14 mag 2024 · Microinjection is a sophisticated technique employed in the realm of molecular biology and genetics. It involves the direct introduction of DNA or other genetic materials into a cell. This is achieved using a micropipeta or a fine glass needle, specifically designed for this purpose. La principal ventaja de la microinyección es su capacidad ...
26 apr 2024 · – Definition In biology, an analogy refers to a comparison between two different biological structures or processes that perform similar functions despite having evolved independently. This concept is pivotal for explaining evolutionary phenomena, illustrating how distinct species can develop comparable traits as a result of facing similar environmental challenges.
10 mag 2024 · RESPIRATION: The anatomy of the avian respiratory system is quite complex compared to that of mammals. The avian and mammalian respiratory systems consist of the lungs which expand, gas exchange occurs and the air is exhaled. In birds the respiratory system also serves for the exchange of gases but is also important in eliminating heat from the body and has several non-respiratory functions ...

12 mag 2024 · A Golgi apparatus is composed of flat sac-like structures known as cisternae. The sacs are stacked in a bent, semicircular shape. Each stacked grouping has a membrane that separates its insides from the cell’s cytoplasm. The Golgi bodies are very polar. Stacks may change in number in each cell i.e. 16, 18, and 20.

12 mag 2024 · The cell membrane, or the plasma membrane, exists in all cells and is a boundary between the cell’s interior and the external environment. It is composed of a lipid bilayer that is selectively permeable. The cell membrane plays a vital role in controlling the movement of substances into and out of the cell.
