What is a resource?
A resource is anything that people use?
100
What are the names of the plant parts that contain the reproductive cells?
The pistil contains the egg cells, and the stamen contains the sperm cells in plants.
100
What is a gene?
A gene is the part of the chromosome that carries the information that controls a trait.
100
What results from mutations?
Mutations create new and different traits in species.
100
What subject did Mendel use to describe and analyze the results of his experiments?
Mendel needed mathematics.
200
What is a renewable resource?
A resource that can be replaced within a reasonable amount of time
200
What occurs during the first step of the reproduction of a many-celled organism?
The first step is two parents contributing reproductive cells to form the offspring cell.
200
How many genes does a multi-celled organism inherit for each trait?
At least two
200
What could occur in the reproduction of an mutated organism?
The mutated trait could be passed down to the offspring.
200
Why did Thomas Hunt Morgan work with fruit flies?
Morgan discovered that certain cells in fruit flies have giant chromosomes.
300
What happens to the parent cell during reproduction of a single-celled organism?
When a single-celled organism divides and splits to produce offspring, the parent cell ceases to exist.
300
How does the offspring compare to either of its parents of many-celled organism?
Offspring are never identical to each other or either of its parents.
300
What are three examples of traits that are easy to see and affect how a person looks?
Color, shape, and sizes of body structure.
300
What are three examples of selective breeding?
Plumper turkeys, short-legged sheep, and larger ears of corn.
300
On what observation did Mendel base his conclusions during pea plant reproduction?
Mendel was observing the traits of the offspring pea plants.
400
How can chromosomes be described?
Chromosomes are threadlike structures in the nucleus of a cell.
400
What did an offspring of a multi-celled organism receive from its parents during reproduction?
Offspring receive cells from their parent that contain the genetic information found on the chromosomes.
400
Why are some traits not easy to see?
Traits may include diseases that are on the inside of the body.
400
How can mutations be helpful to a species?
Having a greater variety of traits can help a species survive changes in its environment.
400
During the time of Mendel's work, what scientific discovery had not yet occurred?
Chromosomes had not yet been discovered because microscopes were not strong enough.
500
How can the chromosomes be described in the offspring cells of single-celled reproduction?
The chromosomes in the two offspring cells will look exactly like each other. They will also be identical to the parent cell before it divided.
500
How would the process of growth of a many-celled organism be described?
Growth occurs during the division of cells, in which the cells split but remain attached.
500
What is the possible outcomes of offspring in the reproduction of two hybrid organisms?
The offspring could have only dominant genes, have only recessive genes, or be hybrid.
500
What is the name and process of growing seedless fruit?
Grafting occurs when a branch of a seedless fruit is attached to the trunk of a normal plant.
500
How can Mendel's fame be described?
The conclusions Mendel drew about how traits are inherited still hold up today.
