Answer:
Centrifugation.
Explanation:
When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation.
Centrifugation can be defined as the process of separating particles from a liquid solution according to density, shape, size, viscosity through the use of a centrifugal force. In order to separate these particles, the particles are poured into a liquid and placed in a centrifuge tube. A centrifuge is an electronic device used for the separation of particles in liquid through the application of centrifugal force. Once the centrifuge tube is mounted on the rotor of the centrifuge, it is spun rapidly at a specific speed thereby separating the solution; denser particles are forced to the bottom (by moving outward in the radial direction) and the lighter particles stay at the top as a result of their low density.
Answer:
def leap_year_check(year):
return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)
Explanation:
The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.
int ensures the argument is read as an integer and not a float.
The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.
If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)
the function leap_year_check returns a boolean ; true and false if otherwise.
The correct answer for this question is this one: " c.huge initial investment"

Answer:
Priming.
Explanation:
The brain is the centre of control for all animals. It coordinates the body system, breathing, beating of the heart, memory, gait, speech, sight etc.
Memory is stored in the brain ( the function of the cerebral cortex in the cerebrum). Two types of memory are the long term and the short term memory. The long term memory stores information permanently in the brain, while the short term holds the information for a while and either transfers it to the long term memory or the memory decays.
To retrieve a specific memory from the wide memory of the brain, it activates a strand that leads to the memory, this process is called priming.
Answer: Computer operator
Explanation:
Following the information given, we can deduce that Connie is employed as a computer operator. A computer operator is a role in IT whereby the person involved oversees how the computer systems are run and also ensures that the computers and the machines are running properly.
Since Connie keeps the operating systems up-to-date, ensures that memory and disk storage are available, and oversees the physical environment of the computer, then she performs the role of a computer operator.
