Chromatin- a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells
Anti-codon- a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule
Ribosome- a complex molecular machine that produces proteins from amino acids. They are found in both prokaryotic and eukaryotic cells
Double-helix- the structure formed by double-stranded molecules of nucleic acids
Lysine- a building block for protein and an essential amino acid
False, there are lots of biomes on earth.
Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts.

The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
