Final review 2

Ribosomes are organelles that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Humans typically have 23 pairs of chromosomes, which contain the genetic information necessary for development and functioning.

A sequence of 12 nucleotides codes for 4 amino acids, as each amino acid is coded by a triplet of nucleotides.

The reduction in air pollution allowed the pale Peppered Moths to become more common again, as their coloration provided better camouflage against lighter surfaces.

Overproduction refers to the phenomenon where organisms produce more offspring than can survive, leading to competition for resources.

A mutation is a change in the DNA sequence that can lead to variations in traits among individuals.

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

The nucleus is the organelle that houses the cell's genetic material (DNA) and controls cellular activities.

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
