Animal Tissues
Animal tissues are classified into four types: epithelial, connective, muscular, and nervous. Epithelial tissue covers body surfaces and lines organs, aiding in protection and absorption. Connective tissue supports and binds other tissues; it includes blood, bone, cartilage, and adipose. Muscular tissue enables movement and is divided into skeletal, smooth, and cardiac types. Nervous tissue, made of neurons and neuroglia, transmits signals and coordinates bodily functions. These
Types of I/O Devices: Block Data: Store data in fixed size blocks. Transfer happens in blocks (ex: SSD). Character Devices: Stream of characters, no block structure (eg: Keyboard,Mouse), also no seek operation. Difference between block vs. character devices: Block devices support random access and block lvl operations while character devices operate in a stream and cannot seek. I/O Communication Methods: Seperate I/O & Memory Space: Easier seperation, not flexible. Memory-mapped I/O: Part...

• Funciones:
• Exocrina: amilasa (carbos), lipasa (grasas), tripsina (proteínas).
• Endocrina: insulina ↓ glucosa, glucagón ↑ glucosa.
• Pruebas diagnósticas:
• TLI (Trypsin-Like Immunoreactivity): mide tripsina/tripsinógeno → útil en IPE (Insuficiencia Pancreática Exocrina).
• SNAP cPL/fPL (Canine/Feline Pancreatic Lipase): test rápido para pancreatitis.
• Elastasa fecal: se detecta en heces → también para IPE.

Science & the Universe
Astronomy = study of celestial objects and their interactions.
Scientific method: relies on observation, testing, and revision.
Distances measured in light-years; light travels at ~300,000 km/s

I/O Devices: Block Devices: Devices that store data in fixed-size blocks (512 byte or 4 kb) and allow random access. Used in hard drives, SSDs, DVDs.
Character Devices: Devices that send or receive a stream of characters. (Keyboard, mouse, serial ports.) (Why cant u seek with character devices?: Data comes in realtime stream) Memory-Mapped I/O vs Separate I/O Space: Separate I/O: CPU uses special instructions to communicate with I/O ports. Memory-Mapped I/O: I/O devices share the same address space...
Great question! Fourier Series and Fourier Transform are both mathematical tools used to analyze signals, but they serve different purposes.
Fourier Series: This is used to represent a periodic function as a sum of sines and cosines. It decomposes a repeating signal into its frequency components. Essentially, if you have a function that repeats over time, the Fourier Series breaks it down into simpler waves.
Fourier Transform:
