1) Lipids are the waxy, greasy, oily molecules found in the body.
2)They are water-insoluble (hydrophobic), and this property is useful in the organisation of cells and tissues.
3)Lipids can be extracted from cells using non-polar solvents . Example chloroform or benzene.
Together, the spindle fibers from either centriole guide the chromosome to the center of the mitotic spindle. This stage of mitosis is called metaphase and the arrangement of chromosomes lined up in the center of the mitotic spindle is referred to as the metaphase plate.
Answer: 4282.928 = 4283 years
Explanation:
Data given;
Carbon 14 half life = 5740
No (initial radiation) = 0.230 Bq/g
Nf (final radiation) = 0.137 Bq/g
First we find the decimal fraction of the remaining half life of the carbon 14
k = No / Nf
k = (0.137 / 0.230) = 0.595652
So to find how many half-life has elapsed, we say
(1/2)^n = k
(1/2) ^n = 0.595652
Therefore
n log 0.5 = log 0.595652
n = ( log 0.595652) / ( log 0.5)
n = 0.747457
To get the elapsed time or how old the sample is;
We say
Carbon 14 half-life × n
5730 yrs × 0.747457
= 4282.928
= 4283 years.
So the sample of the wood is 4283 years old.
