Answer:
Option C is correct. The flow chart best shows the relationship between the cell structures is:
DNA → gene → chromosome → nucleus
Explanation:
DNA can be described as the material of inheritance.
A gene can be described as the basic unit of inheritance. It is made up of segments of DNA.
Chromosomes can be described as thread-like structures which are made up of different genes.
The nucleus is the site where chromosomes are placed. The nucleus is found in every eukaryotic organism.
Hence, the correct order for these cell structures is illustrated in option C.
Position and mass product
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.
Answer: Aristotle and Ptolemy had both assumed each planet is attached to a single sphere, but geometers and astronomers could employ a number of such spheres to generate the observed motions of the planets.

Answer:
The correct option is <em>B. Cholesterol is non-polar.</em>
Explanation:
Cholesterol is a non- polar substance and due to this property it is an active part of the cell membrane. Cholesterol molecules help to maintain the stability of a cell. When the temperatures are high, cholesterol stops the cell membrane from crystallization. When the temperatures are low, cholesterol reduces the packaging of molecules of phospholipids. As a result, fluid phase is archived by the cell membrane.
