Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.
Answer:
Explanation:
In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.
In the virion of a naked virus, only nucleic acid and protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.
Although virus particles are metabolically inert, one or more key enzymes are present within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.
Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.
The attachment of a virion to a host cell is a highly specific process. Recognition proteins on the virus recognize specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

How do meteorologists indicate different types of weather fronts on a weather map?
Answer:
A stationary front is depicted by an alternating red and blue line with a triangle on the blue portion and half-moon on the opposite side of the red portion of the line. A cold front (or warm front) that stops moving becomes a stationary front.

Explain the digestion process of a complex carbohydrate by arranging the statements in the order that they occur.
Answer: The question is incomplete because the options are not given, here are the options from another websites.
A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.
B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides.
C. You take a bite and to chew the complex carbohydrate into smaller pieces.
D.Amylase is deactivated by the low pH in the stomach.
E.. Monosaccharides are absorbed through the intestinal wad.
The correct order are,
C. You take a bite and to chew the complex carbohydrate into smaller pieces.
A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.
D.Amylase is deactivated by the low pH in the stomach.
B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides
.E. Monosaccharides are absorbed through the intestinal wad
Explanation:
Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c
Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.
Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.

Explanation:
Damage to the highlighted region of the spinal cord results in ________ of the skeletal muscles served by that particular region.
Answer:
Non-functioning
Explanation:
Non-functioning of skeletal muscles occurs when the spinal cord region is damaged because spinal cord is responsible for sending information in the form of signals. The spinal cord has a network of fiber started from the brain and distributed to all the body is known as neurons. These neurons are responsible for sending instructions to the muscles from brain. If they are damaged, the body parts unable to move and can't perform their particular function.

Explanation:
I took the test.
Why was it important to drop the ball from the same height three times? Why were the numbers
slightly different?
Answer:
It is important to do this to test your theory multiple times, so that you can see what effect the drop has on it when doing this multiple times. The numbers were slightly different because the recordings will not always be the same.

Explanation:
Consider what would happen to a diploid plant when genes are destroyed by a mutation.
How many genes would have to be destroyed in a diploid plant for one trait to be lost?
Answer:
Two, usually
Explanation:
A diploid plant has two copies (alleles) of every gene. If one copy of the gene is destroyed by a mutation, the plant will likely be okay with its other copy, and the trait will still be expressed.
However, some traits require both copies of the gene to be expressed. For example, if one gene is destroyed that means only half the amount of the gene product is produced. If that is not enough protein for the trait to be expressed, then the trait will be lost.
Which method of determining salinity is least likely to be used by current oceanographers?
A. Determining salinity based on measurements of the chloride ion
B. Determining salinity based on refraction of light
C. Determining salinity based on satellite observations
D. Determining salinity based on electrical conductivity of seawater using a CTD
Answer:
D
tell me if I am wrong please
Answer:
Refraction OF LIGHT
Explanation:
Salinity can be measured in various ways. Most oceanographers
measure salinity with an instrument called a CTD, named for the three
parameters it measures: conductivity, temperature, and density. To
determine salinity, probes on the CTD record electrical conductivity.
SOURCE OF ANSWER:
Desktop CTD instruments are also available, but when the
highest precision isn't necessary for lab settings, a much simpler tool
called a refractometer is used.
A refractometer measures salinity based on refraction. Refraction is the
bending of light that occurs within a water sample. Only a few drops of
water are placed under the light source of the handheld refractometer.

Using your own words, describe lapse rate.
Answer:
A lapse rate is a rate during which the temperature changes with the peak within the atmosphere.
Explanation:
sorry it took me so long :(
Answer:
The Lapse Rate is the rate that temperature changes with height in the Atmosphere. Lapse rate nomenclature is contrarily connected to the modifying itself. If the lapse rate is positive, the temperature becomes less with height; interchangeably if negative, the temperature becomes more with height.
