Wildflower seed. Coloured scanning electron micrograph (SEM) of a seed from awildflower. Wildflower is a general term for flowers growing wild in nature. A seed contains an embryo (a fertilised ovule from which a new plant can grow), and a supply of food. The food is used either while the embryo grows within the developing seed, or during germination. Seed shapes and surface textures vary widely, affecting how they are dispersed from their

Description

This excellent introduction to the study of all living things is a visually stimulating journey through the saga of the cell; its history, components, and function.

Part 1 - traces cell discovery back to early scientists such as van Leeuwenhoek and Hooke. The CELL THEORY is introduced along with the technological advances of the microscope.

Part 2 - takes the students inside a cell, starting with one celled organisms and moving on to plant and animal cells. Cell parts are examined and compared.

Part 3 - demonstrates the starting process of cell reproduction, MITOSIS, and MEIOSIS.

Part 4 - explores GENETICS, as students follow the function of the two master molecules, DNA and RNA.

Suggested questions, disucssion topics, and reproducible activities reinforce the video. For High School to Adult Education. Running time is 26 minutes.

Description

Activeion strives to protect the health and safety of all people, and foster a more sustainable world, by creating revolutionary, chemical-free cleaning and anti-microbial technologies for everyday use. The ionator HOM from Activeion is an easy-to-use, versatile appliance that removes dirt and kills 99.9% of harmful germs without the use of chemicals when used as directed. It's designed for quick and portable cleaning around your home, in your car, or at your office. You can use it to easily clean glass, stainless steel, marble, granite, tile, carpet, fabrics and more. From kitchens and bathrooms, to bedrooms and playrooms--you can clean without leaving behind any chemical residue. With the ionator HOM, you will significantly reduce the repeated high expense, potentially toxic harm, and enormous packaging waste that come from using general-purpose cleaning chemicals. The science inside the ionator HOM. Using the ionator HOM After charging the battery, just fill the removable reservoir with plain tap water, squeeze the trigger to spray the surface to be cleaned and wipe the surface dry with a clean cloth. Plain tap water is all you need as the ionator HOM technology requires some mineral content in the water to function properly. The relative hardness or softness of the water does not matter. The technology has the engineering "smarts" to sense the mineral content and will adjust appropriately to give you consistent cleaning and sanitizing performance. How does it clean? When the trigger is pressed, a slight electrical charge is applied to the tap water and the charged water passes through an ion exchange membrane to create an oxygen-rich mix of positively and negatively charged nanobubbles. These nanobubbles are electrically charged and attach themselves to dirt particles (think magnets). As the charges from the nanobubbles build up on the dirt particles, they separate from one another and break apart due to repulsion of like electrical charges. The dirt particles become suspended in the charged water—allowing the dirt to be easily wiped away. The nanobubbles stay active for approximately 30-45 seconds before returning to their natural state. How does it sanitize? When used as directed, the ionator HOM kills the 2009 Pandemic H1N1 Influenza A virus and more than 99.9% of most harmful bacteria like E. coli, VRE, Salmonella, MRSA, Pseudomonas, Staph, Listeria and E. coli O157:H7 on nonporous hard surfaces. The core science used in the ionator HOM to sanitize is known as electroporation. An important tool in molecular and cellular biology for medical research, electroporation uses a low-level electrical field to disrupt cell membranes. The ionator HOM applies a low-level electrical field to the water. The water then carries this electrical field to the surface where germs reside, disrupting the germ’s membranes and killing them. These images were taken with a scanning electron microscope and show E. coli and Staph bacteria before and after applying the technology used in the ionator HOM to kill them within 6 seconds. No chemical-related health warning labels Despite its harm to germs, independent laboratories have conducted extensive testing on this technology to international and U.S. standards to confirm that it has zero measurable detriment on skin, eyes, when ingested or inhaled. The data from these tests have been reviewed by the EPA for compliance and, as a result, absolutely no chemical-related health warning label is required for the ionator HOM. Think physics, not chemistry The science of electrolysis is over 100 years old, and the science of electroporation has been around for decades. Before Activeion, products incorporating these technologies cost thousands of dollars or were only available in specialized laboratory equipment. Activeion is the first to combine the science of electrolysis and electroporation into a small, handheld appliance available to everyone. Activeion’s technology does not rely upon any slight changes in the water’s pH levels and oxidation reduction potential (ORP) to clean or sanitize, nor does it add salt to create hypochlorous (a form of bleach water). It relies upon physics and electrical engineering rather than traditional chemical-based cleaning processes. Simple. Smart. Sustainable. The ionator HOM is designed to replace many of the general-purpose cleaners and some of the specialty chemicals people use every day, but it is not a miracle cleaner. As with other products, there may be big cleaning jobs such as heavy build up or entrenched stains that may require alternative methods. However, the ionator HOM is proven to be an effective general-purpose cleaner and sanitizer that empowers you to reduce the exposure you and your loved ones face on a daily basis to many potentially harmful cleaning chemicals.

Features

• On-demand, hand-held appliance for daily-use cleaning and sanitizing without chemicals
• Kills 99.9% of harmful germs on nonporous hard surfaces when used as directed
• Advanced technology converts tap water into ionized water--a versatile and effective dirt-lifting agent
• Cleans a variety of surfaces including glass, stainless steel, marble, granite, tile, carpet, fabrics, and much more
• Built-in 12-volt nickel-metal hydride (NiMH) rechargeable battery provides one to two weeks of portable cleaning power on a single charge
