fermentation tube and the PRESENCE of gram-negative, non-spore-forming, rod-shaped bacteria in the agar culture may be CONSIDERED a satisfactorily completed test, demonstrating the positive presence of COLIFORM bacteria in the analyzed sample.

ong>Answer:

1)Least count of any DEVICE.

The SMALLEST length which can be be measured by metre scale is CALLED least count.

Least count of the instrument (L.C)

= Value of one main scale division / TOTAL number of vernier calipher division.

2)What do you know about pitch of screw gauge?

The pitch of screw is the distance moved by the tip of the screw for one complete ROTATION of the head.

3)Can you find the diameter of a thin wire of length 2m?

No ,we can use vernier calipher to measure the diameter of a thin wire of length 2m.

The SI unit of acceleration is metres/second2 (m/s2). FORCE (F), MASS (m) and acceleration (g) are LINKED by Newton's Second LAW, which states that 'The acceleration of an object is directly proportional to the net force ACTING on it and inversely proportional to its mass'.

Converting ENERGY from one form to another is the key to understanding the DIFFERENCES between electric motors and generators. An electric motor converts ELECTRICITY into mechanical energy, providing a power source for machinery. A generator does the OPPOSITE of this, converting mechanical energy into electricity.

How To Genetically Modify a Seed, Step By Step

USING nature as a guide, geneticists build plants with qualities evolution could never produce

By Rebecca Boyle

January 24, 2011

ST. LOUIS — In a nondescript basement lab, jeans-clad engineers clutch blueprints, scrape stepladders across the unfinished floor and chat about the Cardinals as they tighten bolts on a new prototype device. At first glance, it could be any machine shop in the country.

But then you notice the wispy strands of soybean seedlings curling to life, their ROOT tendrils bunched into test tubes lightly PACKED with soil, and you remember — this place is all about seeds.

Monsanto Co. produces 90 percent of the world's transgenic crops, using a complex marriage between ancient techniques — cross-breeding different plants to produce a desired trait — and the most modern technologies available, from genomic research to NASA-caliber mechanical engineering.

Originally a chemical company, Monsanto produced some of the world's most controversial substances — saccharine, DDT, PCBs, Agent Orange — before evolving into the biotech giant it is today. That evolution has been marked by controversy, including lawsuits against farmers, allegations of unfair trade practices, and more. The company produces the herbicide Roundup, and also seeds whose genes have been engineered to survive Roundup's active plant-killing ingredient. Now the vast majority of this country's soybeans, corn, sugar beets and canola possess those engineered genes.

Behind EVERY single seed is at least a decade of research involving geneticists, engineers and farmers, working to produce a seed that will grow exactly as expected, and in a way nature may not have intended. Here's how it's done.

Step one: Finding a new trait

Ginny Ursin, head of technology prospecting at Monsanto, has been studying plants most of her life; at age 10, she cobbled together a makeshift greenhouse in the front yard. It was well-built enough that a city building inspector dropped by to inquire about a permit, she recalled. After obtaining her Ph.D in genetics from the University of California-Davis, she studied the biochemical pathways that allow plants to accumulate oil. She has spent more than a decade developing a new omega-3 soybean, which actually produces a precursor fatty acid that our bodies convert into a heart-healthy type of omega-3 — fish oil without the fish. Its history includes Alaskan wildflowers, a type of mold used in Indonesian cooking and years of patient cultivation.

ong>Answer:

Rotating magnetic FIELDS are ALSO used in induction MOTORS. Because magnets degrade with TIME, induction motors use short-circuited rotors (instead of a magnet) which follow the rotating magnetic field of a multicoiled stator.

When it rains, where does it go? Once on the land, rainfall EITHER seeps into the ground or BECOMES runoff, which flows into RIVERS and lakes. ... The rate of rainfall: A lot of rain in a short period tends to run off the land into STREAMS rather than soak into the ground.
