Unit 0 Lesson 2 Quiz

How many other neurons can a single neuron connect to?

• Up to 10

• Up to 100

• Up to 10,000

• Up to 1,000,000

Answer explanation

A single neuron can connect to up to 10,000 other neurons, allowing for complex networks and communication within the brain. This high connectivity is crucial for processing and transmitting information.

What is a stressor in the context of antifragility?

• Anything that damages a system permanently

• Anything that pushes a system slightly past its limits

• Anything that helps maintain the status quo

• Anything that prevents growth

Answer explanation

In antifragility, a stressor is anything that pushes a system slightly past its limits, allowing it to adapt and grow stronger. This contrasts with options that imply damage or stagnation.

What system is responsible for controlling the body and mind through electrical signals?

• The digestive system

• The cardiovascular system

• The nervous system

• The immune system

Answer explanation

The nervous system is responsible for controlling the body and mind through electrical signals, coordinating actions and responses to stimuli, unlike the digestive, cardiovascular, or immune systems.

Which mindset believes that intelligence and abilities are capped or limited?

• Fixed mindset

• Growth mindset

• Unchangeable mindset

• Passive mindset

Answer explanation

The fixed mindset is the belief that intelligence and abilities are static and cannot be changed. In contrast, a growth mindset embraces the idea that skills can be developed through effort and learning.

What effect does experience have on the nervous system?

• No impact on neural connections

• Permanent weakening of connections

• Physical changes, including the formation of new connections

• Complete preservation of the original structure

Answer explanation

Experience leads to physical changes in the nervous system, including the formation of new neural connections. This adaptability, known as neuroplasticity, allows the brain to reorganize itself based on learning and experience.

What is a key trait of individuals with a growth mindset?

• They avoid challenging tasks

• They view failure as proof of their limits

• They believe effort can improve their abilities

• They assume abilities are determined by genetics alone

Answer explanation

A key trait of individuals with a growth mindset is their belief that effort can improve their abilities. This perspective encourages them to embrace challenges and view failures as opportunities for growth.

What is learning defined as in the text?

• Acquiring physical strength

• Developing new habits

• The process of acquiring new understanding, knowledge, skills, or behaviors

• Increasing brain size

Answer explanation

How do people with a fixed mindset view challenges?

• They avoid them

• They seek them out

• They enjoy them

• They are indifferent to them

Answer explanation

People with a fixed mindset view challenges as threats to their abilities, leading them to avoid them. They fear failure and believe that effort won't change their inherent skills.

How many other neurons can one neuron connect to?

• 100

• 1,000

• 10,000

• 100,000

Answer explanation

A single neuron can connect to approximately 10,000 other neurons, forming a complex network that facilitates communication within the brain. This high connectivity is crucial for processing and transmitting information.

What belief about the brain did scientists hold until the 1980s and 1990s that we now know is false?

• The brain continues to grow throughout life

• The brain stops developing after childhood

• The brain's connections can get stronger and weaker

• The neurons of the brain don't connect to any other cells

Answer explanation

Until the 1980s and 1990s, scientists believed that the brain stops developing after childhood. However, research has shown that the brain continues to grow and change throughout life, particularly in response to experiences.
