The <u>type 2</u> slowly changing dimension approach creates a new additional dimension record using a new value for the surrogate key every time a value in a dimension record changes. The correct answer is B.
<h3>Understanding the Slowly Changing Dimension</h3>
SCD, or slowly changing dimension, can be defined as a dimension in a data warehouse that stores and maintains the current data and the historical data over time. A slowly changing dimension in a star schema contains two different attributes values: do not change and change occasionally. Here is the difference:
- Attributes whose values do not change (or change very infrequently), including such store size and client gender.
- Attributes whose values vary intermittently and irregularly throughout time, such as customer zip code and staff salary.
The three most common approaches for coping with slowly changing dimensions are as follows:
Whenever a value in a dimension record changes, type 2 of a slowly changing dimension produces a new extra dimension record with a new value for the surrogate key. This type is also utilized when history needs to be kept, and it may be paired with the usage of timestamps and row indications.

Congestive heart failure's life expectancy is influenced by the underlying medical disorders, the heart failure's severity, and its origin.
<h3>What is meant by congestive heart failure?</h3>
When the heart muscle is unable to pump blood as effectively as it should, heart failure, sometimes referred to as congestive heart failure, occurs. Shortness of breath is frequently brought on by this because blood frequently backs up and fluid can accumulate in the lungs.
Congestive heart failure's life expectancy is influenced by the underlying medical disorders, the heart failure's severity, and its origin. The average five-year survival rate for those who are diagnosed with congestive heart failure is around 50%. 30% of people will live for ten years.
Heart failure, also known as congestive heart failure, is a dangerous disorder when the heart is unable to pump blood as effectively as it should. Contrary to its name, heart failure doesn't indicate that the heart has actually stopped beating or is soon to do so.

Soft palate
The soft palate is composed of muscle and connective tissue, which give it both mobility and support. This palate is very flexible. When elevated for swallowing and sucking, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx.

Answer:
The correct answer will be option B.
Explanation:
Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.
Thus, option B is the correct answer.
