The digram are two chromosomes for an organism
What process is associated with the activity of these chromosomes?
binary fission
mitosis
conjugation
sexual reproduction
Analyze the pedigree which shows the inheritance pattern of an autosomal dominant genetic disorder.
If individual R was an affected female, what would be her genotype?
DD
Dd
dd
DD or Dd
A group of students performed crosses between 10 garden pea plants with purple flowers and 10 garden pea plants homozygous for white flowers. They collected 100 healthy seeds of the F1 generation and grew them. They provided equal amounts of water and sunlight to all the plants. During the flowering season, the students observed that all of the plants had purple flowers.
Based on the results of the students’ experiment, what can the students determine is most likely true about the inheritance of flower color in garden peas?
Flower color is determined by a sex-linked gene in garden peas.
Flower color is determined by incomplete dominance in garden peas.
Purple flowers are dominant to white flowers in garden peas.
White flowers are dominant to purple flowers in garden peas.
This image shows the offspring that result from a dihybrid cross between a plant with wrinkled green seeds and a plant with round yellow seeds.
How can this graphic be used to support the idea of independent assortment?
The fact that the seeds can be one of two different colors shows that the chromosomes with the seed color gene must sort independently.
he fact that the seeds can be one of two different textures shows that the chromosomes with the seed texture gene must sort independently.
The idea that alleles sort independently is supported by the fact that some second generation offspring have trait combinations that the first generation parents do not have.
The idea that alleles sort independently is supported by the fact that some second generation offspring have the same trait combinations that the first generation parents have.
A cross is performed between two flowers as shown in the Punnett square.
The R allele codes for red flowers, and the Y allele codes for yellow flowers. If these flowers show an incomplete dominance inheritance pattern, what would be the phenotypic ratio of the offspring of this cross?
1 red : 2 red and yellow stripes : 1 yellow
1 red : 2 orange : 1 yellow
3 red : 1 yellow
1 red : 3 yellow
The diagram shows four different species of birds. Each species has a different beak shape.
Which statement explains how these different beak shapes developed?
natural selection based on diet
selective breeding by humans
resistance to herbicides through continued exposure
inheritance of acquired characteristics
A farmer sprays an insecticide on his tomato plants to kill the insects that are eating the leaves. Some of the insects are resistant to the pesticide.
What process is demonstrated by this example?
abiogenesis
bioaccumulation
biogenesis
evolution
Scientists believe the ancestors of the chimpanzees and the bonobos were once one population that was separated into two groups by the Congo River nearly a million years ago.
What role did this geographic separation have on these two populations of apes?
Over millions of years, the two populations gradually evolved into two separate species of apes.
They adapted to different food sources.
Although previously unable to swim, both populations of apes evolved the ability to cross the river in search of resources.
After the two populations were separated, the amount of genetic variation in both groups greatly decreased.
Antibiotics are prescribed by doctors when people get sick to help them recover from illnesses faster. Improper use of antibiotics has become common and is creating some health problems around the U.S.
Which statement explains the problem with antibiotic overuse?
People with illnesses caused by antibiotic resistant bacteria are now showing up in hospitals.
Antibiotics are habit-forming which leads to serious issues with addiction.
Antibiotics do not work if they are used with other medications.
Record numbers of people are being treated in hospitals for diseases caused by viruses.
A student is constructing a model to illustrate the levels of organization for life on Earth.
Which levels should the student add to the model to show the correct hierarchy?
1: Biome; 2: Population; 3: Ecosystem
1: Biome; 2: Ecosystem; 3: Population
1: Ecosystem; 2: Biome; 3: Population
1: Population; 2: Biome; 3: Ecosystem
If the decomposers were removed from the food web, which process for maintaining balance in an ecosystem would be altered first?
maintenance of atmospheric quality
maintenance of the hydrologic cycle
generation of soils
recycling of nutrients
Which explanation best describes the importance of the carbon cycle?
It supplies the amino acids which are the building blocks of proteins.
It is essential in the production and metabolism of sugars for energy.
It is necessary for the formation of phosphates which form DNA and RNA.
It is used in forming water which is necessary for organisms.
The biomass of organisms from 4 different trophic levels is shown in the data tables. Which table shows the aquarium that would be stable?
Animals that do not have the ability to make vocalizations have evolved other ways of communicating within a species. One unique method is the use of pheromones, a chemical that is given off as a signal.
Which example represents the use of pheromones for communication?
when ants signal each other about a new food source
when dolphins signal each other about a school of fish
when prairie dogs signal the arrival of a predator
when a mother wolf signals to her lost pup
1.
Which example best illustrates organisms' dependence on abiotic factors?
Cheetahs hunt antelope in the savannah.
Tree ferns compete for sunlight in the forest.
Monkeys feed off bananas in the jungle.
Bats pollinate cactus flowers in the desert.
This graph shows how the population of bison in a section of present-day Yellowstone National Park has changed over time since 1860
What is the approximate carrying capacity for bison in this section of the park?
150
275
350
400
The diagram shows four stages of primary succession in no particular order.
Which sequence shows the stages in the correct order?
1, 2, 3, 4
2, 1, 4, 3
3, 1, 4, 2
4, 2, 1, 3
The Shearon Harris nuclear power plant, which is located 20 miles southwest of Raleigh, NC, provides efficient, inexpensive energy. What is a negative impact of the power plant?I
It reduces dependence on fossil fuels.
It decreases use of coal-fired power stations.
It produces radioactive wastes.
It increases local biodiversity.
