Answer:Biotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields
biology the laws and phenomena relating to an organism or group
Biology: The study of living organisms is called biology
Biotechnology: Application of technologies in the field of biology.
What is the difference between biology and biotechnology?Biotechnology is a subfield of biology, which is a science. Biotechnology is the use of biology for human benefit, whereas biology is the study of living things. Biotechnology uses a variety of methods, such as the genetic engineering of bacteria, to produce industrial goods.
The anatomy of living things is what distinguishes biology from biotechnology. The anatomy and physiology of living things are the main topics of biology. Contrarily, biotechnology is concerned with technology. It has nothing to do with the least important aspects of a living thing's anatomy and physiology.

8. Explain why young adults coming into the ER with brain
swelling are often asked about drug use?
Answer:
Over the past several years, the misuse of opioids – ranging from prescription painkillers to black tar heroin – has reached epidemic proportions. In 2015, the Media Research Center reported that drug overdoses had surpassed motor vehicle accident fatalities nationwide for the first time. Since 1999, nearly 200,000 Americans have died from a prescription drug overdose. Heroin use increased in response to advocate and lawmaker efforts to restrict overprescribing, doctor shopping, and opioid sales via online pharmacies. As prescription drug overdoses fell from 2010 to 2015, the number of heroin overdoses tripled.
Opioids are synthetic or semi-synthetic substances originating from the poppy plant. Examples include heroin, Fentanyl, and prescription opioid painkillers, all of which operate in the same fashion, albeit with varying degrees of strength. Synthetic opioids are among the most dangerous and addictive. The synthetic opioid Fentanyl, for example, is 25 to 50 times more potent than heroin, which is a semi-synthetic substance.
The National Institute on Drug Abuse explains, “[Opioids] act by attaching to specific proteins called opioid receptors, which are found on nerve cells in the brain, spinal cord, gastrointestinal tract, and other organs in the body.” When substances attach to these receptors, they change how the brain perceives pain and instead produce feelings of euphoria. They also slow essential body functions, such as heart rate and breathing.

Which of the following is(are) non-technological ways of improving air quality?
a. using public transportation
b. building wind turbines
c. turning lights off when leaving a room
d. both a and c
Using public transportation and turning lights off when leaving a room are both non-technological ways of improving air quality. Therefore, (A) and (C) are correct.
What is air quality?An air quality index is a tool that is used by government agencies to communicate with the general public about the current level of air pollution as well as the level of air pollution that is expected to occur in the near future.
The Clean Air Act regulates a number of key air pollutants, including ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The AQI is determined based on these four pollutants. The Environmental Protection Agency (EPA) has developed national air quality standards to safeguard the general population from each of these contaminants.
We can improve the quality of the air by:
Try to cut down on the amount of times you drive your vehicle.Use of fireplaces and wood stoves should be cut back or eliminated entirely.Avoid burning anything, including leaves, rubbish, or other objects, on fire.Try to avoid using lawn and garden equipment that is powered by gas.Learn more about AQI, here;

Whats the difference between bacteria cells, and blood cells?
Answer:
recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.
While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must do, especially the actual experiment part. You must also list the "controlled variables", the "independent variable", and the "dependent variable
Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.

What is a rule for making a neutral atom which has no charge?
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution (i.E., distilled water). Would the blood cell get bigger or smaller? Why? In your explanation, you must tell me which area has the hypotonic solution (inside the blood cell or outside the blood cell), which area has the hypertonic solution (inside the blood cell or outside the blood cell), and which direction the water would be moving (into the cell or out of the cell).
Answer and explanation:
If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.
The cell contains a more concentrated solution than the solution in the container. The difference in concentration would produce an osmotic gradient that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.
In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

Homologous chromosomes are chromosomes that are the same? true or false
Answer:
False
Explanation:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.
