Answer:
Eukaryotes:
-Organisms with a well defined nucleus are known as eukaryotes. such cells are called as eukaryotic cells.
- Their nucleus is enclosed within the nuclear membrane.
- They do not posses a mitochondria.
- The cell wall is the outer most layer of a eukaryotic cell (only plant cells have a cell wall)
- The cells are divided by a process called mitosis.
Eg: Plants, Animals.
Prokaryotes:
- Organisms without a well defined nucleus are known as prokaryotes. Such cells are called as Prokaryotic cells.
- They lack nuclear membrane.
- Mitochondria, Golgi bodies, chloroplast and lysosomes are absent.
- The genetic material (DNA) is present on the chromosome.
Eg: Every organism coming under the kingdom monera.

The equator receives the most amount of solar radiation, therefore, they have warmer to hot climates.
Explanation:
Ribosomal RNA<span> (</span>rRNA<span>) associates with a set of </span>proteins<span> to form ribosomes. These complex structures, which physically move along an </span>mRNA<span> molecule, catalyze the assembly of amino acids into </span>protein<span> chains. They also bind </span>tRNAs<span> and various accessory molecules necessary for </span>protein<span> synthesis
