Structure & Function Of Living Things
- 1.
A group of tissues that work together to perform a task is called a(n) (7.12C)
- A.
Body
- B.
Cell
- C.
Organ
- D.
Organism
Correct Answer
C. OrganExplanation
An organ is a group of tissues that work together to perform a specific task. Tissues are made up of cells, and organs are made up of different types of tissues. Each organ has a specific function within the body, such as the heart pumping blood or the lungs exchanging oxygen and carbon dioxide. Therefore, an organ is the correct answer to describe a group of tissues working together.Rate this question:

Which of the following is a good example of the close relationship between structure and function in an organism (7.12A)
- A.
The male Northern Cardinal is bright red to be more visible to predators
- B.
A cow's stomach has four separate chambers to digest the nutritionally poor food they eat
- C.
Bobcats have large, sharp fangs for drinking water
- D.
The holow bones of birds make them easier for predators to eat
Correct Answer
B. A cow's stomach has four separate chambers to digest the nutritionally poor food they eatExplanation
The structure of a cow's stomach having four separate chambers is directly related to its function of digesting nutritionally poor food. The four chambers allow for a more efficient digestion process, as the food can be broken down and processed in stages. This close relationship between structure and function is evident in the specific adaptation of the cow's stomach to its dietary needs.Rate this question:

Botanists use leaves to identify plants. Which trait of the leaves shown would be most useful in identifying the plants they came from? (7.11A)
- A.
Color of leaf
- B.
Function of the leaf
- C.
Presence or absence of veins
- D.
Arrangement of leaves on a stem
Correct Answer
D. Arrangement of leaves on a stemExplanation
Botanists use the arrangement of leaves on a stem to identify plants. This trait refers to how the leaves are positioned on the stem, such as whether they are opposite or alternate. The arrangement of leaves can vary greatly between different plant species and can be a key characteristic in distinguishing one plant from another. Therefore, the arrangement of leaves on a stem would be the most useful trait in identifying the plants they came from.Rate this question:

Which of the following is true about structure and function? (7.12A)
- A.
It is only observed in organisms
- B.
It is not observed in cells, tissues, or organs.
- C.
It is only observed in organelles
- D.
It is observed at all levels of organization
Correct Answer
D. It is observed at all levels of organizationExplanation
Structure and function are observed at all levels of organization. This means that the relationship between the structure (the way something is built or organized) and the function (the purpose or role it serves) can be seen in organisms, cells, tissues, organs, and even organelles. This concept is a fundamental principle in biology, as the structure of a biological component determines its function and vice versa.Rate this question:

Some kinds of fish live most of their lives in salt water but lay their eggs in fresh water. Their ability to survive in different environments is an example of -(7.12A)
- A.
Adaptation
- B.
Camouflage
- C.
Habit
- D.
Hibernation
Correct Answer
A. AdaptationExplanation
The ability of some fish to live in salt water but lay their eggs in fresh water is an example of adaptation. Adaptation refers to the process by which an organism adjusts to its environment in order to survive and reproduce. In this case, these fish have evolved the ability to tolerate different levels of salinity in order to utilize both salt and fresh water habitats for different stages of their life cycle. This adaptation allows them to take advantage of different resources and increase their chances of survival and reproduction.Rate this question:

From the data given in this table, which characteristics could help classify seashells belonging to the Tellin Family? (7.2E) Type of Shell Size Color Hinge Type Location Water Temp Bodega tellin up to 6 cm creamy white weak coast warm Salmon tellin 1 cm pink weak coast warm Speckled tellin 7-10 cm yellow & white weak coast warm
- A.
Color, size, and hinge type
- B.
Size, hinge type, and location
- C.
Color,, size, and water temperature
- D.
Hinge type, location, and water temperature
Correct Answer
D. Hinge type, location, and water temperatureExplanation
The characteristics that could help classify seashells belonging to the Tellin Family are hinge type, location, and water temperature.Rate this question:

What do some organisms do which enables that species to survive winter? (7.11B)
- A.
Pant
- B.
Migrate
- C.
Estivate
- D.
Shed their coats
Correct Answer
B. MigrateExplanation
Some organisms migrate during winter in order to survive. Migration is the process of moving from one place to another, often in search of more favorable conditions. By migrating to warmer regions during winter, organisms are able to escape the harsh conditions and lack of resources that come with the season. This allows them to find food, shelter, and suitable temperatures for survival.Rate this question:

Which of the following is not an adaptation allowing the organism to survive in its environment? (7.12A)
- A.
Desert kangaroo rat never drinks water but only gets liquid from the food it eats.
- B.
A crocodile regrows teeth when its teeth are lost from eating.
- C.
Snakes can go a month between meals
- D.
A brother & sister with different color hair.
Correct Answer
D. A brother & sister with different color hair.Explanation
The adaptation mentioned in the other options directly relate to the survival of the organism in its environment. The desert kangaroo rat's ability to obtain liquid from its food, the crocodile's ability to regrow teeth for continued eating, and the snake's ability to go a month without food all help them survive in their respective environments. However, the different hair color of a brother and sister is not an adaptation that aids in survival.Rate this question:

1What part of the daffodil helps the plant to store food to survive winter? (7.11B)
- A.
Bulb
- B.
Flower
- C.
Stem
- D.
Leaf
Correct Answer
A. BulbExplanation
The bulb of a daffodil helps the plant to store food to survive winter. During the growing season, the leaves of the daffodil capture sunlight and convert it into energy through photosynthesis. This energy is stored in the bulb as starch, which serves as a source of food for the plant during the dormant winter period. The bulb contains layers of fleshy scales that store nutrients and energy, allowing the daffodil to survive until spring when it can resume growth and produce flowers.Rate this question:
