Laboratory rats and mice live up to 40% longer than usual when fed a diet of at least 30% fewer calories than that which they would normally eat, but that otherwise contains all necessary vitamins and nutrients.

(a) of at least 30% fewer calories than that which they would normally eat, but that otherwise
(b) with at least 30% fewer calories than what they would normally eat though otherwise it
(c) that has at least 30% fewer of the calories than they would normally eat, but otherwise it
(d) that has at least 30% fewer calories than they would normally eat but that otherwise
(e) that has at least 30% fewer calories than that which they normally eat, though that otherwise

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

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.
