motility
To determine the probability of 15 random people all having the same birthday, consider each person one at a time. (This is for the non leap-year case.)The probability of any person having any birthday is 365 in 365, or 1.The probability of any other person having that same birthday is 1 in 365, or 0.00274.The probability, then, of 15 random people having the same birthday is the product of these probabilities, or 0.0027414 times 1, or 1.34x10-36.Note: This answer assumes also that the distribution of birthdays for a large group of people in uniformly random over the 365 days of the year. That is probably not actually true. There are several non-random points of conception, some of which are spring, Valentine's day, and Christmas, depending of culture and religion. That makes the point of birth, nine months later, also be non-uniform, so that can skew the results.
Continous Culture The notion continuitity is virtual, everything in nature is discrete. Also cultures are discrete and change in stepsm Most frequently in semi continuous steps, but sometimes in HUGE leaps (paradigm shifts)
In 2009, the ministry of Tourism and Culture counted 282 874 visitors in the Yukon.
the amount of virus required to kill 50% of infected host or to produce cytopathic effect in 50% of inoculated tissue culture cells
The one child policy was established in the 1970's in order to control a rapidly growing Chinese population. This resulted in heavy discrimination and violence against girls and women. Because Chinese culture prizes male children as the continuum of family bloodlines, a custom of killing baby girls through either infanticide or abortion became increasingly common. The development of ultrasounds, that allow the sex of an unborn child to be determined have promoted instances of sex-selective abortion, where a fetus is aborted if it happens to be female. This has caused a wide gap in the gender ratio of Chinese people. The current statistic is 119 males to every 100 females.
it depends on the bacterial capsule, some grows on glucose, some grow on carbondioxide and low iron(LIM culture).
Pure broth culture is a liquid media, used to propagate large numbers of microorganisms. Where as Slant cultures are semi solid media containing a solidifying agent (usually agar). Can be used in determining bacterial motility and in promoting anaerobic growth.
The metabolism of the peptides (as the baterial culture uses them) causes the production of ammonia, which increases the pH.
Bacterial culture. Fungal culture. Viral culture
Older cultures tend to become non-motil after a while. Since an old culture will produce acid in its media, most of the flagella will be lost. By using young cultures you will have motile organisms. If you have more questions about the details, look online or in a micro book, you will find it.

A bacterial culture containing a single species of organism is referred to as pure or axenic.

Are you in Dr. Johnson's class? :)
It's a bacterial culture.
Yes it is. The bacterial culture is the same.
yes.
