Which answer choice best describes a community?

Praying mantises caring for their yound
Three-spined sticklebacks living in estuaries
Different species of lizards occupying the same niche in a desert
Roosting mother bats recognizing their offspring

Correct Answer

A. Different species of lizards occupying the same niche in a desert

Explanation

The answer choice "different species of lizards occupying the same niche in a desert" best describes a community. A community refers to a group of different species living in the same area and interacting with each other. In this case, the different species of lizards occupy the same niche, which means they have similar roles and requirements in the desert ecosystem. This interaction between different species in a specific habitat is a characteristic of a community.

In what order are the levels in the diagrams?

Population - community - ecosystem
Organism - community - population
Organism - population - community
Ecosystem - population - community

Correct Answer

A. Organism - population - community

Explanation

The correct order of levels in the diagrams is organism, population, and community. This is because an organism is an individual living entity, a population is a group of organisms of the same species living in the same area, and a community is a group of populations of different species living in the same area and interacting with each other. This order represents the hierarchical structure of ecological systems, starting from individual organisms, to populations, and then to communities.

Recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healing time by 25%. Which of these are the most basic levels of organization involved when a bone heals?

Cells and tissue
Cells and organ system
Organ system and organism
Tissue and organ system

Correct Answer

A. Cells and tissue

Explanation

When a bone heals, the most basic levels of organization involved are cells and tissue. Cells play a crucial role in the healing process as they are responsible for the production of new bone tissue. They multiply and differentiate into specific cell types that contribute to the formation of new bone. Tissue, on the other hand, refers to a group of cells that work together to perform a specific function. In the case of bone healing, different types of tissue, such as connective tissue and cartilage, are involved in the repair process. Therefore, cells and tissue are the fundamental levels of organization involved in bone healing.

The table shows some observations made by 4 students during a field trip to a nature area. Which student made observations of a community of organisms?

Correct Answer
student 2, 2

Explanation
Student 2 made observations of a community of organisms because their data entry appears twice in the table. This suggests that they observed multiple organisms within the same community. The repetition of their data indicates that they were focused on documenting the interactions and relationships between different organisms in the nature area.

A science class is planning a field trip to a local farm that has a large pond. Which of the following lists the order of biological organization from smallest to largest that the students can expect to find at the pond?

Organism, community, population, ecosystme
Organism, population, community, ecosystem
Population, organism, community, ecosystem
Population, organism, ecosystem, community

Correct Answer

A. Organism, population, community, ecosystem

Explanation

The correct answer is "organism, population, community, ecosystem." This order of biological organization starts with individual organisms, then moves to populations of the same species, followed by communities of different species interacting with each other, and finally encompasses the entire ecosystem, including both living organisms and their physical environment.

Choose all that apply. Which of the following functions at the same organizational level as the kidney in the human excretory system?

Skeleton
Epithelial tissue
Urinary bladder
Squamous cell

Correct Answer

A. Urinary bladder

Explanation

The urinary bladder functions at the same organizational level as the kidney in the human excretory system because it is involved in the storage and elimination of urine, which is produced by the kidneys. The bladder receives urine from the kidneys through the ureters and stores it until it is expelled from the body through the urethra. Both the kidney and the urinary bladder are important components of the excretory system, working together to remove waste products from the body.

A student is studying the ecology of a playa lake, which forms after a rainfall in a dry lake bed. The table lists the organisms that the student observed. Which level of biological organization has the student described in the table?

Biosphere
Organelle
Ecosystem
Community

Correct Answer

A. Community

Explanation

The student has described a community in the table. A community refers to a group of different organisms living and interacting with one another in a particular area. In this case, the organisms observed in the playa lake after rainfall form a community as they coexist and have relationships with each other in that specific ecological setting.
