C. The scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required"
<h3>What is pixel resolution?</h3>
Pixels per inch and pixels per centimeter are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner.
A 7 Tesla scanner, or 7T scanner is preferable to a 3T scanner because the 7 Tesla scanner gives higher pixel resolution when compared to 3 Tesla scanner.
Thus, the scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required".

The difference between the concentration of a substance between two areas is called the concentration gradient. This concentration gradient between a cell and its environment shows a difference resulting in the simplest form of transport called the passive transport. It is the movement of substances from a region of its higher concentration to a region of its lower concentration along with the concentration gradient across a semi permeable membrane.
Passive transport includes diffusion, facilitated diffusion, osmosis and filtration. All these processes are involved in various metabolic activities of the cell. Some of the examples are the movement of water molecules, nutrients, elimination of waste substances, exchange of gases and important life processes like digestion, respiration, excretion, transmission of nerve impulses and others depend on different types of passive transport. On elimination of concentration gradient between a cell and its environment, all the metabolic activities of the cell are inhibited and the cell dies.
<span>Paula, because she has performed the operation very often and now she possesses the ability to perform the operation more strategically and flexibly. Also because she has 35 years of experience should reduce such other negative factors such as complications during procedure.</span>
Answer:
This question is asking to state what is being defined. The term defined in the question is called DIFFUSION
Explanation:
Diffusion is the movement of particles/fluids from a region where they are highly concentrated to the region where they are less in concentration across a space. Diffusion is a form of passive transport i.e does not require energy input to occur. This is because the movement occurs down a concentration gradient.
A concentration gradient i.e difference in concentration occurs when there is an uneven amount/concentration of particles in two regions. Hence, movement occurs naturally to the direction where the particles are less concentrated from where they are more concentrated.
