What Is the Consumer Price Index – CPI?


The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them. Changes in the CPI are used to assess price changes associated with the cost of living; the CPI is one of the most frequently used statistics for identifying periods of inflation or deflation.

What is a period and why do we have them?

A period is when a woman’s body releases tissue it no longer needs. This tissue comes from the uterus, which is where a baby (fetus) can develop in the female body. Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn’t get fertilized, that lining is released from the body as blood through the vagina. This monthly process is called menstruation or a period.So when a girl has her period, her body is just getting rid of a small amount of blood and some unneeded tissue. It is a natural, normal body process for all females as they become women and mature physically.

What is “CRISPR”?

“CRISPR” (pronounced “crisper”) stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term “CRISPR” or “CRISPR-Cas9” is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools.

What is the concept of Space?

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is, often conceived in three linear dimensions, although modern physicists, usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.

The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
