Describe how and why varnishes are used in the restoration process
Answer: A cavity varnish provides a barrier against fluid penetration into the underlying dentin. When applied to dentin, a varnish may reduce postoperative sensitivity and limit migration of corrosion products into dentin, thereby reducing tooth discoloration. RMGI liner/base products seal the tooth and strongly bond to the restoration to reduce the incidence of microleakage between the tooth and the restoration. ... Reduces postoperative sensitivity — RMGI liner/bases offer a strong bond to the tooth, sealing the tooth structure to protect against microleakage.

mutualism - both organisms benefit from their relationshipcommensalism - one organism benefits, while the other doesn't benefit or suffer any harmparasitism - one organism causes harm to the otherIn the given scenario, both the bird and plant benefit from their relationship. The bird gets food, while the plant reproduces more easily. This is why their relationship is an example of mutualism.
Why is the cell like a city?
Answer:
The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.

Explanation:
The plasma membrane found in both prokaryotic and eukaryotic cells is composed of a/an _______, which is semipermeable and controls the flow of molecules into and out of the cell.
Answer:
Phospholipid layer
Explanation:
The plasma or cell membrane is the outer covering of prokaryotic (bacteria) and eukaryotic (plants and animal) cells that provides support to the cytoplasm. The plasma membrane is made up of components like phospholipid layer, proteins, etc. However, the PHOSPHOLIPID LAYER component of the plasma membrane confers its SEMI-PERMEABILITY upon it.
The phospholipid layer consists of a hydrophilic i.e. water-loving region (phosphate head) and hydrophobic i.e. water-fearing region (fatty acid tails) that allows it to selectively control the flow of molecules into and out of the cell.

An early step in the process of carbon fixation combines three molecules of CO2 with three molecules of RuBP to produce three 6-carbon molecules, which are immediately converted to six 3-carbon molecules. These six molecules are phosphorylated and reduced to produce glyceraldehyde 3-phosphate (G3P). What additional events occur to complete the Calvin cycle
Answer:
release of one G3P to make sugars and regeneration of RuBP
Explanation:
The Calvin cycle can be defined as a part of photosynthesis that utilizes the energy stored by light-dependent reactions to produce three-carbon sugars. The first carbohydrate produced by the Calvin cycle is a three-carbon sugar phosphate called glyceraldehyde-3-phosphate (G3P). Subsequently, G3P is used to produce other sugar molecules such as, for example, glucose. The Calvin cycle consists of three steps: 1-carboxylation (by using CO2 in a reaction catalyzed by Rubisco enzyme), 2-reduction of phosphoglycerate (ATP phosphorylation), and 3-regeneration of ribulose-bis-phosphate (RuBP) by using triose phosphates produced in the first two steps.
Assuming that the motion of the object remains the same, at what position will the object be when it had traveled for a total of 6 s?
A. 2 m
B. 0 m
C. 1 m
Answer:
B. 0 m
Explanation:
The graph given is a position - time graphical model of the motion of a body.
The y-axis denotes the position of the body and the x- axis is the time taken.
To solve this problem, since the velocity of the motion is constant and no acceleration, we trace up the point 6s on the x-axis and find the y-axis equivalent.
Completing the graph, the point lies on 0m. At 0m, the object would have traveled for 6s.Answer:B. 0 m

A. function in an acidic environment
B. function in a neutral environment
C. function in a basic environment
D. function in an acidic and basic environment
Answer:
D im pretty sure
Explanation:
Enzymes that work in the stomach must adjust to the unique environment by being able to function in an acidic environment.
Which enzyme would most likely function in the stomach?One or more polypeptide chains of amino acids make up a big protein enzyme molecule. The unique protein folding patterns, which are crucial for enzyme specificity, are determined by the amino acid sequence.
Pepsin and rennin are the two primary enzymes found in gastric juice. While rennin coagulates the soluble milk protein, casein, into an insoluble curd, which is then attacked by pepsin, pepsin breaks down proteins into short polypeptide chains. Pepsin is produced by the chief cells of the stomach as pepsinogen, an inactive zymogen.

Describe the nonspecific antimicrobial effects of mucus, lysozyme, and acidic pH. For each of these substances, list where they are found in the body and how they function in fighting pathogens.
Answer: Non specific defence mechanism are the first lines of general defence that aids in preventing entry and minimising further passage of microbes and foreign materials into the body.
Explanation:
The non specific defence mechanisms protects us against any of enormous range of possible dangers using these methods:
--> defence at body surface
--> phagocytosis
--> natural antimicrobial substances
--> the inflammatory response and
--> immunological surveillance.
MUCUS is a slippery substance which covers the luminal surface of the Lungs. It provides defence at the body surfaces. Incase of any inhaled foreign material through the nose into the lungs, it's usually entrapped by the mucus. It is either coughed up or swallowed.
LYSOZYME: This is a protein with antibacterial properties present in granulocytes, tears and sweat. They are natural antimicrobial substances that destroys the cell walls of bacteria leading to its death.
ACIDIC Ph: The presence of acidic natural substances found in the stomach such as the gastric juice or hydrochloric acid, kills the majority of ingested microbes.
