Cell Models

Cell Models
For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy. Reproduction / cell division Energy trapping, storage and consumption Form / shape / structure Cell specialization Compartmentalization of cell functions Communication within and beyond the cell Cell / organism survival

PocketQube Kit v1.0 EM — PocketQube Shop Structure Skeletonized Structure, designed for the PocketQube Standard (Pico-satellite class). Aerospace grade aluminium structure with plated finish (flight model only) with two micro-switches for double redundancy (kill switches). Can accommodate PCB board stack such as PQ60 v1.0. Brochure/Dataheet: 1p, 2p, 3p, On Board Computer (OBC) Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification.

Interactive Ear tool showing how the ear works by Amplifon The ear is the organ which controls hearing and balance, allowing us to understand our surroundings and position ourselves correctly. It is split into three parts: outer, middle and inner. This guide will take you through each part of the ear in turn, answering those essential questions – what are the parts, what do they do, and how? Pinna Helix How Cells Divide share By Rick Groleau Posted 10.09.01 NOVA Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes.

Lantern: One Device, Free Data From Space Forever Global access to the web’s best content on your mobile device. Anonymous. Uncensored. The Cytoskeleton Cells contain elaborate arrays of protein fibers that serve such functions as: establishing cell shape providing mechanical strength locomotion chromosome separation in mitosis and meiosisintracellular transport of organelles The cytoskeleton is made up of three kinds of protein filaments: Actin filaments (also called microfilaments) Intermediate filaments and Microtubules Actin Filaments Monomers of the protein actin polymerize to form long, thin fibers. These are about 8 nm in diameter and, being the thinnest of the cytoskeletal filaments, are also called microfilaments. (In skeletal muscle fibers they are called "thin" filaments.) Intermediate Filaments

50 Really Cool Online Tools for Science Teachers A 21st-century education revolves around the Internet for everything from collaboration, tools, lessons, and even earning degrees online. If you are looking for ways to integrate online learning into your science class or science degree programs, then take a look at these cool online tools that are just perfect for both teachers and students. Science Tools to Use with Students These tools offer opportunities for learning about climate, cells, the human body, nature, and more. Small Movies of Cell Bio Topics Interactive tutoring on the toughest topics in biology Have you ever wished for an effective tool to help your students visualize tough topics like a tour of the plant and animal cell, cellular respiration, photosynthesis, mitosis, meiosis, protein synthesis, or how neurons work? Our new 3-minute animations allow instructors to show 3D, fluid movement and dramatic "zoom" sequences that bring difficult-to-teach biological concepts to life during lectures.

Prizm - Turn your speakers into a learning music player by Prizm Whether you are alone at home, with family, or partying with friends, Prizm adapts and predicts the music you’ll love. Prizm streams music directly from the Cloud so you don’t even need to use a phone or a computer. You can now discover and enjoy more music with a single hit of a button. Press play and the music starts. Music streams directly from the cloud to your speakers. Membranes Organize Cellular Complexity Membranes organize proteins and other molecules enabling the cell to run much more efficiently than if everything were floating freely. Mitochondrial membranes, for example, keep protein assembly lines together for efficient energy production. And the lysosome safely holds enzymes that would destroy essential proteins if released into the cytoplasm. Membrane-enclosed vesicles form packages for cargo so that they may quickly and efficiently reach their destinations. In this way, membranes divide the cell into specialized compartments, each carrying out a specific function inside the cell.

The Integrated Circuit Lists of Nobel Prizes and Laureates The Integrated Circuit Play the Techville Game About the game Integrated circuits, also called "chips", are electronic circuits where all the components (transistors, diodes, resistors and capacitors) has been manufactured in the surface of a thin substrate of semiconductor material. Read More » DNA-RNA-Protein DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell. The DNA is situated in the nucleus, organized into chromosomes. Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication).

danielrapp.github Recently I stumbled upon an interesting paper for implementing motion sensing requiring no special hardware, only a speaker and mic! Unfortunately the paper didn't include code to test it, so I decided to reproduce it here on the web! What is the doppler effect?
