Q

How do oxygen and carbon dioxide play a role in cellular respiration

A

Organisms use oxygen to break down food into the chemical energy that powers cell processes. Carbon Dioxide gas is a waste product of cellular respiration and is breathed out by the organsim

Q

What would happen if there was no more oxygen

A

Our brain cells would die off, body systems would shut down, and we would soon die.

Q

How do plants obtain oxygen for cellular respiration

A

Land and aquatic plants have tiny pores in their leaves that absorb oxygen and release carbon dioxide. Land plants get their oxygen from the surrounding air, while aquatic plants absorb dissolved oxygen from the water, they live in. Note that this cellular respiration process is different than photosynthesis. You may recall from a previous lesson that plants take in carbon dioxide and release oxygen through photosynthesis. Plants need both processes to live. In fact, plants can perform the processes of cell respiration and photosynthesis at the same time

Q

Which 2 systems circulatory systems to get cells the materials they need to make energy

A

The respiratory system and digestive system work with the circulatory system to get cells the materials they need to make energy. The circulatory system is the transportation system of the body. It delivers oxygen and nutrients to the body’s cells and carries away waste products, such as carbon dioxide.

Q

Why is water so essential for amphibians

A

Amphibians are born and reproduce in the water, and water keeps their skin moist, which is necessary for breathing

Q

Explain how an amphibian leads a double life

A

Amphibians start out living in water then as adults live on land and depend on lungs and moist skin to breathe

22
Q

How do fish spines work

A

They move side to side

23
Q

How do mammal spines work

A

They move up and down

24
Q

What is the difference between voluntary and involuntary responses to stimuli

A

In a voluntary responses you must think to do your actions while involuntary responses are responses that happen naturally

25
Q

What does your brain do with information from your nerves

A

Your brain uses the information received from your nerves to coordinate all your actions and reactions

26
Q

What is the function of neurons

A

Neurons are nerve cells that send messages back and forth throughout your body via electrical impulses

27
Q

What is the difference between the autonomic and somatic processes of your nervous system

A

Autonomic are with thinking and somatic is thinking

28
Q

Why is your tongue more sensitive to heat than the heel of your foot

A

The tongue has more nerve receptors

29
Q

Nervous System Definition

A

An organ system that receives information from the environment and coordinates a response

30
Q

Stimulus Definition

A

Any change or signal in the environment that can make an organism react in some way

31
Q

Response Definition

A

An action or change in behavior that occurs as a result of a stimulus

32
Q

Neuron Definition

A

A cell that carries information through the nervous system

33
Q

Impulse Definition

A

An electrical message that carries information in the nervous system

34
Q

Sensory Neuron Definition

A

A neuron that picks up stimuli from the internal and external environment and converts each stimulus into a nerve impulse

35
Q

Interneuron Definition

A

A neuron that carries nerve impulses from one neuron to another

36
Q

Motor Neuron Definition

A

A neuron that sends an impulse to a muscle or gland, causing the muscle or gland to react

37
Q

What is the nervous system made up of

A

Brain, spinal cord, and nerves

38
Q

What are the Neurotransmitters

A

They are chemicals that help signals go from neuron to neuron

39
Q

How is the process of spreading information in cells like

A

To send information between cells with gaps the electrical pulse in the cell releases chemicals that carry that impulse to the next cell. These chemicals are Neurotransmitters

40
Q

What are the 2 ways the nervous system work

A

Autonomic and Somatic

41
Q

Autonomic Definition

A

The Autonomic nervous system handles all things that see to happen on their own

42
Q

Somatic Definition

A

The Somatic nervous system controls voluntary actions

43
Q

How does a reflex happen

A

It happens without your brain’s help

44
Q

Which 2 features are found in complex nervous systems of humans and other vertebrates

A

The most complex systems have a nerve cord and a brain

45
Q

Describe the nervous systems of cnidarians

A

A cnidarian’s nervous system is called a nerve net

46
Q

What is a cnidarian’s nervous system made up of

A

It consists of neurons arranged like a net. There are no specialized neurons, so a stimulus to one neuron sends impulses in all directions

47
Q

What is a planarians nerve system like

A

A planarians nervous system includes nerve cords and eye spots

48
Q

Other than vertebrates, which other animal groups have a complex nervous system with a brain and specialized neurons

A

Arthropods and mollusks have nervous systems that include brains

49
Q

How would someone’s memory be affected if they suffered damage to their left cerebral hemisphere

A

This can cause someone to have poor short-term memory, but normal long-term memory

50
Q

Brain Definition

A

An organized group of neurons in the head of an animal with bilateral symmetry

51
Q

Different parts of the brain respond to what

A

Different stimuli
