Human females produce egg cells through a process called oogenesis. This process involves stages of meiosis and maturation. Only a small number of egg cells will actually mature and be released during a woman's reproductive years.
Human females produce egg cells through a process called oogenesis. Oogenesis begins during fetal development, where billions of egg cells form in the ovaries. However, only a small number of these cells will actually mature and be released during a woman's reproductive years.
Oogenesis is a complex and regulated process that involves several stages. The primary stage is called meiosis, where the chromosomes in the developing egg cell undergo DNA replication and cell division to create haploid cells with half the number of chromosomes. These haploid cells are then referred to as secondary oocytes. The secondary oocytes undergo further maturation and, when fertilized by a sperm cell, can develop into a human embryo.

Answer: Cultural Evolutionism.
Cultural evolution is the theory that cultures change over time, similar to the evolution seen in biological organisms. It is based on the idea that cultures evolve and adapt to their environment and circumstances. An example is a transition from hunting-gathering society to an agricultural one based on the available land resources.
The view that cultures, like organisms, change over time is called cultural evolution. This theory posits that societal changes and developments happen gradually over time, analogously to the evolutionary changes seen in biological organisms. The concept of cultural evolution originates from 19th-century anthropology and was heavily influenced by Charles Darwin’s theory of natural selection. While there are debates and variations within this theory, at its base, it suggests that cultures evolve and adapt to their environment and circumstances, with these changes advantaging certain societies and helping them to succeed and prosper.
For instance, a culture that originally practiced hunting and gathering may evolve into an agricultural society when it encounters a fertile and productive land. This evolution of culture and society is not linear or inevitable, but dependent on a multitude of factors, including environmental, economic, and social conditions.

Explanation:
B
A Septum separates the heart's left and right sides to keep oxygenated and deoxygenated blood from mixing.
The septum of the heart is the wall that divides the left side of the heart to the right side.
The septum that divides the upper chambers of the heart is called the atrial septum.
The ventricular septum divides the lower chambers of the heart.
Thus., the correct option is b.) It separates the heart's left and right sides to keep oxygenated and deoxygenated blood from mixing.
