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.

Answer:
Half of the males are colorblind, dwarf and the other half colorblind, normal height.
Explanation:
The achondroplastic dwarf man with normal vision has a DdXY genotype. He marries a color-blind woman of normal height, so the hergenotype is ddX (c) X (c). All males will be colorblind as they inherit the X (c) chromosome from their mother. Half of them will be of normal height. So half of her boys will be colorblind and of normal height. To see how it works genetically, the cross is:
DdXY x ddX (c) X (c)
Your children have one of the four possible genotypes:
DdXX (c) (female, normal vision, colorblind carrier, dwarf)
DdX (c) Y (male, colorblind, dwarf)
ddXX (c) (woman, normal vision, color blindness carrier, normal height)
ddX (c) Y (male, colorblind, normal height)

When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time. Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.
Answer:

Its D, species began having more beneficial adaptions to their environment causing them to live longer.
Answer:
It's D. Species can better survive environmental changes.
The accessory organ that has secretions that can neutralizestomach acid before it reaches the intestines is the pancreas. The pancreasproduces and secretes sodium bicarbonate, which can protect intestines byneutralizing stomach acid. This may also relieve symptoms of acid refluxtemporarily.
