The domestication of plants and animals resulted in the development of villages and cities. The growth of early settled communities contributed to the development of political and religious institutions.

The term "domestication" refers to taming an animal, growing plants for sustenance, making someone lovable and devoted at home, as well as undertaking chores related to that profession or vocation. The domestication of plants and animals in areas near the Indus, Huang he, nile, and tigris-euphrates rivers resulted in the development of villages and cities which in turn contributed to the development of political and religious institutions.

The domestication of animals refers to the mutual relationship between animals and humans who influence their care and reproduction. It means to adapt (an animal or plant) over time from a wild or natural state, particularly through selective breeding to live in close association with and to the benefit of humans.

Organelles. Name them and tell what they are composed of?

VikaD [51]

Nucleus, vacuole, Golgi apparatus, ribosomes, rough endoplasmic reticulum, vacuole, Mitochondria, Smooth Endoplasmic Reticulum, Lysosomes, centriole are the organelles.

Explanation:

Organelles are the membranous cellular structure inside the cell performing specialised functions.

Nucleus: It consists of DNA, the genetic material, chromosome, histone proteins, nuclear envelope.

Vacuole: These are membranous organelles having water, inorganic and organic molecules, waste material and nutrients.

Mitochondria: They have two phospholipid bilayers and proteins, cristae and matrix.

Smooth Endoplasmic Reticulum: It is made up of tubules and vesicles that eventually forms a branch.

Rough Endoplasmic Reticulum: It is composed of tubules, vesicles and cisternae and held by cytoskeleton.

Golgi Apparatus: It has cisternae placed in stacks and lumens, stores the protein to be modified.

Lysosomes: It is composed of lipids and proteins. It has a single layer membrane, lysosome enzyme.

Ribosome: It is made up of rRNA and rProtein.

Centrioles: These are made up of proteins named microtubules.
