2. Biological life cycle - Wikipedia

   en.wikipedia.org/wiki/Biological_life_cycle

   In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...

5. Development of the human body - Wikipedia

   en.wikipedia.org/wiki/Development_of_the_human_body

   Human embryonic development refers to the development and formation of the human embryo. It is characterised by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, human development entails growth from a one-celled zygote to an adult human being.

   The initial stages of human embryogenesis Parts of a human embryo. Ontogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development [1]), usually from the time of fertilization of the egg to adult.

7. Sexual reproduction - Wikipedia

   en.wikipedia.org/wiki/Sexual_reproduction

   Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes .

   Life cycle of the eucestode Taenia: Inset 5 shows the scolex, a disk with hooks on the end. Inset 6 shows the tapeworm's whole body, in which the scolex is the tiny, round tip in the top left corner, and a mature proglottid has just detached.

9. Circannual cycle - Wikipedia

   en.wikipedia.org/wiki/Circannual_Cycle

   In chronobiology, the circannual cycle is characterized by biological processes and behaviors recurring on an approximate annual basis, spanning a period of about one year. This term is particularly relevant in the analysis of seasonal environmental changes and their influence on the physiology, behavior, and life cycles of organisms.
