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.

Match each image of a mirror with the type of mirror that describes the shape.
Write the letter next to the term on the blank space in the provided image
A. flat mirror
B. convex mirror
C. concave mirror
Answer:
The top left mirror is C.) concave mirror. This is because the reflective surface is curved inward, creating a curve that is less than 180°. Remember, the reflective surface is the side the light strikes.
The top right mirror is B.) convex mirror. This is because the reflective surface bulges outward.
The bottom mirror is A.) flat mirror.

In a group of dogs, some individuals have short fur and others have long fur. In this gropp,
the gene for the fur length trait has two alleles. The allele F is for short fur, and the allele fis
for long fur.
Marley, a dog from this group, has long fur. Marley has two alleles for long fur.
Based on this information, what is Marley's phenotype for the fur length trait?
FF
FI
short fur
long fur
Answer:
long fur
Explanation:
Phenotype refers to an individual's observable traits, such as height, eye color, and blood type ( the outside apperance ) so what is the dog's fur can be discribed as ? the answer is long fur

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

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.
Thanks!
