Reflection and Unit 1 Mock Review

WALT: Reflect on our

performance in semester 1 and set goals for semester 2

Do Now: If you were to give yourself a grade for your effort in Biology for the fall semester, what would it be? Why?

Reflection

● Tape/glue your semester report in your notebooks

and then answer the following questions.
○

What is one topic in Biology that you feel you understood
well this semester? Why do you think you were successful
with it?

○

What category did you do the best in? What did you do the worst in?

○

Goal Setting

● What grade do you want for the

Spring Semester?

● What are 3 steps you will take to

achieve your goal?

Unit 1 Mock Test Review

Key Concepts

●Our body systems work together to maintain homeostasis. Certain things
disrupt homeostasis which make us sick.

●Homeostasis is maintained through negative feedback loops (these stop
or reverse an action). Positive feedback loops encourage an action to
continue.

●Experimental design: Control vs experimental groups, reading tables,
making/supporting/refuting claims, providing evidence and reasoning.

Match

Match the following body systems with its function

• Circulatory System

• Digestive System

• Respiratory System

• Nervous System

• Excretory System

Transports blood and nutrients

Breaks down food for energy

Facilitates gas exchange

Controls body functions and movements

Removes waste products

• Transports blood and nutrients

• Breaks down food for energy

• Facilitates gas exchange

• Controls body functions and movements

• Removes waste products

Multiple Choice

Homeostasis in the human body is often maintained by a: 

• the brain only

• solar feedback loop
• the muscles

• negative feedback loop

Word Cloud

what 1-2 words come to mind when you hear homeostasis?

Multiple Select

Which of the following terms are synonyms (the same) for homeostasis? Select all that apply.

• Dynamic Equilibrium

• Internal balance

• Maintained stability

• Disruption

• Disorder

Multiple Choice

Failure to maintain homeostasis could result in:

• lack of internal balance
• eventual death
• difficulty carrying on metabolism 
• all three

Multiple Choice

What is the point of a feedback loop?

• To provide the body with more energy

• To provide the body with more food

• To make sure the conditions in the body are always changing

• To make sure the conditions in the body remain stable

Multiple Choice

Loops that slow or stop or inhibit an action are called _____________ feedback loops.

• positive

• negative

Multiple Choice

Loops that cause a response to build up and build up until something big happens are called ____________ feedback loops

• positive

• negative

Multiple Choice

What type of feedback system does the model represent?

• negative

• neutral

• positive

• glycogen

Multiple Choice

What type of feedback loop is shown?

• negative
• neutral 
• positive

Multiple Choice

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

Multiple Choice

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.

• Positive Feedback Response
• Negative Feedback Loop

Multiple Choice

What do the words efficient and sufficient mean in this question?

• Efficient: completing something as quickly as possible.

  Sufficient: having just enough resources to get by

• Efficient: doing something in the best or most productive way.

  Sufficient: having enough of something to meet a need.

• Efficient: doing something poorly but quickly.

  Sufficient: doing something in the best or most productive way.

• Efficient and sufficient both mean achieving a goal with minimal effort.

Multiple Choice

Which of these choices would be the best question for an experiment that wants to test Iguana salt glands is able to keep them alive in changing environments?

• 1

• 2

• 3

• 4

Open Ended

In your own words describe the difference between between the control group and experimental group in this experiment.

Poll

Are there significant differences between these 2 groups

• Yes

• No

• Not sure

Multiple Choice

What is the correct answer choice

• 1

• 2

• 3

• 4

Multiple Choice

According to the text, Iguanas are able to expel (get rid of) excess salt through sneezing it out their salt glands. This helps them maintain the level of salt the need in their body. This is an example of...

• Positive feedback

• Negative feedback

Hotspot

Point to the 2 BEST pieces of evidence that supports the idea that "expelling excess salt from glands" is a negative feedback loop.
