Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age. People will be alert and receptive if they are faced with information that gets them to think about things they are interested in.

The research published in the British Journal of Cancer backs up a 1988 theory that some as-yet unidentified infection caused leukaemia—not the environmental factors widely blamed for the disease. "Childhood leukaemia appears to be an unusual result of a common infection," said Sir Richard Doll, an internationally-known cancer expert who first linked tobacco with lung cancer in 1950. "A, virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection.

Evidence is accumulating, though the research is still in its very early phases, that the periods before and soon after birth, childhood and early adolescence are much more important to breast cancer risk than had been appreciated. Just as heart disease has its origins in childhood, breast cancer is not just an adult disease. For example, there is a strong link between high-fat diets in the population and high rates of breast cancer, but at best a weak relationship to the amount of fat an individual woman consumes as an adult. But the effects of fat in a child’ s diet may explain why Japanese women who emigrate to the United States maintain their l A. because of Americans’ diet, people there, including immigrants, have a high risk of breast cancer. B. an adult woman’ s intake of high-fat diets has little to do with her risk of breast cancer. C. American white women have a higher risk of breast cancer than women with darker skins. D. Asian immigrants’ daughters and granddaughters brought up in the U.S. have a higher risk of breast cancer than their mothers and grandmothers. 查看答案 [单项选择] {{B}}TEXT D{{/B}} Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively areas such as attention and memory.

It is known that the brain shrinks as the body ages, but the effects on mental ability are different from person to person. Interestingly, in a study of elderly men and women, those who had more education actually had more brain shrinkage. "That may seem like bad news," said study author Dr. Edward Coffey, a professor of psychiatry and of neurology at Henry Ford Health System in Detroit. However, he explained, the finding suggests that education allows people to withstand more brain-tissue loss before their mental functioning begins to break down. The study, published in the July issue of Neurology, is the first to provide biologica A. enhance mental development B. protect the brain from mental decline C. prevent the brain from shrinking D. compensate for brain shrinkage 查看答案 我来回答: 提交 最新试题 ●    [单选题]动火执行人应具备有关部门颁发的( )。 ●    [单选题]建筑高度超过()m 的教学楼是一类高层建筑。 ●    [单选题]蛋白质结构中的α--螺旋属于: ●    [判断题]转点是用来传递高程的、在转点上不应放尺垫。( ) ●    [判断题]通信线路、漏泄电缆和通信杆的维护实行维修、中修、大修修程，其他通信设备的维护实行维修修程。 ●    [判断题]要求司机鸣笛信号：昼间——拢起的手信号旗直立平举或单臂向上弯曲直立上下小动。 网站地图 我要搜题网  版权所有  ©2024  湘ICP备18016427号   购买搜题卡查看答案 [会员特权] 开通VIP， 查看 全部题目答案 [会员特权] 享免全部广告特权 推荐91天 ¥36.8 ￥80元 31天 ¥20.8 ￥40元 365天 ¥88.8 ￥188元 请选择支付方式 微信支付 支付宝支付 点击支付即表示同意并接受了《购买须知》 立即支付 系统将自动为您注册账号 已有账号登录 找回账号密码 请使用微信扫码支付 订单号： 截图扫码使用小程序[完全免费查看答案] 前往小程序 请不要关闭本页面，支付完成后请点击【支付完成】按钮 支付完成 取消支付 恭喜您，购买搜题卡成功 系统为您生成的账号密码如下： 账号 密码 重要提示：请拍照或截图保存账号密码！ 我要搜题网官网：https://www.woyaosouti.com 我已记住账号密码
