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.

Answer:

Extinction is often caused by a change in environmental conditions. When conditions change, some species possess adaptations that allow them to survive and reproduce, while others do not. If the environment changes slowly enough, species will sometimes evolve the necessary adaptations, over many generations.

Answer:

Explanation:

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Asexual reproduction is observed in both multicellular and unicellular organisms. This process does not involve any kind of gamete fusion and there won’t be any change in the number of chromosomes either. It will inherit the same genes as the parent, except for some cases where there is a chance of a rare mutation occurring.

The term “fission” means “to divide”. During binary fission, the parent cell divides into two cells. The cell division patterns vary in different organisms, i.e., some are directional while others are non-directional. Amoeba and euglena exhibit binary fission.

It is one of the simplest and uncomplicated methods of asexual reproduction. The parent cell divides into two, each daughter cell carrying a nucleus of its own that is genetically identical to the parent. The cytoplasm also divides leading to two equal-sized daughter cells. The process repeats itself and the daughter cells grow and further divide.

Fragmentation is another mode of asexual reproduction exhibited by organisms such as spirogyra, planaria etc. The parent body divides into several fragments and each fragment develops into a new organism.

Regeneration is the power of growing a new organism from the lost body part. For eg., when a lizard loses its tail, a new tail grows. This is because the specialized cells present in the organism can differentiate and grow into a new individual. Organisms like hydra and planaria exhibit regeneration.

Budding is the process of producing an individual through the buds that develop on the parent body. Hydra is an organism that reproduces by budding. The bud derives nutrition and shelter from the parent organism and detaches once it is fully grown.

Asexual reproduction in plants occurs through their vegetative parts such as leaves, roots, stems, and buds. This is called vegetative propagation. For example, potato tubers, runners/stolon, onion bulbs, etc., all reproduce through vegetative propagation.

Spore formation is another means of asexual reproduction. During unfavourable conditions, the organism develops sac-like structures called sporangium that contain spores. When the conditions are favourable, the sporangium burst opens and spores are released that germinate to give rise to new organisms. In asexual reproduction, a single cell is divided to produce offspring. Simple cell-by-cell division is not possible in multicellular organisms. Most of the multicellular organisms have a complex body design. They have a higher level of organization like tissues, organs and organ systems. Thus, they need a special mode for reproduction.

Answer:

1. Osteology

Clavicle can be use to determine the age of a person by measuring it's length when it stop growing. It is the last bone that grow at age 25.

3. Pelvis can be use to determine sex of an individual.

The female pelvis has space for birth canal while the male pelvis does not have.

4. Isotopes in human tooth enamel or bones can tell us about changes in dietary shift or dietary life history of an individual.

Explanation:

Osteology is the scientific study of bones, skeletal elements,teeth's, morphology, function, diseases and bones resistance.

Clavicle or collar bone is the long bone between the shoulder blade and sternum. This comprises of the shoulder girdle.

It is the first bone to begin ossification during embryonic development and it developed in humans between 21 to 25 years of age.

Answer:

Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.

(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.

(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.

(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.

(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Answer:spectrum

Explanation:

Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.

So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.

But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.

So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?

Well, if you analyze the text you have transcribed, there appear to be the letters "d", "e", "e", "z", plus, "n", "u", "t", "s."

Assuming you were to combine all of these letters together, the revised text would look as follows:

"Deez nuzts."

However, things are not that simple. Why, you may ask?

Because there is something missing in this transcript.

I believe an additional "your mom" would need to be added.

This results in the final transcript,

"Your mom loves deez nuzts."

But wait! We're not done yet.

This is because this sentence is wordy, and hard to read. It undermines the writer's message and the word choice is bland. Grammarly's cutting edge technology helps you craft compelling, understandable writing that makes an impact on your reader. Much better.
