Автор ответа: ybya

Паразиты, развивающиеся только в одном хозяине, называются: b. Строгоспецифичные . ---- например (лямблии, токсоплазмы, трихомонады)

биогельминты-- это паразиты со сменой хозяев (бычий цепень , печеночный сосальщик) ---этот ответ не подходит

гиперпаразиты- это паразиты обитающие на паразитах (некоторые паразиты насекомых обитают на личинках некоторых видов бабочек --этот ответ не подходит.

Hitting the $100,000 salary mark is the dream of a lot of people. And it's a dream that doesn't
come true for many, not with average household income which is usually under $52,000 in the
U.S. That's down from a peak of $56,800 in 2000, due to inflation.
But there are plenty of jobs where that salary level is the norm. A handful of those unusual jobs
doesn't keep you in office all day working with numbers. Fewer still are the jobs that are
interesting and don't require advanced degrees.
We turned to 2012 figures (the latest data available) from the Bureau of Labor Statistics to
identify unusual jobs that earn at least $100,000 a year.
This isn't one of those easy professions you can get with just a bachelor's degree. An
astronomy job usually requires an advanced degree, but the payoff is handsome. The usual
annual wage for astronomers was about $96,000 in 2012, but those who were lucky enough to
work for the federal government, took home in general $139,000 a year.
There is one downside to the job. Astronomers may need to work at night, since there is less
radiation from the sun to mess with their observations then. But most astronomers work normal
office hours and only visit observatories a few times a year.
Another rare job is an air traffic controller. The stress from this job is one reason that the pay is
so high. Air traffic controllers are also needed at night and on the weekends. The level of
education needed isn't high; controllers need to complete a training course at a Federal Aviation
Administration Academy.
Because this job can be stressful, controllers often retire earlier than other workers. Those who
have worked 20 years in this post are able to retire at 50, but they are required to retire at the
age of fifty six.
1 A lot of people would like to earn $100,000.
2 Americans usually earn not more than $52,000.
3 There are a few jobs where you can earn $100,000.
4 Few jobs with a high salary demand an advanced level of education.
5 The Bureau of Labor Statistics is situated in NY.
6 An astronomy job gives a chance to earn a lot.
7 The federal government pays all the astronomers.
8 Astronomers have to work at night.
9 An air traffic controller is a very stressful job.
10An air traffic controller usually retires at the age of 50.
