Sperm competition is the competition between sperm from different males to fertilize the same female's eggs. In many species, females may mate with multiple males. This has led to the evolution of various adaptations in males. For example, some male animals produce large quantities of sperm to increase the chances of their sperm reaching and fertilizing the egg. Also, the shape and motility of sperm can be specialized for better competition. In some insects, male genitalia have evolved in complex ways that may help them remove or displace the sperm of rival males already present in the female reproductive tract.
Physics Wallah's real story is quite inspiring. Alakh Pandey was just an ordinary teacher with an extraordinary idea. He noticed that many students were struggling with physics, especially those from middle - class and lower - middle - class families who couldn't afford expensive coaching classes. So, he started creating content on YouTube. His videos were not only informative but also engaging. He would break down difficult topics into smaller, digestible parts. As his popularity grew, he used the revenue from ads and sponsorships to improve the quality of his content and eventually launched his own educational platform, which has now become a major player in the online education space in India, providing quality education at a reasonable cost.
One key aspect is its origin from a need for affordable education. Alakh Pandey identified the gap in the market for quality yet inexpensive physics teaching. Another aspect is the power of online platforms. By using YouTube, he was able to reach a large number of students without the need for a big infrastructure. Also, his teaching methodology, which was student - friendly and focused on concept clarity, played a huge role in the success of Physics Wallah.

Biology was not literature.
Biology was a science that studied life phenomena and organisms. It mainly focused on the nature, composition, evolution, growth, development, disease, health, and other aspects of life. Literature is an art subject that focuses on language, imagination, emotions, and expression. It aims to convey the author's thoughts, emotions, and values through words.
Although biology and literature intersected, they were fundamentally different. Biology was a natural science that required experiments, observations, and theoretical models to explain biological phenomena, while literature was an art form that required words, poems, plays, novels, and other means to express the author's thoughts, emotions, and values.
Therefore, biology was not a part of literature, but there was a certain connection and intersection between the two.
