Like bacteria(prokaryotes), eukaryotic organisms can develop mutations in DNA that can affect traits, but these mutations are rare. Unlike bacteria, most multicellular organisms reproduce sexually- that is, two parents each produce cells called gametes that contain 1/2 the DNA needed for an organism. When gametes from two separate parent organisms fuse to form a single cell (zygote), that will develop into a juvenile, that is not identical to its parents. Identify THREE events in the process of creating gametes and forming a zygote that result in this natural variation.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
