Explain why mirages occur.

Answers

Answer 1

Answer:

Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.

Many people have strong feelings about genetically modified foods. There are benefits and concerns. What do you think? Do the benefits outweigh the concerns, and genetically modified foods should be available? Or, the concerns outweigh the benefits and genetically modified foods should not be used?

Answers

Answer:

Genetically modified (GM) foods contain at least one ingredient coming from a plant with an altered genetic composition.16 Genetic modification, also known as genetic engineering, often introduces new, desirable characteristics to plants, such as greater resistance to pests. Many U.S. crops are grown using genetically engineered seeds, including a large share of the soybean, corn, cotton and canola crop. As a result, the majority of processed foods in the U.S. contain at least one genetically modified ingredient.About one-in-six (16%) Americans care a great deal about the issue of GM foods. These more deeply concerned Americans predominantly believe GM foods pose health risks. A majority of this group also believe GM foods are very likely to bring problems for the environment along with health problems for the population as a whole.A number of observers have suggested that Americans’ limited familiarity with genetically modified foods suggests that people’s opinions about GM are “soft” and, therefore, more likely to change over time and, potentially, to be sensitive to differences in survey question wording.

Explanation:

Genetically modified foods are made in such a way that their less effective or diseased genes are eliminated and beneficial genes are overproduced.

What do you mean by GM crops?

Genetically modified crops may be defined as those crops or foods which are derived in such a way that their genetic material does not occur naturally.

The concerns of GM foods outweigh the benefits and genetically modified foods should not be used. Some of the reasons are given below:

GM foods promote allergic reactions which affect the health of the individual.It may also contribute to antibiotic resistance. They are dangerous to insects as they have insect-resistant genes. GM technique lowers the diversity among crops. It may harm the environment to a larger extent.

Therefore, the concerns of GM foods outweigh the benefits and genetically modified foods should not be used.

waves?
11 Calculate What is the speed of these waves?
a
12 Solve If you were sitting in a boat as these
waves passed by, how many seconds would
pass between wave crests?

Answers

Answer to No 10.
Wavelength(m) = Velocity(m/s) divide by frequency of the wavelength(Hz).
i.e 6 divide by 0.5 = 12m
Therefore wavelength = 12m

Answer to No 11.
Speed of wave or wave speed = wavelength x frequency of the Wavelength
New Wavelength gotten is = 12
Frequency = 0.5hz
Therefor Wavespeed= 12 x 0.5 = 6nm/s

Answer to No 12
They want you to find the new wave frequency to be used as wave crest and wave frequency = wave speed divide by wavelength
F= 6 divide by 12
F = 1/2 or 0.5sec
There 0.5sec would pass between wave crest

The frequency of a wave is the number of waves that pass a point in a given amount of time. It is measured in hertz (Hz), which is equal to one wave per second. The wavelength of the waves is 12 meters, the speed of the waves is 6 meters per second, and the time between wave crests is 2 seconds.

The wavelength of a wave is the distance between two consecutive wave crests or troughs. It is measured in meters. The speed of a wave is the distance that it travels in a given amount of time. It is measured in meters per second.

Frequency = 0.5 Hz

Wavelength = 6 meters

Wavelength = Speed / Frequency

Wavelength = 6 meters / 0.5 Hz

Wavelength = 12 meters

Speed:

Speed = Wavelength × Frequency

Speed = 12 meters * 0.5 Hz

Speed = 6 meters per second

The time between wave crests:

Time between wave crests = 1 / Frequency

Time between wave crests = 1 / 0.5 Hz

The time between wave crests = 2 seconds

Therefore, the wavelength of the waves is 12 meters, the speed of the waves is 6 meters per second, and the time between wave crests is 2 seconds.

drug-resistance gene

Answers

Answer:

Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.

Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

Antibiotics fight germs (bacteria and fungi). But germs fight back and find new ways to survive. Their defense strategies are called resistance mechanisms. Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.
