Predators

agriculture. Such species loss, whether of wild or farmed organisms, is increasingly seen as a cause for concern. Not only may there be risks associated with dependence on too small a range of genetic types, should they become subject to some disease or predator, but the loss of genetic variety may deprive society of the opportunity to make full use of developments in genetic science. These relate not only to production but also to the development of pharmaceuticals and health related products. Possible

It’s often men who seem to be beyond suspicion who turn out to be the worst predators. They don’t all have greasy hair and dirty raincoats, you know. 22 Livre du professeur New On Target Term © BELIN 2012 Help on important words, important questions (p. 35) Corrigé – Sergeant Jim Smyth/Smith (a policeman) – Russell Williams,

adapt to their environment and to recreate themselves and their environment. Plants and animals, microbes and bacteria, and cells and their nuclei have developed sophisticated defenses (disguises, antibodies, toxins, mutating processes) against predators and threats in their environments. While it may take them somewhat longer to solve their problems, given a million years or so, they manage. This is not to say that there are no mistakes along the way. The mammalian immune system sometimes gets a

During the tour of my house, Frankie shadowed Saint Rebecca, avoiding me like I was a large, unpredictable predator. When it became clear that she was about to take off without him, he looked at her piteously, silently imploring, “Don’t leave me here. She’s clueless.” Nor did things improve soon. For the first few days, Frankie lay on the couch, languishing

This initial physiological response is followed by a slower, more detailed psychological assessment and emotional experience, during which we become conscious of feeling afraid—thinking fearful thoughts, worrying, feeling scared, or sometimes pretending

They reduced the odds that a predator would take us by surprise or that we’d overlook a nearby source of food. For most of history, the normal path of human thought was anything but linear. To read a book was to practice an unnatural process of thought, one that demanded sustained, unbroken

There’d be more lions where the gazelles crowded around the watering hole. Fewer prey animals, fewer predators. “How does the business of—well, of Amun, say—get conducted between those biennial meetings?” There had to be stuff that came up. “Message boards, mostly.
