Answer -
RNA - Stands for (ribonucleic acid)
The difference between RNA and DNA is difference in sugar and the make up of the back bone. For example in DNA it has deoxyribose (hint) why its called deoxyribonucleic which is one less O2 then ribose.
In addition they have different back bones in which are in
DNA its adenine, guanine, cytosine, thymine.
RNA its adenine, guanine, cytosine, uracil.
Can make a big difference trust me with those compounds.
Cell wall- around the cell
Cell membrane- in the cell wall
Vacuole- large storage area
Nucleus- protects nucleolus
Nucleolus- inside of nucleus
Cell membrane- surrounds nucleus as protection
Chloroplast-makes plant green
Mitochondrion-produces energy
Ribosomes-converts amino acid
The most likely reason is because of the decrease of population of prey in the south
