Characteristics of Life
What characteristic of life involves unicellular and multicellular organisms?
Define negative feedback.
What is a response to stimuli that reverses the condition back towards homeostasis?
Is a rock living? List a characteristic of life it does/doesn't follow.
What is no? What is that it doesn't have cells, can't reproduce, doesn't have DNA, doesn't grow or develop, doesn't metabolize, doesn't respond to stimuli, doesn't maintain homeostasis, and doesn't adapt?
Humans eating food is an example of this characteristic of life
What is metabolism?
Define bioligy.
What is the study of life?
Does adaptation happen immediately? Define it.
What is no, adaptation is change over a long period of time.
Define positive feedback.
What is a response to stimuli that enhances the condition away from homeostasis?
Is a tree living? List a characteristic of life that it does/doesn't follow.
What is yes? What is it's made of cells, it can reproduce, it has DNA, it can grow and develop, it metabolizes, it responds to stimuli, maintains homeostasis, and adapts?
An earthworm turning away from a bright light is an example of what characteristic of life?
What is the response to stimuli?
What is the smallest unit of life?
What are cells?
What is teh sum of all chemical reactions occuring in na organism at any given time?
Which type of feedback loop is childbirth an example of?
What is positive feedback?
Is a frog living? List a characteristic of life that it does/doesn't follow.
What is yes? What is it's made of cells, it can reproduce, it has DNA, it can grow and develop, it metabolizes, it responds to stimuli, maintains homeostasis, and adapts?
Your child having brown hair and blue eyes, just like you, would be an example of which characteristic of life?
What is based on genetic code (has DNA)?
Define DNA.
What is the genetic code that you inherit from your parents, found in every cell?
Difference between growth and development.
What is growth is when something gets bigger, and development is a physical change in appearance over time?
What feedback loop is used when your temperature gets too high or too low?
What is negative feedback?
Is a sun living? List a characteristic of life that it does/doesn't follow.
What is no? What is that it lacks cells, doesn't grow or develop, doesn't reproduce, and doesn't metabolize?
A caterpillar forming a cocoon and becoming a butterfly would be an example of what characteristic of life?
What is developments?
What are all living things made up of?
What are cells?
Name all 8 characteristics of life.
What is organized and made of cells, reproduces, has a genetic code, grows and develops, has metabolism, responds to stimuli, maintains homeostasis, and changes over time?
Describe what is happening with the picture on the board.
What is when body temperature rises above normal, the nervous system signals the blood vessels to dilate and the sweat glands to secrete. The body heat is lost to its surroundings, and the temperature drops toward normal.
What is when body temperature drops below normal, the nervous system signals the blood vessels to contract and for the body to begin to shiver. The contraction conserves the heat, and the shivering generates it. The temperature rises to normal.
Is a virus living? List a characteristic of life that it does/doesn't follow.
What is no? What is that it isn't made of cells, it can't grow, it can't maintain homeostasis, and it can't metabolize?
A 12 year old getting 3 inches taller over the summer would be an example of which characteristic of life?
What is growth?
What is the difference between asexual and sexual reproduction?
What is asexual reproduction requires only one parent and is a genetic clone, whereas sexual reproduction requires two and there is genetic variation.
