What are the 5 characteristics of ALL living things?

• grow, respond to stimuli, metabolize, reproduce, moving

• grow, respond to stimuli, breathe, reproduce, made of cells

• grow, respond to stimuli, metabolize, reproduce, made of cells

• thinking, respond to stimuli, metabolize, reproduce, made of cells

Answer explanation

Remember to not be fooled by things that MOST, but not ALL.

ALL- grow, respond to stimuli, metabolize, reproduce, made of cells

MOST- think, eat by mouth, move, breathe- but NOT ALL!!

Which organisms store some of the molecules from food in their bodies to use later as a source of energy and building materials?

• animals but not plants

• both animals and plants

• plants but not animals

• neither animals nor plants

Answer explanation

Remember that this is one of the characteristics of ALL living things- metabolism- changing "food" to energy

Which of the following is food for a plant?

• sugar that a plant makes

• minerals that a plant takes in from the soil

• water that a plant takes in through its roots

• carbon dioxide that a plant takes in through its leaves

Answer explanation

Another one of those 5 characteristics of ALL living things- metabolism- "food" into energy.

Fun FACT: That sugar is the same thing that passes energy to you when you eat salad or an apple.

Using the model, what do carbohydrates, proteins, and fats have in common?

•  Carbohydrates, proteins, and fats all have carbon, hydrogen, and oxygen atoms.

• Carbohydrates, proteins, and fats are all made of the same number and types of atoms.

• Carbohydrates, proteins, and fats all have the same arrangement and types of atoms.

• Carbohydrates, proteins, and fats can all form long chains of molecules.

Answer explanation

All of these have carbon, oxygen, and hydrogen.

Which statement is true about the breakdown of starch?

•  Breaking down starch is not a chemical reaction.

• Animals, but not plants, can break down starch.

• Organisms break down starch into carbon, hydrogen, and oxygen atoms.

• Organisms break down starch into carbohydrate subunits.

Answer explanation

Carbohydrates are sugars. Keep in mind the cracker example and the enzyme amaylase.

• The log uses the mushrooms as a food source.

• The mushrooms use the log as a food source.

• The mushrooms use the log as a source of oxygen.

Answer explanation

What is the best biological explanation for the student being hot and sweaty?

• Her body needed to use more heat energy to run hard.

• Her body needed to burn food more quickly to get energy to run hard.

• Her heart had to pump faster to run hard.

Answer explanation

This is another 5 characteristic of ALL living things- metabolism- "food" to energy and the heat helps us burn the fuel more efficiently.

Which statement is true about photosynthesis?

•  During photosynthesis, plants use carbon dioxide and water in a chemical reaction to create glucose and oxygen.

• During photosynthesis, plants convert thermal energy into chemical energy and stores it as food molecules.

• During photosynthesis, plants convert sunlight into carbon dioxide which the plant then releases.

• During photosynthesis, the plant sweats to release oxygen.

Answer explanation

Carbon Dioxide plus Water (add in a little sunlight) makes sugar and oxygen! This is photosynthesis.
