Scientific consensus supports the idea that living organisms require oxygen. Then, a scientist discovers a type of bacteria that metabolizes sulfur instead of oxygen, and thus survives in environments without oxygen. The scientist concludes that a diverse group of many different organisms could live in an oxygen-free environment.
The reason why some scientist should be skeptical of the scientist’s results and conclusion is to evaluate experimental procedures and it also helps scientists recognize when ideas are not supported by evidence. This is the way that this theory can become a scientific consensus.

As we know our blood has four main components which are plasma, red blood cells, white blood cells and platelets. That is why a hemophiliac must receive regular injections of platelets to stay alive. This is done by injecting into their bloodstream human plasma which contains many proteins, glucose, clotting factors, electrolytes, hormones, and carbon dioxide.

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.

A) ribosomes
B) Golgi bodies
C) mitochondria
D) endoplasmic reticulum
Answer:
The correct answer would be B) Golgi bodies
Golgi body is a cell organelle made up of vesicles and folded membranes.
It is mainly associated with the storage, modification, and packaging of macromolecules such as proteins and fats.
Macromolecules with the help of vesicles are transported from the endoplasmic reticulum to cis-Golgi bodies.
They are then modified in the folded membranes of the Golgi.
Post-modification they are transported to the different parts of the cell with the help of vesicles.
