Explaining Biology on Instagram: "An egg is made inside a hen through a step-by-step biological process that takes about 24-26 hours from start to finish. It begins in the ovary, where the hen releases a yolk. The yolk already contains all the nutrients needed to feed a developing chick if the egg is fertilized. The yolk then moves into the oviduct, a long tube where the rest of the egg forms. In the first section, the egg white (albumen) is added. This thick, clear liquid surrounds the yolk and

Explaining Biology on Instagram: "This mesmerizing microscopic view reveals a rotifer, a tiny aquatic organism known for its remarkable feeding structure called the corona. The corona appears to rotate, but in reality, it is made of rapidly beating cilia that create powerful water currents. These currents pull in food particles such as algae and bacteria, guiding them toward the rotifer’s mouth with incredible precision. Beyond feeding, the corona also helps the rotifer move through its watery e
