问题 解答题

丰富的生物资源与人类的生存和可持续发展有密切的关系.______.(判断对错)

答案

生物多样性通常有三个主要的内涵,即生物种类的多样性、基因(遗传)的多样性和生态系统的多样性.生物圈的资源、空间是有限的,人类要合理开发利用自然资源,保持自然资源的可持续发展.现在随着人类活动的加剧、环境的破坏等因素的影响,生物的多样性面临着严重的威胁.因此我们要注意保护生物的多样性,合理的开发和利用生物资源,与人类的生存和可持续发展有密切的关系,故题干动物说法正确.

故答案为:√

People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.

However, Dr. Michael A.McDaniel emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “ not particularly large,” McDaniel noted “ There’s some relationship between brain size and intelligence on average, but there’s plenty of room for exceptions,” he said.

Interest in the relationship between brain size and intelligence grew in the 1830s, when German anantomist(解剖学家)Frederick Tidemann wrote that he believed there was “ a natural connection between the size of the brain and the mental energy displayed by the individual man.” Since that statement, scientists have conducted numerous studies to determine if Tidemann’s idea was , in fact, correct. Most studies have investigated the link between head size and intelligence .More recently, however, researchers have published additional studies on intelligence and brain size, measure using MRI scans.

For his study, McDaniel analyzed more than 20 studies that investigated the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on average, people with larger brain volume tended to be more intelligent. The relationship was stronger in women that men, and adults than children ,McDaniel noted.

In an interview, McDaniel noted that he’s not sure why the relationship was stronger for adults and women. Previous research has shown that women, on average, tend to have smaller brains that men, but score just as well--- if not higher--- in tests of intelligence he said.

McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-brained people who are highly intelligent,” he said” But , on average, the relationship holds.”
