Diets high in red meat, dairy products and animal fat have frequently been implicated in the development of prostate cancer, although the data are not entirely consistent 9, Overweight, central obesity, high blood pressure, dyslipidaemia, diabetes and low cardio-respiratory fitness are among the biological factors contributing principally to increased risk. Water-soluble fibres include pectins, gums, mucilages and some hemicelluloses. Comparative International Labour Studies Pietinen P et al. The recommended levels of fruit and vegetable consumption assure an adequate intake of potassium.
Healthy or just hype?
Yes, the bob comes to rest after some time because of the resistance of the air to its motion and work done against friction at the point of oscillation O.
No, it is not a violation of the law of conservation of energy. The energy initially possessed by the bob is mostly converted to heat energy due to resistance of air and friction at point of support. Also, a small fraction of energy is also converted into sound energy.
The law of conservation of energy is not at all violated as sum total of all the energies is constant. Thus, an equivalent amount of work should be done on the body in order to bring it to rest.

In China the otter is trained to drive fish under a large net, which is then dropped and pulled in. Dependent for survival upon their ability to prey upon living animals in a variety of situations, carnivores have evolved a relatively high degree of learning ability see animal learning.
Carnivorous mammals tend to establish territories, though omnivorous carnivores, such as the black bear , striped skunk , and raccoon , are less apt to do so. Territories are often exclusive , defended by the residents against other animals of their own kind. Such areas may sometimes be marked by secretions produced by anal or other scent glands and by deposition of feces in prominent locations. There is a wide range of social patterns among carnivores.
Many bears, various foxes, genet s, most cats, and most mustelids are solitary except during the breeding season. Some remain paired throughout the year black-backed jackal and lesser panda or occasionally roam in pairs gray fox , crab-eating fox , and kinkajou. Other carnivores, such as the wolf , African hunting dog , dhole , and coati , normally hunt in packs or bands. Various pinniped s form sedentary colonies during the breeding season, sea otters congregate during a somewhat larger part of the year, and meerkat s are permanently colonial.
Mating systems vary among families, ranging from monogamy in the wolf and polygyny in most bears and mustelids to harems in elephant seal s. Copulation is vigorous and frequent in many species, including the lion, and many species possess reproductive peculiarities as adaptations to their environments.
Induced ovulation, for instance, allows females to release egg cells during or shortly after copulation. Delayed implantation of the fertilized egg in the wall of the uterus is another phenomenon that allows births to occur when resources are abundant. This phenomenon is most prominent in species living in highly seasonal environments. Delayed implantation is most extreme in the pinnipeds and bears but is absent from canines. The smallest living member of Carnivora is the least weasel Mustela nivalis , which weighs only 25 grams 0.
The largest terrestrial form is the Kodiak bear Ursus arctos middendorffi , an Alaskan grizzly bear that is even larger than the polar bear Ursus maritimus. The largest aquatic form is the elephant seal Mirounga leonina , which may weigh 3, kg 8, pounds. Most carnivores weigh between 4 and 8 kg 9 and 18 pounds. The vast majority of species are terrestrial, but the pinnipeds are highly adapted to life in the water.
Some nonpinnipeds, such as the sea otter , are almost fully aquatic, while others, such as the river otter and polar bear, are semiaquatic, spending most of their lives in or near water. Aquatic and semiaquatic forms have developed specializations such as streamlined bodies and webbed feet.
Carnivores, like other mammals, possess a number of different kinds of teeth: Most carnivores have carnassial, or shearing, teeth that function in slicing meat and cutting tough sinews. The carnassials are usually formed by the fourth upper premolar and the first lower molar, working one against the other with a scissorlike action.
Cats, hyenas, and weasels, all highly carnivorous, have well-developed carnassials. Bears and procyonids except the olingo , which tend to be omnivorous, and seals, which eat fish or marine invertebrates, have little or no modification of these teeth for shearing.
The teeth behind the carnassials tend to be lost or reduced in size in highly carnivorous species. Most members of the order have six prominent incisors on both the upper and lower jaw, two canines on each jaw, six to eight premolars, and four molars above and four to six molars below. Incisors are adapted for nipping off flesh. The outermost incisors are usually larger than the inner ones. The strong canines are usually large, pointed, and adapted to aid in the stabbing of prey.
The premolars always have sharply pointed cusps, and in some forms e. Except for the carnassials, molars tend to be flat teeth utilized for crushing. Terrestrial carnivores that depend largely on meat tend to have fewer teeth 30—34 , the flat molars having been lost.
Omnivorous carnivores, such as raccoons and bears, have more teeth 40— Pinnipeds have fewer teeth than terrestrial carnivores. In addition, pinnipeds exhibit little stability in number of teeth; for example, a walrus may have from 18 to 24 teeth. Several features of the skeleton are characteristic of the order Carnivora. Articulating surfaces condyles on the lower jaw form a half-cylindrical hinge that allows the jaw to move only in a vertical plane and with considerable strength. The clavicles collarbones are either reduced or absent entirely and, if present, are usually embedded in muscles without articulation with other bones.
This allows for a greater flexibility in the shoulder area and prevents breakage of the clavicles when the animal springs on its prey. The brain is large in relation to the weight of the body, and it contains complex convolutions characteristic of highly intelligent animals. The stomach is simple as opposed to multichambered, and a blind pouch cecum attached to the intestine is usually reduced or absent. The teats are located on the abdomen along two primitive lines milk ridges , a characteristic of mammals that lie down when nursing.
Many carnivores have a well-developed penis bone, or baculum. It appears that this structure plays a role in helping to increase the success of copulation and fertilization of eggs in species where numerous males mate with a single female. Cats have a vestigial baculum or none at all, but the baculum of the walrus can measure up to 54 cm 21 inches. Carnivores are found worldwide, although Australia has no native terrestrial members except for the dingo , which was introduced by aboriginal man.
Terrestrial forms are naturally absent from most oceanic islands , though the coastlines are usually visited by seals. However, people have taken their pets, as well as a number of wild species, to most islands. For example, a large population of red foxes now inhabits Australia, having been introduced there by foxhunters. Introduction of carnivores to new environments has at times devastated native fauna. In New Zealand , stoats, ferret s and weasel s were introduced to control rabbits, which had also been introduced.
