True/False... If false correct the answer.
True
At a doctor's appointment, a one month old baby weighs 8 lbs and is 18 inches long. That baby was 7 lbs and 17 inches long at birth. This is an example of ...
Growth and Development
What is the word for made of one cell only? AND What is the word for made of many cells?
Unicellular and multicellular
Why do all living things need energy?
To carry out life functions/survive.
Characteristics of living things are passed on to the next generation through...
DNA
Living things must be multicellular.
True/False... If false correct the answer.
False- Living organisms can be unicellular or multicellular.
Your body shivers when you are cold and sweats when you're hot. This is because of the concept of...
Maintaining homeostasis.
What is the difference between biotic and abiotic?
Biotic is living things/factors and Abiotic is nonliving things/factors.
Imagine a plant in a room with a bright light source on one side. How would the plant react over time? Which characteristic is this?
The plant would likely grow toward the light source.- Respond to environment.
When living things react and are sensitive to their surroundings, this is
responding to stimuli
Because fire grows, gets and uses energy and responds to its environment, it is considered a living thing/biotic.
True/False... If false correct the answer.
False, fire is not living because it is not made of cells and does not contain DNA.
The night before a big game or a marathon, athletes often like to eat a big dinner, why?
They need to get energy so they can use it during their event.
What is the other "name" for genetic code?
DNA
Adaptations are features that help organisms survive in their environment. Can you think of an example of an adaptation that helps an organism thrive in a harsh environment?
Answers will vary.
Living things either make their own food, eat other things or break it down because,
They need to get and use energy.
Nonliving things can share SOME qualities of living things.
True
Your pupils dilating (getting bigger to let more light in) in the dark and constricting (getting smaller to limit the amount of light) in the sun would be an example of which characteristic of life?
Responding to the environment/stimuli
What are the two types of reproduction AND what's the difference?
Asexual Reproduction= 1 parent
Sexual Reproduction = 2 parents
Plants and humans both are considered living. What is the major difference between how they get and use energy?
Plants make it on their own. Humans need to eat/get energy from an outside source.
When a body is stable inside regardless of outside conditions, this is
internal balance- homeostasis
Growth and development in living organisms always involve an increase in size.
False, Growth can also involve changes in form or structure, as in the case of metamorphosis in insects.
Many desert animals have changed over time (when compared to their ancestors) to have lighter-colored fur to reflect sunlight and avoid absorbing heat.
Evolve/adapt over time
What is the difference between growing/developing AND evolving/adapting?
Growth and development happens in an organism's life cycle. Evolving and adaptation is a change over a long period of time that happens to a species as a whole.
How do we define life in terms of science/characteristics?
Answer will vary.
