Larger eukaryotes, such as mammals, have motile cilia as well. Motile cilia are usually present on a cell's surface in large numbers and beat in coordinated waves. In humans, for example, motile cilia are found in the lining of the trachea (windpipe), where they sweep mucus and dirt out of the lungs. In female mammals, the beating of cilia in the Fallopian tubes moves the ovum from the ovary to the uterus.
Also, ask them about their basic qualifications. For example, while the basic qualifications to become a police officer in California is to be 18 years of age, other departments require a higher age limit, like 20 years of age at the time of your examinations.
Age Restrictions. The minimum age requirement has been lowered from 25 to 21. However, due to the time of hire caveat mentioned above, 18-year-olds can still apply, they just wonât be processed until they approach 21. Also, apologies to all those over the hill, but the Municipal Code of Chicago bars anyone 40 or older from being appointed as a probationary Police Officer.
