People who work close to aircraft at an airport are given protective headsets to wear to help prevent hearing damage, but other people who work in places that are loud enough to damage their hearing, such as nightclubs, get no protection at all. Is this reasonable? What could be done about it?
Answer:
People who work on aircraft need the headsets to talk to the plane and other workers on it. People who work in nightclubs are probably used to the noise tho.
During the Precambrian, Earth's first atmosphere is theorized to have been composed of a poisonous mixture of helium and hydrogen gases. When Earth's crust began to cool, the makeup of the atmosphere changed.
Answer:
Yes.
Explanation:
Yes, early Earth's atmosphere was formed from the poisonous mixture of helium and hydrogen gases. But with the passage of time when Earth's crust began to cool, the composition of the atmosphere changed and carbondioxide and water concentration in the atmosphere increases due to carbondioxide gas emission from the volcanoes and evaporation of water from water bodies present on the surface of earth.

2. Explain how to focus a microscope using the high power lens. Include any safety issues you need to be
aware of
Answer.
Type your answer her to focus a microscope using the high-power lens you have to use the focus adjustment
knob but be careful because if you crank down too hard you can damage the microscope and the slide
Is my answer right
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.
Hope it helps!

Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is Choose... . Byproducts of fermentation may include Choose... or Choose... . Fermentation yields Choose... ATP than the electron transport chain.
Answer:
Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is low or absent. Byproducts of fermentation may include lactic acid or ethanol. Fermentation yields less ATP than the electron transport chain.
Explanation:
Fermentation is a chemical reaction that occurs under anaerobic or low-oxygen condition whereby the NADH produced during glycolysis is oxidized to NAD⁺ with the production of lactic acid as well as other products such as ethanol.
Since oxygen is lacking, pyruvate and NADH produced in glycolysis cannot be oxidized. In order to produce energy in the form of ATP for the cells and tissues,the NAD⁺ is regenerated from NADH by the reduction of pyruvate to lactic acid by the enzyme lactate dehydrogenase. In some other organisms such as yeast and microorganisms, pyruvate is converted to ethanol and carbon dioxide.
The net production of ATP in fermentation process is 2 molecules of ATp much lesser than that produced in aerobic respiration.

Compare the two nuclei that form as a result of mitosis. AWARDING 50 POINTS, I WILL REPORT ANSWERS THAT ARE USING ME FOR POINTS.
Answer:
Both nuclei has similar shape and size.
Explanation:
The two nuclei are similar in size and appearance which is formed as a result of mitosis. Mitosis is a type of cell division in which a parent cell divides and produces two daughter cells that are identical to each other in size and shape. When the daughter cells formed the parent nuclei is divided and half part of nucleus is present in each daughter cell.

If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)
Then in the speech bubble next to the picture of Chargaff- talk about his rule.
What does the rule mean?
What does the rule explain?
How is the rule demonstrated?
Lastly, finding percents. What percent of the pairs has Adenine in them?
For example:
If I look at this pairing below
A →T
T→ A
G →C
C→ G
50% of the pairs include Adenine.
Hope I helped! Comment if you have questions about my answer :)
Answer:
If the sequence of nitrogenous bases of a DNA strand is ATCTAGGCCG, the complementary strand would be TAGATCCGGC, with a percentage of guanine 30%, cytosine 30%, adenine 20% and thymine 20%, according to Chargaff's rule.
Explanation:
DNA is made up of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one strand are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=T Guanine is complemented with Cytosine G≡CThe image shows a DNA chain whose chain is complementary:
DNA Strand given Complementary Strand
Adenine Thymine
Thymine Adenine
Cytosine Guanine
Thymine Adenine
Adenine Thymine
Guanine Cytosine
Guanine Cytosine
Cytosine Guanine
Cytosine Guanine
Guanine Cytosine
Therefore, in a DNA molecule there is as much adenine as thymine, and an equal amount of cytosine and guanine. In this example there are 4 molecules of adenine, 4 molecules of thymine, 6 guanines and 6 cytosines.
The proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff was able to establish that in a DNA molecule the ratio of purine:pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
Guanine 30%
Cytosine 30%
Adenine 20%
Thymine 20%
Total ..... 100%
wild animal attack is which type of disaster
(a) biological
(b) geological
please help me
Wild animal attacks should qualify as biological disasters rather than geological disasters.
Disasters generally refer to accidents that happen rather suddenly and result in widespread damages or loss of lives
Biological disasters are disasters whose causes have biological origins such as plants, animals, humans, and microbes.Geographical disasters are caused by natural geographical events such as landslides, cyclones, hurricanes, volcanic eruptions, and so on.Wild animals are biological organisms, hence, an attack from them would be a biological disaster.

Which one of the following factors does NOT affect Earth’s climate?
A. Ocean Currents
B. Energy from the Sun
C. Elevation
D. Soil Composition
Answer:
D
Explanation:
its just not any other one
Our soil cleans our water, feeds our trees and crops with vital nutrients, and controls numerous significant greenhouse gases in addition to helping to maintain the Earth's temperature. Thus option D is correct.
What is the soil impact on Earth climate?On a smaller scale, soil can also affect climate. More so than drier, looser soils, wetter or denser soils hold heat and stabilize the environment from temperature variations.
In deserts, the temperature can rise by more than 60 °F in a single day. The largest repository for terrestrial carbon is healthy soil. In the carbon cycle, soils are essential because they absorb carbon from decaying plant tissue.
By storing carbon (carbon sequestration) and reducing greenhouse gas emissions in the atmosphere, soils can be effectively managed to mitigate climate change.
Therefore, soil composition factors does NOT alter Earth’s climate.

3. Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?
Answer:
Since the cell is dividing it needs two copies of it's DNA. One is kept by the parent cell and the other is passed to the daughter cell..... So this process of duplicating DNA is very important, because the daugher DNA cell will likley die.

What is the relationship between population number and caring capacity in a stable population
Answer:
As resources are depleted, population growth rate slows and eventually stops: This is known as logistic growth. The population size at which growth stops is generally called the carrying capacity (K), which is the number of individuals of a particular population that the environment can support
