Example Question #5 : Describe Unique Organisms' Life Cycles And Similarities
In the photo below, something unique is taking place. A caterpillar will build a cocoon and stay inside for seven to ten days. While inside it is called a(n) _______. When it emerges, it is a butterfly!
Nymph
Pupa
Tadpole
Egg
Pupa
The caterpillar forms itself into a pupa or chrysalis, and it remains inside as it transforms into a butterfly. The pupa stage may last a few weeks to several months, depending on the species. The case around the pupa hardens to protect the caterpillar as it grows into the butterfly.
Example Question #41 : 3rd Grade Science
What is a life cycle? Example: During a frog's life cycle, it changes shape and form.
A type of bicycle that has one wheel instead of two.
The circle that animals travel in when they migrate.
The cycle that water travels from the ground to the atmosphere.
The series of changes in the life of an organism.
The series of changes in the life of an organism.
The life cycle of plant or animal (humans included) is the series of changes that the organism undergoes in its life. It starts at reproduction and moves through the different stages of life until it ends and begins over with the offspring. Different animals have different life cycles, and they are not all the same.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
What is a trait? Example: A unique trait of the giraffe is its long neck.
A measure of intelligence
A quality or characteristic of something
A like or dislike of a plant or animal
Swapping goods in order to get something
A quality or characteristic of something
A trait is a quality or characteristic that can be used to describe something. In the example provided, a unique trait of the giraffe is its long neck. This characteristic is specific to a giraffe and can be used to describe its appearance. Often the word trait is also heard in English Language Arts when describing a character trait from a story or text.
Example Question #2 : Explain Variations Of Traits In Groups Of Organisms
Why are there differences in siblings if they have the same parents?
It is entirely random, and no one knows what any child might look like.
Different genes and traits are inherited from the parents.
Oldest siblings always get the same traits as their mothers.
Most siblings look and act the same; there are few differences.
Different genes and traits are inherited from the parents.
When siblings are born, they have different genetic make-ups and inherit different traits from their parents. One child might be born with red hair like the mother and another with brown hair like their father. They may both be tall like their father and have the same shaped eyes like their mother. There will be similarities between the offspring, but no two will be exactly alike because of the differences in the genes they inherit.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
The gorillas in the picture look very similar, but there is a difference in their hair color.
Why would the baby gorilla look slightly different than one of its parents?
The baby is a mix of the traits and characteristics of both parents.
The adult gorilla is in the sun, and the baby is in the shade, so they look different.
This is not the gorilla's baby; it is just watching it for a friend.
Gorillas never look like their mothers. They only look like their fathers.
The baby is a mix of the traits and characteristics of both parents.
The baby gorilla looks different and has darker hair than the parent because it is a mix of both parents' genes and traits. The mother may have more brown/red hair while the father has very dark hair to the baby takes more after the father. Every child born is a mix of their two parents, some genes and traits from each will be instilled in the baby. As plants and animals grow older, they also change in appearance and may start to look like one parent more than the other.
Example Question #1 : Inheritance Of Traits
There are variations of inherited traits that exist in groups of similar organisms because they have different inherited information.
True
False
True
The statement presented is accurate and true. There are variations or differences in the traits of animals, even within the same groups and families. Each offspring inherits different information from their parents, so there are slight differences between them all.
Example Question #5 : Explain Variations Of Traits In Groups Of Organisms
Plants and animals do not have traits inherited from their parents.
True
False
False
This statement is false and untrue. Plants and animals inherit their traits and genes from their parents. Each offspring is a mix of both parents and will display characteristics from their mother and father. No two plants or animals are precisely the same because they each have unique traits.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
Why does the puppy in the photo below look so similar to both of its parents?
The puppy does not look similar to the adult dogs.
The puppy is a clone of the adult dogs.
The parent's traits have been passed to the puppy.
The adult dogs are not the puppy's parents; they are siblings.
The parent's traits have been passed to the puppy.
Plants and animals inherit their traits and genes from their parents. Each offspring is a mix of both parents and will display characteristics from their mother and father. The adult dogs are all the same species, color, patterns, and breed, so they will pass on traits that will cause the puppy to look similar.
Example Question #41 : 3rd Grade Science
Why does the kitten in the photo below look different from its mother?
Kittens never look like their mother, only their father.
That cat is not its mother.
It is a mix of both the mother and father's traits.
The kitten is dirty, and you cannot tell its colors.
It is a mix of both the mother and father's traits.
The kitten looks different from the parent because it is a mix of both parents' genes and traits. The mother has orange, white, and brown fur while the kitten only has orange and white. It is possible the father was more orange than other colors, and these genes were the strongest. Every child born is a mix of their two parents, some genes and traits from each will be instilled in the baby. As plants and animals grow older, they also change in appearance and may start to look like one parent more than the other.
Example Question #1 : Explain Variations Of Traits In Groups Of Organisms
DJ and Johar are brothers, but they don't look alike! How can they be brothers but have variations in their appearance?
Youngest siblings always get the same traits as their mothers.
Children inherit about 75% of their genes from their mother and 25% from their fathers, so they have a mix of traits.
Male siblings always look like their father.
Each child inherits different genes from their parents, in a 50:50 ratio, so they have a mix of traits.
Each child inherits different genes from their parents, in a 50:50 ratio, so they have a mix of traits.
When siblings are born, they have different genetic make-ups and inherit different traits from their parents. One child might be born with red hair like the mother and another with brown hair like their father. They may both be tall like their father and have the same shaped eyes like their mother. There will be similarities between the offspring, but no two will be exactly alike because of the differences in the genes they inherit.
