Primo de Rivera's Dictatorship (1923-1930)

In 1923, General Primo de Rivera organised a military coup with the king's consent and the support of certain sections of the high bourgeoisie and conservative politicians.

Cell Membrane Structure and Function

Question: What is the role of organic molecules in the cell membrane?

Answer: Organic molecules contribute to cell–cell adhesion and protect the cell surface from chemical damage.

How Are Substances Transported Across the Membrane?

There are three main types of membrane transport:

• Passive transport — a type of membrane transport that does not require energy to move substances across cell membranes. Passive transport can use diffusion or osmosis and depends on the concentration gradient.
• Facilitated transport — molecules are transported across the plasma membrane with the help of membrane proteins (examples in common descriptions include oxygen, CO2, and glucose).
• Active transport — uses different protein

Statistics Problems and Solutions

Great! Let's continue with providing solutions to the questions:

Question 1: Empirical Rule Name

The Empirical Rule is also known as:

• E. The 68–95–99.7 Rule

Question 2: Normal Distribution Interval (95%)

For a normally distributed data set with a mean of 70 and a standard deviation of 13, approximately 95% of the data lie within about two standard deviations of the mean.

• Calculate: 70 ± 2 × 13 = 70 ± 26
• Result: 44 and 96

Question 3: Mean and Median for the Set

For the set of numbers: 27, 83, 55, 61, 102, 17:

• a) Mean — Add all the numbers together and divide by the count (6):
• Sum = 27 + 83 + 55 + 61 + 102 + 17 = 345
• Mean = 345 / 6 = 57.5
• b) Median — Arrange in ascending order and take the middle value (or average
