Answer from: abbyxtv

D) rickets

Explanation:

Rickets is a type of skeletal disorder that is characterized by softening and weakening of bones which often result to bowed legs or knock knees in children.

Rickets is said to be caused by lack of vitamin D, calcium or phosphate. Vitamin D is said to aid the absorption of calcium and phosphorus, which are important elements in the building of strong and healthy bones.

Vitamin D can naturally be produced in the body when the skin is exposed to adequate radiation of the sun. Vitamin D along with calcium can be gotten from diets rich in diary products also.

Considering the information given about Isaac in the question, we can infer that Isaac has a high risk of rickets, since Isaac gets little exposure to sunlight, and he doesn't consume diary foods because he is lactose intolerant, deficiency of vitamin D would set in. As a result of the lack of vitamin D, calcium and phosphorus, the probability of Isaac developing rickets is high.

Answer from: sgslayerkingminecraf

D) rickets

Explanation:

Ricket is a disease occurs due to the deficiency of vitamin D. This disease occurs in those children who cannot consume foods which contains vitamin D. Deficiency of Vitamin D, bones becomes very soft and easily be broken and fractured. Our bones are madeup of calcium which can be absorbed from the calcium containing food with the help of vitamin D. Isaac has lactose intolerance so thats why he cannot eat calcium containing foods such as dietary products and has a high risk of ricket disease.

Answer from: Quest

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
