What is an electromagnetic wave? Use the model to describe the characteristics of these waves.
Electromagnetic radiation contains waves of the electromagnetic field, which propagate through space and carry radiant energy. The radiations coming from the sun are electromagnetic waves.
What are electromagnetic radiations?Electromagnetic radiation possesses waves of the electromagnetic field, which travel via space and carry radiant energy. These waves include microwaves, radiowaves, infrared rays, visible light, UV rays, X- rays, and gamma rays.
Electromagnetic waves oscillate with the electric field and magnetic fields. Electromagnetic waves exhibit periodic changes in the electric field or magnetic field.
Depending on the periodic change in the waves that take place and the power produced in the waves, different wavelengths or frequencies of the electromagnetic spectrum are produced.
The effects of this radiation on chemical compounds and biological organisms are related to the power of the radiation and its frequency.
In order of increasing frequency and decreasing wavelength, electromagnetic waves are organized in the electromagnetic spectrum.

This passage describes the xeroderma pigmentosum trait in humans:
Xeroderma pigmentosum is a condition that causes skin to be easily damaged
by sunlight. Humans with xeroderma pigmentosum avoid exposure to sunlight by
wearing protective clothing, using sunscreen, and not going outside during the
day.
In a group of humans, some individuals have xeroderma pigmentosum and others do not. In
this group, the gene for the xeroderma pigmentosum trait has two alleles. The allele E is for
not having xeroderma pigmentosum, and the allele e is for having xeroderma pigmentosum.
Hunter, a human from this group, does not have xeroderma pigmentosum. Hunter has two
alleles for not having xeroderma pigmentosum.
Based on this information, what is Hunter's genotype for the xeroderma pigmentosum gene?
Ee
EE
not having xeroderma pigmentosum
having xeroderma pigmentosum
Answer:
Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight. This condition mostly affects the eyes and areas of skin exposed to the sun. Some affected individuals also have problems involving the nervous system.
The signs of xeroderma pigmentosum usually appear in infancy or early childhood. Many affected children develop a severe sunburn after spending just a few minutes in the sun. The sunburn causes redness and blistering that can last for weeks. Other affected children do not get sunburned with minimal sun exposure, but instead tan normally. By age 2, almost all children with xeroderma pigmentosum develop freckling of the skin in sun-exposed areas (such as the face, arms, and lips); this type of freckling rarely occurs in young children without the disorder. In affected individuals, exposure to sunlight often causes dry skin (xeroderma) and changes in skin coloring (pigmentation). This combination of features gives the condition its name, xeroderma pigmentosum.
People with xeroderma pigmentosum have a greatly increased risk of developing skin cancer. Without sun protection, about half of children with this condition develop their first skin cancer by age 10. Most people with xeroderma pigmentosum develop multiple skin cancers during their lifetime. These cancers occur most often on the face, lips, and eyelids. Cancer can also develop on the scalp, in the eyes, and on the tip of the tongue. Studies suggest that people with xeroderma pigmentosum may also have an increased risk of other types of cancer, including brain tumors. Additionally, affected individuals who smoke cigarettes have a significantly increased risk of lung cancer.
The eyes of people with xeroderma pigmentosum may be painfully sensitive to UV rays from the sun. If the eyes are not protected from the sun, they may become bloodshot and irritated, and the clear front covering of the eyes (the cornea) may become cloudy. In some people, the eyelashes fall out and the eyelids may be thin and turn abnormally inward or outward. In addition to an increased risk of eye cancer, xeroderma pigmentosum is associated with noncancerous growths on the eye. Many of these eye abnormalities can impair vision.
About 30 percent of people with xeroderma pigmentosum develop progressive neurological abnormalities in addition to problems involving the skin and eyes. These abnormalities can include hearing loss, poor coordination, difficulty walking, movement problems, loss of intellectual function, difficulty swallowing and talking, and seizures. When these neurological problems occur, they tend to worsen with time.
Researchers have identified at least eight inherited forms of xeroderma pigmentosum: complementation group A (XP-A) through complementation group G (XP-G) plus a variant type (XP-V). The types are distinguished by their genetic cause. All of the types increase skin cancer risk, although some are more likely than others to be associated with neurological abnormalities.

An object is floating in the water, as shown in the picture below.
Describe the movement of the floating object as a wave passes by, and explain why the object is not carried forward with each wave.
Your answer should include at least two complete sentences.
Answer:
Balance Weight
Explanation:
The object has vertical weight with a floating device in it. When the waves hit the object in the water, they will go upward and then downward but stay in the original spot. This happens because the object uses the electromagnetic energy from the waves to not move with it.
Yellowstone volcano
If you found out that Yellowstone was erupting, who would you want to find first?
Where do you think you would go to find safety?
If you survived, what do you think the World would be like after it was over?
How long would it be that way?
Can you think of another time in our Earth's history where something like this happened and affected a society of people?
If the Yellowstone volcano erupts I hope to find my family and I would stay at home. I believe that after this event, the sky would be opaque for a long time due to ash, something similar to the mass extinction of dinosaurs.
What is the Yellowstone volcano?The Yellowstone supervolcano is a volcanic caldera located in Yellowstone National Park (Wyoming) in the United States. The caldera measures approximately 55 × 72 km.
This volcano was formed during the last of the three super-eruptions that occurred over the last 2.1 million years.
What would happen if this supervolcano erupted?If the Yellowstone supervolcano were to erupt, it would produce a massive ash shower that would cover the entire United States for decades.
On the other hand, the climatological conditions would be modified, given the magnitude of the geological formation that rests, still active, below the National Park.

A bat wing is more similar in anatomical structure to a cat forelimb than to a bird wing. Answer the following questions about these structures.
A.Which pairs are homologous structures?
B.Which pairs are analogous structures?
C.Based on this, do you think a bat is more closely related to a cat or a bird? Explain your answer.
Answer:
The answer is homologous structures .
Explanation:
All the fore limbs that you mention are made up of same sets of bones. These vertebrates are all mammals, hence evolved from a common ancestral stock. So they all inherited a basic anatomical structure which later became adapted for different habits and habitats. These are regarded as homologous structures: anatomically similar, functionally different

Pls help me with my lab report for chemistry ANSWER QUICKLY
Lab Report: Thermal Energy Transfer
what do u need help with u pls respond quickly
Different masses will change its temperature at different rates when exposed to the same amount of thermal energy because the amount of mass affects an object’s ability to absorb thermal energy. Different materials will change the temperature at different rates when exposed to the same amount of thermal energy because each substance has its own specific heat.
Scientists conducted an experiment to show whether the ability to see an object affects a person's idea of the mass of the object. They used the following procedure: Obtain two cardboard boxes of different sizes. Place rocks in each box so that both boxes have the same mass. Close each box and tie a string to it so that participants lift each box using the string. Blindfold half of the participants in the experiment. Ask participants to lift each box using the string and report which one they think has more mass. Record results. The table shows the results of the experiment
Answer: Visual information makes them think the larger box has more mass.

In one or two sentences, explain what the main impact tsunamis cause on humans .why is it difficult to avoid a tsunamis
Answer:
Many people die from tsunamis because of drowning, and injuries such as broken limbs and head injuries can be caused. It's difficult to avoid tsunamis because they're hard to predict.
1 impact of tsunamis
A major impact of tsunamies on Humans is the damage that they do to everything. They don't just do damage to Property and Structures, they do damage to people's lives, and ecosystems in the water and also ecosystems near the water. The water has such a high speed and force that it can tear down buildings as you must have seen in movies. That is for obvious! But how do they effect ecosystems? They do that because when they are coming towards land, then they're carrying lots of ecosystems inside the waves, then, the animals in that go with the wave on the land, and then stay on the land while the water goes back to the ocean. So the thing is that the water needing animals will die in this situation. So they're damaging the ecosystems also.
Why is it difficult to avoid a tsunami?
The main thing is that natural disasters can't be avoided by humans in anyway. Humans don't have the capabilities to stop these things because these are the miseries of the world which we can't avoid. The reason why these happen is because of earthquakes underwater or also meteors falling on water. So that's why, these are unavoidable since we can't stop earthquakes and meteors. But we can put some effort into making the damage less by making giant walls and protection things. There are many technologies that can do this, but still, it will be hard since the water is liquid form, and it will take the form of it's container, meaning it will flow wherever it can. That's why it's HARD to avoid them.
