    The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. Although glucose is the preferred carbon source for most bacteria, the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta-galactosidase.[1] Gene regulation of the lac operon was the first genetic regulatory mechanism to be understood clearly, so it has become a foremost example of prokaryotic gene regulation.

    The examples of bacteria that release gases during metabolism are:

    (a) Bacteria and fungi carry out the process of fermentation and during this process, they release carbon dioxide. Fermentation is the process of converting a complex organic substance into a simpler substance with the action of bacteria or yeast. Fermentation of sugar produces alcohol with the release of carbon dioxide and very little energy.

    (b) The dough used for making idli and dosa gives a puffed appearance. This is because of the action of bacteria which releases carbon dioxide. This CO2 released from the dough gets trapped in the dough, thereby giving it a puffed appearance.

    According to Darwin's theory,natural selection refers to survival of the fittest. Example : take two beakers A and B.both had some bacteria with same environmental conditions.But after few says their environmental conditions change and the one who is capable of ACCALMATISING survives.hence,survival of the fittest

    The main function of the testes is producing and storing sperm. They're also crucial for creating testosterone and other male hormones called androgens. Testes get their ovular shape from tissues known as lobules. Lobules are made up of coiled tubes surrounded by dense connective tissues. They are typically 2 inches (5 centimeters) long, 1.2 inches (3 cm) wide and 1 inch (2.5 cm) thick. The ******* is a loose sack of skin that protects the testicles and acts as a climate control system. The testes must be at a temperature slightly cooler than the body temperature for normal sperm development.

    Chlamydia, the most prevalent bacterial STI in the United States, is the result of the Chlamydia trachomatis bacterium, which can infect the urethra (bladder opening) and cervix (uterus opening). It is common in youngsters aged fifteen to nineteen. The disease is easily treated, but like other sexually transmitted infections, chlamydia tends to be silent and therefore go undiagnosed until it becomes more serious than in its early stages. Three in four women and one in two men have no symptoms. In 40 percent of cases, by the time a girl seeks medical attention, the disease has progressed to pelvic inflammatory disease (PID, described below), a major cause of female infertility and pelvic pain.

    Gonorrhea : Chlamydia infection is sometimes confused with gonorrhea, another bacterial infection transmitted through vaginal and **** intercourse, and oral ***. Not only do they share many of the same symptoms, the two diseases can occur together.

    Gonorrhea usually begins in the urethra (bladder opening) or the cervix. However, the rapidly proliferating Neisseria gonorrhoea bacterium can migrate to the uterus and the fallopian tubes, giving rise to pelvic inflammatory disease (PID). The infection, like chlamydia, may also involve the rectum.

    It's not Tunefaciens, It's tumifaciens. Agrobacterium tumifaciens is a pathogen of several dicot plants which exhibit natural genetic engineering in plant. ✓It is able to deliver a piece of DNA called " T-DNA" to transform normal plant cell into a tumor cell. ✓The DNA transform the normal cells into tumor cells which direct them to produce the chemical essential for the pathogen.

    The large holes in ‘Swiss cheese’ are due toproduction of a large amount of CO2 by a bacterium named Propionibacterium sharmanii. The ‘Roquefort cheese’ are ripened by growing a specific fungi on them, which gives them a particular flavour.

    Nikky Saxena 6 years, 11 months ago

    The surface area of humming bird is so large as compared to volume of its body so it will lose heat more readily and fastly but generating heat for them is very expensive and time consuming process in that conditions . So the polar region is not suitable for them
