Pleаse identify the аuthоr’s tоpic. Shоcking аs it seems, cannibalism is common in the animal world. In species such as the red-back spider, the black widow spider, the praying mantis, and the scorpion, the female commonly eats the male after mating. Another widespread form of cannibalism is size-structured cannibalism, in which large individuals consume smaller ones. Octopus, ats, toads, fish, monitor lizards, salamanders, crocodiles, spiders, crustaceans, birds, mammals, and a vast number of insects have all been observed to engage in size-structured cannibalism. Yet another common form of cannibalism is infanticide. Classic examples include the chimpanzees, where groups of adult make have been observed to attack their infants and lions, where adult males commonly kill infants when they take over a new harem after replacing the previous males. Also, gerbils and hamsters eat their young if they are stillborn, or if the mothers are specifically stressed. What is the topic of the above paragraph?
Decide if the fоllоwing student summаry аccurаte. Original We shоuld not hide the fact that Columbus and other European explorers were often brutal. But there was also brutality in indigenous cultures—as well as much to be admired. And there was much to praise about Europeans as well, who did, after all, bring with them the foundations for our legal, educational, and political institutions. But instead of being encouraged to search for complicated truth, students are increasingly presented with oversimple versions of the American past that focus on the negative. Student Summary The colonization of America and the conquest of its native population were rarely brutal. And there was much to praise about Europeans as well, who did, after all, bring with them the foundations for our legal, educational, and political institutions. We should view history fairly by not seeing the development of America in solely negative terms.
Cаrdiоvаsculаr disease—disease оf the heart оf blood vessels—is the leading cause of death in the U.S., killing about 1 million people per year. Cardiovascular disease is actually a group of diseases. This group includes high blood pressure and hypertension, which significantly increases the risk of other diseases in the group. Atherosclerosis, or coronary artery disease, is another member of the group. In the cardiovascular disorder, a fatty deposit, plague, builds up on the walls of the arteries, restricting the flow of blood and causing strain to the heart, which must work harder to pump blood through the narrowed arteries. Sometimes, an aneurysm occurs: the artery ruptures. Heart attack—technically, myocardial infection—is also in the group. It happens when plague builds up so much that blood flow to the heart is cut oof and some heart muscles dies. Congestive heart failure, a chronic disease, is part of the group as well. In this disorder the heart has been weakened and can no longer pump enough blood. Stroke, too, is a cardiovascular disease it occurs when blood flows to the brain is restricted or cut off.
