Huntington’s disease is a genetic disorder that is caused by a dominant allele. which of the following is true?
a. a person with huntington’s disease will pass the disease onto 100% of their children.
b. a child who inherits one copy of the gene that causes huntington’s disease will have the disease.
c. a child who inherits one copy of the gene that causes huntington’s is a carrier for the disease.
d. huntington’s disease tends to skip generations.

The correct answer will be option B.

Explanation:

Huntington's disease is an autosomal dominant disorder that means even if there is only one copy of the gene is present, the person will be affected by this disorder. A person with Huntington's disease will pass the disease onto 50% on his children if another parent is with the normal gene. A person cannot be a carrier as only one copy of the gene is enough to affect the individual for the disorder.

Thus, the correct answer would be option B.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
