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.
Humans deplete the most resources when
Answer:
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

Which of these is a condition where the endometrial lining that is normally supposed to only be inside the uterus, ends up outside the uterus (for instance, in the pelvic cavity) and causes extreme pain during menstruation? This condition affects up to 1 in 4 women.
Answer:
Endometriosis is called the pathology
Explanation:
Endometriosis is a pathology where fibroblasts or connective tissue cells proliferate outside the fallopian tubes in the abdomen, close to the intestine, and adjacent to the ovaries, by proliferating and reducing the space between the organs, the pressure of the terminals increases nervous and during menstruation it hurts.
They are benign proliferative cell foci.
How can we reduce the negative impacts of human activity on climate
change?
Answer:
having fewer humans on earth would solve this
Explanation:
Answer:
Improving the energy efficiency of buildings to reduce emissions from heating/cooling.
Planting forests and tree to remove excess carbon dioxide from our atmosphere.
Reducing fuel emissions associated with motor vehicles.
Explanation:
Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
Describe the energy-releasing reaction shown in figure 1
idkeubeekenebekeenne
The energy-releasing reaction shown is the reaction of phosphorylation of fructose-6-phosphate to fructose-1, 6-bisphosphate.
Phosphorylation simply means the biochemical process that has to do with the addition of phosphate to an organic compound.
In this case, there's a reaction with fructose-6-phosphate to fructose-1, 6-bisphosphate.
Also, the ATP molecules have three high-energy phosphate groups which are vital for the transfer of one of its phosphate groups to fructose-6-phosphate and also provide energy to carry out the reaction.

The number of waves passing the observer per second is:
- the wavelength
- the amplitude
-the frequency
- the period
Answer:
frequency
Explanation:
comment if im wrong
The number of waves passing the observer per second is the frequency. Hence, the correct option is C.
What is frequency?Frequency refers to the number of waves that pass from a fixed point in unit time. It is a measure of the rate of repetition of a periodic phenomenon such as vibration or a wave.
It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. The more cycles that occur per second, the higher the frequency of the system is.
For example-The human heart beats at a frequency of 68 beats per minute.
In general, frequency is a very important concept in many fields including physics, engineering, music and the natural sciences, and it is used to describe and analyze a wide range of periodic phenomenon.
Therefore, the correct option is C i.e., frequency.

Does the absence of one organism or two in the food chain change or affect the producer or consumer relationship?
Answer:
yes
Explanation:
Pressure and depth share a linear relationship. For every _____ meters that the depth of seawater increases, the pressure increases by another atmosphere or bar.
A. 10
B. 25
C. 100
D. 1000
For every 10 meters that the depth of seawater increases, the pressure increases by another atmosphere or bar. So, the correct option is (A).
What is Pressure?Pressure is defined as the force that is exerted per unit area of an object perpendicular to the surface on which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Several units are used to express pressure.
It can be expressed as:
[tex]P = \frac{F}{A}[/tex]
Where, P = pressure
F = force
A = area
In water, the greater the depth, the greater will be the pressure, so for every 10 m increase in depth, the water pressure increases by about 100 kilopascals (kPa). The SI unit of pressure is pascal (represented as Pa) which is equal to one newton per square metre [tex](N/m^2 ) or (kg m^-^1s^-^2).[/tex]
Thus, for every 10 meters that the depth of seawater increases, the pressure increases by another atmosphere or bar. So, the correct option is (A).

the process by which green plants and some other organisms use sunlight to synthesize get nutrients from carbon dioxide and water.
Explanation:
hopes this helped :)
Photosynthesis is defined as the processes that bring about the manufacturing of food by green plants.
Food is complex energy-rich organic matter which living organisms feed on to obtain nutrients, substances necessary for life. Green plants which are known as autotrophs has the ability to produce their own food through the process of photosynthesis.
The main features of photosynthesis include:
It takes place in the chloroplasts of plants, in the presence of sunlight.The energy needed for the process is gotten from sunlight which is absorbed by chlorophyll found in the chloroplasts.The raw materials used are low-energy containing inorganic compounds, example: carbon dioxide and water.The final products are high-energy containing sugars. oxygen is given off as a waste product.Learn more here:
