Answer:
Extinct Volcano
Explanation:
Extinct volcanoes are those that have not erupted in at least 10,000 years, and are also not expected to erupt again.
Dormant volcanoes are volcanoes that have not erupted, but are expected to erupt.

The answer is: phloem.
Answer:
B.
Explanation:
Proteins targeted to the mitochondrial matrix are unfolded during transport and refolded within the matrix, while proteins targeted to the nucleus are fully folded in the cytoplasm before nuclear transport. So, The correct statement is B.
Proteins targeted to the mitochondrial matrix are unfolded while being inserted into the mitochondria and are refolded within the matrix. Proteins targeted to the nucleus are completely folded into the cytoplasm before they are transported to the nucleus.
- Proteins targeted to the mitochondrial matrix are indeed unfolded while being inserted into the mitochondria. This unfolding allows them to pass through the mitochondrial membranes. Once inside the mitochondrial matrix, they can be refolded into their functional conformation.
- Proteins targeted to the nucleus are typically completely folded into their functional conformation in the cytoplasm before they are transported to the nucleus. The nuclear pore complex allows folded proteins to pass through while excluding unfolded ones.
So, The correct statement is B.

Answer:
Explanation:
Albinism, meaning "white,"
-Is a group of heritable conditions linked with low or absent melanin in ectoderm-derived tissues.
ectoderm-derived tissue -most notably the skin, hair, and eyes, yielding a characteristic pallor. The most commonly thought of presentation is that of oculocutaneous albinism (OCA).
Melanin is a pigment producing compound and it is responsible for determining the colour of skin and hair.
They have an increased susceptibility to Albinism and various genetic abnormalities and congenital defects.
People with albinism are unable to synthesize melanin, causing them to appear white. This lack of melanin also makes them more susceptible to sun damage and skin cancer.
People who have albinism appear white because they cannot synthesize the pigment melanin. Melanin is responsible for the colour in our skin, hair, and eyes, and those with albinism have either a reduced quantity or absence of this pigment. As a result, those affected with this condition have skin, hair, and eye color that is much lighter than the non-affected population. Due to the lack of melanin, they have an increased susceptibility to sun damage and skin cancer. Because melanin provides some protection against harmful UV radiation, people with albinism are more susceptible to sunburn and skin cancers.
