Q: Using at least two pieces of scientific evidence, construct an argument that supports the claim that some microorganisms are beneficial to human health.
Q: Using at least two pieces of scientific evidence, construct an argument that supports the claim that some microorganisms are beneficial to human health.:
A: Many microorganisms are essential to human health. For example, gut bacteria like Bifidobacterium help digest food and produce vitamins such as B12. Studies show that probiotics can improve digestion and strengthen the immune system. Therefore, not all microorganisms are harmful; some are vital for our well-being.
Why do animals need both instincts and learned behaviors to survive in their environment?
Why do animals need both instincts and learned behaviors to survive in their environment?
Animals need instincts to do important things like breathing, hiding from predators, or finding food right after birth. They need learned behaviors to adapt to new environments or situations—for example, a bear learning which areas have the most food.
What is a chemical change
What is a chemical change:creates a new substance
How can a magnetic field be generated from an electric current?
How can a magnetic field be generated from an electric current?:A magnetic field can be generated from an electric current by passing the current through a conductor
How do destructive forces affect landforms
How do destructive forces affect landforms:They wear down or break apart existing landforms.
Q: Design an investigation or report analyzing a real-world outbreak (e.g., E. coli, influenza, COVID-19), using scientific data to show how harmful microorganisms spread and affected people.
Q: Design an investigation or report analyzing a real-world outbreak (e.g., E. coli, influenza, COVID-19), using scientific data to show how harmful microorganisms spread and affected people.:
A: [Sample summary] A report on the 2011 E. coli outbreak in Europe could describe how contaminated sprouts caused over 4,000 illnesses and 50 deaths. The investigation would include transmission pathways, incubation period, and response efforts. Scientific data such as infection rates, genome sequencing of the bacteria, and containment strategies would support the argument that harmful microorganisms pose a serious threat.
How is an inherited trait different from an acquired trait? Can you give an example of each?
How is an inherited trait different from an acquired trait? Can you give an example of each?
Inherited traits come from your parents and are present at birth. Acquired traits are gained after birth through experience or environment.
Give me an example of a chemical change
Give me an example of a chemical change:burning wood
What is the relationship between electric current and magnetic fields?
What is the relationship between electric current and magnetic fields?:Moving electric charges create magnetic fields
Compare and contrast the ways in which constructive and destructive forces shape Earth's surface. Provide specific examples of each.
Compare and contrast the ways in which constructive and destructive forces shape Earth's surface:Constructive forces, like volcanic eruptions and sedimentation, build up landforms, while destructive forces, such as weathering and erosion, break them down
Q: Evaluate the role of bacteria in the human digestive system and argue whether their presence is more helpful or harmful.
Q: Evaluate the role of bacteria in the human digestive system and argue whether their presence is more helpful or harmful:
A: Bacteria in the digestive system, such as Lactobacillus and Bacteroides, help break down complex food molecules and produce essential nutrients. Though some bacteria can cause infections, the overall presence of gut microbiota is helpful because they support digestion, immune function, and even mental health through the gut-brain axis.
Why is it important to understand the difference between inherited and acquired traits when learning about how living things grow and change?
Why is it important to understand the difference between inherited and acquired traits when learning about how living things grow and change?
Answer:
Understanding the difference helps us know what traits we’re born with and what traits can change over time. This is important in science and health—like knowing if a disease runs in a family (inherited) or came from a person’s lifestyle (acquired). It also helps us see how organisms adapt to their environments.
what is a physical change
what is a physical change:a transformation that alters the appearance or state of a substance
Question: What are the two poles of a magnet called?
Question: What are the two poles of a magnet called?:North and South poles
Given a specific landform, such as a delta or a sand dune, analyze the processes that contributed to its formation. What evidence supports whether it was created by constructive or destructive forces?
Given a specific landform, such as a delta or a sand dune, analyze the processes that contributed to its formation. What evidence supports whether it was created by constructive or destructive forces?:It is formed by deposition because it is a build up of dirt and sediment from a river that connects to the ocean

What is one way that an instinct is different from a learned behavior? What is one way they are similar?
What is one way that an instinct is different from a learned behavior? What is one way they are similar?
✅ Answer:
Different: Instincts happen without teaching, but learned behaviors require training or experience.
Similar: Both are behavior patterns that help animals survive and adapt to their environment.
.
what are the three states of matter
what are the three states of matter:Liquid solid gas
What happens when you bring the North pole of one magnet near the South pole of another magnet?
What happens when you bring the North pole of one magnet near the South pole of another magnet?:They attract each other.
What is the difference between a constructive and destructive force in terms of how they affect the Earth's surface?
What is the difference between a constructive and destructive force in terms of how they affect the Earth's surface?:Constructive forces build up landforms, while destructive forces wear down landforms.
Q: Using scientific evidence, construct an argument that supports the claim that some microorganisms are harmful to humans
Q: Using scientific evidence, construct an argument that supports the claim that some microorganisms are harmful to humans
A: Some microorganisms cause serious diseases in humans. For example, the influenza virus spreads through the air and causes seasonal flu, which can lead to hospitalization or death. Escherichia coli (certain strains) can contaminate food and cause severe stomach illness. According to the CDC, foodborne illnesses affect 48 million people in the U.S. each year. This evidence supports the claim that some microorganisms are harmful.
What is an instinct? What is a learned behavior?
What is an instinct? What is a learned behavior?
✅ Answer:
An instinct is a behavior an animal is born with. It happens automatically and doesn’t need to be taught.
Example: A turtle going to the ocean right after hatching.
A learned behavior is something an animal learns by watching, practicing, or being taught.
Example: A dog learning to sit when given a treat.
