After an organism dies, its C-14 to C-12 ratio "remains constant".
<u>Answer:</u> Option C
<u>Explanation:</u>
Carbon dating is the evaluation of organic matter's age from the C-12 & C-14 relative proportions contained by matter. Soon after the death of organism new carbon inhalation stops. While the ratio of these carbon isotopes at the moment of death remain same as rest of the living things.
But C-14 decays by having half life of 5700 years and C-12 amount remain same in the organic matter. The ratio of C-12 to C-14 in any dead organic matter is compared to ratio in a living matter with the intention of determining the age of a formerly living thing in most precise manner.
The fatty acids in the tail of a phospholipid molecule are non-polar and hydrophobic.
Fats that you take in from your food is used to build membranes. Membranes can be represented by models such as The Fluid Mosaic Model, which displays the phospholipid bilayr, and other tissues on the membrane.
