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.
Question: What is the maximum age to become an officer in the Military? Answer: By law, the maximum age for a commission is age 35. This is because a military officer must be able to have 20 years of service, to be retirement eligible by the maximum retirement age of 55. There are a few exceptions: Military medical officers and chaplains can be commissioned up to the age of 47 with waivers into their 50s (they also don't have to retire by age 55). Depending upon the need for doctors, psychologists, chaplains (all faiths), and legal officers as well, the maximum age can be waived.
