Potatoes reproduce by growing sprouts on their surfaces as shown.
When planted, these sprouts grow into new plants. This is an example of
pollination.
asexual reproduction.
fertilization.
seed production.
Which of these is the best example of sexual reproduction?
binary fission
budding
fusing gametes
fragmentation
An advantage of asexual reproduction is that it does not require fertilization. What advantage do the offspring of sexual reproduction most likely have as a result of fertilization?
DNA variation may allow survival in a changing environment.
Unfavorable traits from each parent will be eliminated.
Traits will be perfectly adapted to the environment.
DNA will be less varied and therefore more stable.
Some fungi can reproduce either asexually or sexually, resulting in offspring with different characteristics. Sexually produced offspring have
a complex level of cell organization.
a number of organelles in each cell.
a lesser risk of having mutations than asexually produced offspring.
a combination of genetic material from each parent cell.
A main advantage to organisms that reproduce sexually is
being able to conserve energy.
having large numbers of offspring.
greater genetic diversity.
longer life spans.
The gametes of human males and females have the same number of chromosomes. Which best describes what happens to the chromosomes when typical male and female gametes combine to produce offspring?
The chromosomes change shape.
The number of chromosomes doubles.
The chromosomes become larger in size.
The number of chromosomes reduces by half.
A diagram of a plant cell is shown.
What process is shown in the diagram?
meiosis
mitosis
respiration
mutation
Which trait of the salamander pictured below is most likely not inherited?
skin color
body length
missing limb
lack of claws
Which of these cell parts store genetic instructions for the entire organism and transfer those instructions from one generation to the next?
chloroplasts
mitochondria
DNA molecules
nuclear membranes
Which of these is defined as “the passage of genetic instructions from one generation to the next?”
growth
heredity
development
reproduction
Which of these is the best definition of heredity?
the transfer of learning from one generation to the next
the transfer of visible features from one generation to the next
the passage of dominant genes from one generation to the next
the passage of genetic information from one generation to the next
Eye color in human beings is an
instinct.
acquired trait.
inherited trait.
environmentally influenced trait.
Which trait of a pet dog is inherited?
The dog avoids a pet cat.
The dog jumps on a sofa.
The dog rolls over on command.
The dog drools when it smells food.
Which characteristic is least likely to be affected by an individual’s environment?
height
weight
eye color
skin color
Which of these is most likely the cause of a father and son having almost identical-sounding voices?
learned behaviors
environmental conditions
inherited characteristics
instinctive characteristics
The picture shows a kitten, along with its parents. Why does the kitten appear to be different from either parent?
The kitten did not have the proper nutrition during development.
The kitten gets half its traits from both parents, and this creates variety.
The kitten has a disease that makes it look different from its parents.
The kitten is not fully grown and will soon look identical to one of the parents.
Vertebrate animals produce offspring by sexual reproduction. Which is an advantage of this type of reproduction?
Time and energy is used to find a mate in the population.
There is increased genetic diversity within the population.
The offspring grows faster than one that is produced asexually.
The offspring receives its DNA from one parent and is identical to that parent.
Which of the following is a part of the process of sexual reproduction?
budding
regeneration
pollination
fragmentation
Which phrase does not describe asexual reproduction in organisms?
requires two parents
little variation in offspring
only one type of cell involved
duplicates its genetic material
Many invertebrate animals, such as the hydra, reproduce asexually.
What form of reproduction in this stage of the life cycle of the hydra is shown in the diagram?
fission
budding
fragmentation
meiosis
What types of cells are found only in organisms that reproduce sexually?
blood cells
neurons
skin cells
gametes
Why would a scientist use asexual reproduction to grow two offspring of a plant, instead of using sexual reproduction?
The plants would be an exact genetic match.
The plants would have fewer recessive traits.
The plants would have greater genetic diversity.
The plants would be more likely to mutate.
A particular peach tree produces peaches that are more resistant to disease than other peaches. What method would reproduce these exact peaches?
use bees to pollinate the flowers
reproduce by cross-pollination of different peach trees
increase the diversity in the peach tree
ensure that the peach tree reproduces asexually
During which process are nuclei duplicated?
mitosis
respiration
photosynthesis
fertilization
The graphic shows the processes involved in the cell cycle.
The cell cycle is necessary in order for new cells to replace damaged or dead cells. In which part of the cycle are new cells formed?
Growth
DNA Synthesis
Preparation for Division
Mitosis
Which characteristic is the best example of an inherited trait?
eye color
an infection
knowledge of soccer
length of hair
The drawing below shows a breed of cat known as Munchkin.
The short-leg trait would be transmitted to the next generation of cats through
faTS
nutrients
genes
mutations
DNA stores the genetic instructions transferred from one generation to the next. What is DNA?
a molecule
a membrane
a cell nucleus
a spiral-shaped cell
A child’s sex is determined by the sex chromosomes of which person?
grandfather
grandmother
mother
father
Peacocks perform an elaborate dance while displaying their tail feathers. What purpose does this action most likely serve for the peacock?
It keeps their feathers clean.
It enables them to attract a mate.
It allows them to more easily lose their feathers.
It distracts other animals so the peacock can escape.
Which characteristic of a cheetah is more likely to be learned rather than inherited?
speed
a spotted coat
hunting strategies
claws that do not retract
Which process results in offspring that are genetically identical to the parent?
natural selection
mutation
sexual reproduction
asexual reproduction
What is the main function of meiosis in sexually reproducing organisms?
to produce identical cells
to reduce the chromosome number by half
to repair damaged tissues
to increase cell size
Which of the following is an inherited trait in humans?
language spoken
ability to ride a bicycle
eye color
preference for music
