Which of the following is an example that includes evidence of a chemical change?
A sample of zinc is placed in water and it settles to the bottom.
A solid block of ice is heated, and it completely melts into a liquid.
Sugar that is burned gives off an odor and turns brown and then black.
A sample of a mineral is broken down into smaller pieces.
A physical change can be distinguished from a chemical change because this happens in a physical change:
The properties of the substance may change, but no new substances are produced.
The properties of the substance change for only a short time but will return to their original state.
An entirely new substance with new properties forms as a result of the change.
A new substance is produced, but the new substance has properties identical to the original substance.
The image shows what happens when cold medicine tablets are placed in room-temperature water. What evidence would indicate that a chemical change has occurred?
The tablets dissolve in water.
The water becomes cloudy.
The water level increases slightly.
Bubbles are given off.
Four mixtures are made by combining two clear liquids, and observations are made. Which mixture demonstrates that a chemical change has occurred?
Mixture 1: The combined liquids have a greater mass than either of the starting liquids.
Mixture 2: The liquids, when mixed, produce a white solid, which settles to the bottom.
Mixture 3: The mixture of the two liquids takes the shape of the container.
Mixture 4: The denser of the two liquids lies below the other, less dense liquid.
Evidence of a chemical change can be observed when–
a solid melts into a liquid.
cookies are crumbled.
a drink is poured from a can to a cup.
a banana turns brown after being cut.
A wilted plant returns to an upright position after being watered. This is an example of the effects of which of the following forces?
Geotropism
Gravity
Turgor pressure
Thermal gradient
Geotropism explains which of the following phenomena?
Water collects in rock crevices, freezes and expands, and shatters the rock.
A seed is planted upside-down, but the roots still grow in the direction of gravity.
Two tectonic plates move toward each other, collide, and form a mountain.
After a natural disaster, all animal life disappears from the affected area.
Sunflowers have specialized cells that enable the sunflower to track the Sun. Which of the following allows the sunflower to move to face the Sun?
Gravity
Electricity
Friction
Turgor
A potted plant is tipped onto its side. As the roots continue to grow, in which direction, shown in the illustration, will they grow?
A
B
C
D
The roots of plants grown on the space shuttle while in orbit around Earth all have different orientations. A logical conclusion is that the irregular root growth is caused by the lack of -
soil.
glucose.
gravity.
sunlight.
Sieve-tube cells and companion cells work together to transport sugar and nutrients inside plants. Together, sieve tube cells and companion cells form -
a tissue.
an organ.
an organ system.
an organism.
The smallest units of life in plants are -
tissues.
cells.
organs.
organ systems.
The roots of a plant help to anchor the plant to the soil, and are also used for food storage and water extraction. Roots are made up of tissues, such as xylem, phloem, and pith. In which level of organization would the roots of a plant most likely be classified?
Cell
Organ system
Tissue
Organ
Water moves inside plants using xylem, a structure made up of a collection of cells that form the tube-like xylem. Xylem is classified as -
a tissue.
an organ.
an organ system.
an organism.
When a plant performs photosynthesis, the radiant energy of the Sun is –
released into the atmosphere.
used up in the process.
transported into the soil through the roots.
stored as chemical energy.
Which of the following organisms regularly transforms radiant energy into chemical energy?
Deer
Tree
Cow
Human
Which of the following organisms transforms radiant energy into chemical energy?
Butterfly
Grass
Mouse
Deer
The energy cows need to move about comes from the grass they eat. The energy in the grass is transformed from-
For any activity such as running, jumping, or hunting, animals have to use energy obtained from food. What organelle performs a similar function within a cell to fuel cellular activities?
Nucleus
Mitochondria
Vacuole
Cell membrane
What function in plant cells is comparable to an animal eating food?
Chloroplasts absorbing solar energy for cellular activities
Nuclei directing cellular activity from information held in DNA
Vacuoles storing waste, protecting the rest of the cell from contamination
Cell walls providing rigidity and support for the cell structure
The New Mexico whiptail lizard can reproduce both sexually and asexually. The most reliable way to determine that a group of offspring of New Mexico whiptail lizards was produced through asexual reproduction would be to look at which of the following characteristics?
Physical appearance
Habitat location
Behavior patterns
Genetic variation
The offspring of an organism produced through asexual reproduction is always–
genetically identical to its parent.
created by vegetative propagation.
made of cells with a cell wall.
different from its siblings.
If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is -
identical to only one parent.
identical to all of its siblings.
a unique combination of traits.
the recessive traits from each parent.
Provided is a table of organisms and some data on their characteristics. Based on the information in the table, which organism is likely to produce offspring with the greatest genetic diversity?
Black mold
Bell tree dahlia
Spruce
Hydra
All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism -
makes its own food.
is unicellular.
lives in a marine habitat.
reproduces asexually.
