A tRNA isoacceptor is a member of a group of tRNAs with different anticodons but which accept the same amino acid.
An anticodon is a small region on transfer RNA (tRNA) that comprises of three bases which are complementary to a codon in messenger RNA (mRNA). A codon is simply a set of three nucleotide bases.
If a codon in mRNA is GGG, the anticodon on tRNA for this will be CCC. The codon GGG is the code that calls for the amino acid called glycine.
It stands for Ribonucleic Acid
Genetic information from DNA

Derived characteristics refers to those traits that have changed from ancestral form or function. The derived character, which cause K. monera to be divided into K. archeabacteria and K. eubacteria is that genetically and biochemically the two are different. The archeabacterial possess unusual lipid, which is not find in eubacteria or any other organism. And this give it the capacity to live in extreme environments.
With sleep deprivation, the levels of leptin fall and the levels of ghrelin rise.
What is leptin ?
Your body secretes a hormone called leptin that aids in long-term maintenance of your normal weight. Your blood's concentration of leptin and how much body fat you have are intimately correlated. Despite the fact that your body has enough fat reserves, leptin resistance makes you feel hungry and make you eat more.
What is ghrelin ?
Small amounts of ghrelin are also released by the small intestine, pancreas, and brain. Ghrelin is primarily synthesized and released by the stomach.

C is correct. the rest is either about food webs or about both food webs and food chains.
