Example Question #1 : Patterns In Behavior Of Parents And Offspring
Why would this bear show its babies how to climb a tree?
To have fun with them
To keep them safe
To get away from the babies
To keep them safe
This behavior that the bear is showing is a way to stay safe and find food. Bears are great climbers, but they have to learn! Mother bears will show the babies how to climb, what foods are in threes to eat, and show that when they are in danger, they can climb the tree to safety.
Example Question #2 : Patterns In Behavior Of Parents And Offspring
Monkeys using tools is a survival behavior.
True
False
True
This is a true statement. Monkeys make tools to scare away snakes or predators, to play with, and to find food. Monkeys can push a stick into an anthill and then eat the ants off of it. They also will wave the sticks at a snake or hit them with it to scare them away from the group.
Example Question #1 : Determine How Parents And Offspring Behave To Survive
Bear 1: Makes a safe, warm cave home, stores food for winter, feeds her cubs, and keeps them safe in winter.
Bear 2: Sleeps in a tree, has no food for winter, and cubs have nowhere warm to sleep.
Which bear is helping its cubs to survive?
Both bears
Bear 1
Bear 2
Bear 1
Bear 1 is helping her cubs to survive. She has prepared for the winter and for having her cubs. She has a warm place to sleep, food, and is prepared to keep her cubs healthy and safe. Bear 2 is not behaving in a way that will keep the cubs safe.
Example Question #2 : Determine How Parents And Offspring Behave To Survive
Which animal is behaving in a way that will help it to survive?
The swan and her babies are behaving in a way to help them survive. The mother is carrying the small babies on her back to keep them safe and close. The babies can watch her search for food so they can learn the skill. The other animals are sleeping or playing.
Example Question #51 : Life Science
For up to the first three years of a baby elephant's life, they depend on their mothers to feed them. Around age two, the baby calf starts to eat on its own but still needs its mother's milk. The other female elephants in the herd - it's older cousins and aunts - will protect the calf, help the mother find food, and watch the baby. The mother elephants show them how to find food and what is best to eat. Once the babies become mothers, they will teach their babies the same lessons.
What pattern of behavior can be learned in this passage about elephants?
Female elephants show the baby something one time, and then the babies have to do it.
Female elephants protect, feed, and teach the baby elephants.
Baby elephants can live without their mothers very young.
Female elephants protect, feed, and teach the baby elephants.
Female elephants in a heard protect and teach the baby elephants how to survive. They rely on their mothers not only for milk but also important lessons that they will show their offspring one day.
Example Question #52 : Life Science
Elephants use tools to help them survive. They will scratch their backs with tree branches and use their trunks to pick things up and move them. Mother elephants will hold the tools and use them for their babies to see so they can learn too. The mother elephants will show the babies how to use their trunks for bathing, blowing bubbles, and making noises.
What is a pattern in the mother elephant's behavior?
They make the babies learn on their own.
They teach the babies skills to survive.
They hide from the babies behind trees.
They teach the babies skills to survive.
The mother elephants in this text exhibit the same pattern of behavior; they teach the babies skills to survive. The mother elephants teach them to use tools and how to use their trunks. This is a pattern seen more than once in the text.
Example Question #13 : Patterns In Behavior Of Parents And Offspring
What is a pattern?
Something that happens only once.
Something that repeats again and again.
The way you pet a dog.
Something that repeats again and again.
A pattern is something that repeats over and over. Patterns can be seen in math, science, nature, and everyday life! If something is repetitive it can be a pattern.
Example Question #53 : Life Science
Elephants are very smart and can communicate with each other. They will touch each other and use smell to send messages. Elephants also use their trunks to trumpet or make sounds to speak to each other. They will make different noises based on what is happening. They can alert to danger, show love, excitement, fear, or anger. The mother elephants show the babies how to communicate and allow them to practice.
What pattern of behavior do the elephants show?
Elephants only communicate with babies.
Elephants communicate with each other.
Elephants do not have patterns in their behavior.
Elephants communicate with each other.
This text shows a pattern of behavior among elephants; they communicate with each other! The mothers teach babies how to use their trunks to make sounds depending on what they are trying to "say." Elephants have their own "language" to communicate with, and the babies learn from adults.
Example Question #54 : Life Science
Mother elephants will show love and discipline their babies. If a baby elephant does something they shouldn’t, the mother will slap the baby with her trunk. She will correct the baby if it is making a mistake. Mother elephants are also very loving and will help babies get up if they fall, carry them when they are too tired to walk, and have fun swimming together.
What does this passage tell readers about the behavior of mother elephants towards their offspring?
They don't let the babies know if they made a mistake.
They are mean all the time.
They are strict but loving.
They are strict but loving.
The mother elephants described in this text are loving with their offspring. Not only will they help the babies, but they will also have fun with them, and discipline them if needed, so they learn the right way to act. They behave much like human mothers and have similar patterns in behavior. They can be tough on the babies, but they are only trying to help them survive.
Example Question #55 : Life Science
Baby birds will chirp and cry to let their parents know they are hungry and want food. Baby humans will cry when they want their bottle. Puppies whine and will nudge their mothers to get milk.
What pattern of behavior are these babies showing to help them survive?
Crying to get food
Yelling because they're mad
Making noise to have fun
Crying to get food
All of these offspring are crying out for their parents to feed them. They are using their only means of communication to get their parent's attention to bring them food or provide them with milk. This is a pattern that is learned over time. When they cry the food comes, they will repeat this behavior because it works.
