Santy (2004) is widely considered the first webworm - it spread by exploiting a vulnerability in phpBB web forum software and used Google to identify new targets. Sasser spread via Windows SMB vulnerabilities. Witty worm targeted ISS security products via network. Bandook is a trojan, not a worm. Santy was unique because it used search engines to find and propagate through web applications.

OSX/Leap-A (also called Oompa-Loompa) in 2006 is recognized as the first malware specifically targeting Mac OS X. Mocmex targeted Windows. Torpig is a Windows trojan. Rustock.C is a Windows botnet. Leap-A was a significant milestone as it demonstrated that Mac OS X was not immune to malware, though it required user interaction to spread via iChat.

Koobface (2008) specifically targeted social networking platforms, primarily Facebook and MySpace. It spread by sending fake links from infected accounts, tricking users into downloading malware. Conficker exploited Windows vulnerabilities. Daprosy worm targeted Yahoo Messenger. Stuxnet was a sophisticated cyberweapon targeting industrial control systems. Koobface's social engineering approach was unique to social networks.

CNN's tagline has been 'Go Beyond' or 'Go Beyond Boundaries' as part of their branding campaigns. This represents their commitment to comprehensive news coverage that goes deeper than surface-level reporting. CNBC is business-focused, Time and Times Now are not primarily news channels with this identity.

Golden Rice is a genetically modified (transgenic) rice variety engineered to produce beta-carotene, a precursor of vitamin A. It was created by inserting genes from daffodil and bacteria into the rice genome to address vitamin A deficiency in developing countries. Normal tomato, white brinjal, and brown rice are not examples of transgenic plants.

Gene therapy is a medical technique that involves inserting, altering, or replacing genes within an individual's cells and tissues to treat or cure disease. It's not about genome identification (option A) or traditional breeding (option B). Option C accurately describes the therapeutic application of genetic material to treat diseases at their genetic root.

The cheetah (Acinonyx jubatus) is the only living species among the options. The dodo became extinct in the 17th century, Brontosaurus is an extinct dinosaur genus, and mammoths went extinct around 4,000 years ago. Cheetahs still survive in the wild, primarily in Africa and a small population in Iran.

Perspiration (sweating) is the body's primary cooling mechanism. When sweat evaporates from the skin surface, it removes heat energy, helping to regulate body temperature. Respiration is for gas exchange, mastication is chewing, and urination is for waste elimination.

The name Cobalt originates from the German word 'Kobold', meaning goblin or demon. German miners gave cobalt ore this name because they considered it a troublesome ore that produced toxic arsenic fumes when smelted and seemed to be 'haunted' by demons.

Nerve impulses use the sodium-potassium pump, where Na+ ions are pumped out and K+ ions are pumped in (and vice versa during action potential). This creates the electrical gradient. These elements are ideal because they're lightweight, readily available in diet, and have maximum electrochemical polarity.
