process of photosynthesis and respiration​
Dmitry [639]

Answer: Photosynthesis is a process through which green plants prepare their food by using carbon dioxide and water as reactants in the presence of sunlight energy. The food produced in the form of carbohydrate. Respiration is the process in which the biochemical oxidation of the food occurs.

Explanation:

The plant structures like leaves are specialized for performing the process of photosynthesis. These leaves have chlorophyll pigment which traps the light energy from sun which is required for splitting the molecules of water in the process of photosynthesis. Respiration occurs through stomata in leaves. But it also occurs in stems through lenticels and in specialized roots called pneumatophores via tiny pores.

The expression of a gene to form a polypeptide occurs in two major steps. What are these two steps in their correct chronologica
Katen [24]

two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)

The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.

It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.

  • The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
  • The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.
