Один биолог открыл удивительную разновидность амеб. Каждая из них через 1 инуту делилась на две. Биолог в пробирку кладет амебу, и ровно через 1 час она оказывается заполненной амебами. Сколько времени потребуется, чтобы вся пробирка заполнилась амебами, если в нее в начале положить не одну, а две амебы?

Ответы

Автор ответа: Аноним

59 минут (на одну минуту меньше, поскольку амёб на 1 больше)

An Autobiography

By Erika Baker

My name is Erika Baker. I was born on June 15, 2002, in Sarasota, Florida. I still live in Sarasota, Florida, and study at Booker High School. I live with my father, Mr Christopher Baker; my mum, Mrs Katherine Baker; my brother, Jake; and my Aunt Molly.

Who I am in life

I started school when I was six years old. I went to a kindergarten through the fifth form at Booker Elementary. While I was there, I won an award for perfect attendance. I also won an award for honour roll all four terms. Then I attended Booker Middle School. There the School Administration Board awarded me with a couple of certificates, too: one for perfect attendance and two for being named the Best Student of the Year one in the sixth form and the other in the eighth form. I am now a senior at Booker High School. After finishing school I plan to continue my education in a community college.

What life means to me

Life to me means friends and family who you can trust to and who trusts you. I am pretty much on the happy side of life, but like all teens I have my “days off”. That means I have some sad days or depressed days. I have a few close friends in my school and when I am having a bad day, I have someone to talk to. My friends say that I’m honest, reliable and well-wishing. I make my school days go by trying hard to get good marks at school. I always spend a lot of time with my friends at the weekend. Our favourite places to go are the local park and the cinema. I don’t want to become a professional sportsman, but I enjoy swimming and gymnastics. I’m interested in music and modern dancing.

What’s my outlook on the future

In ten years time I think I will probably be still living here in Sarasota. I will be quite comfortable with my living situation, meaning that I will have my university diploma. I’ll start working, or will run my own business. I’ll be married. Probably, I’ll have a child. I hope that I’ll be happy.

Conclusion

As I’ve mentioned before, I was born here in Florida and I’ve lived here my whole life.

I would like to see more of the USA and other countries. I want to find good friends around the world. I hope that my knowledge and persistence will help me to succeed in life.

My motto is: “What you dream about, can be easily done. Just do it.”
