A lion stalks a herd of antelope wading in a pond. A flock of water birds on the shore become startled by the sound of the lion’s approach and fly away with a great deal of noise. The birds’ sudden departure gives warning to the antelope, and they are also able to escape safely. What type of relationship exists between the birds and the antelope?
competition
mutualism
commensalism
parasitism

In metaphase of mitosis, chromosomes
form and the nuclear envelope disappears.
are pulled toward opposite ends of the cell.
chromosomes line up along the equator of the cell
chromosomes begin to decondense and the two new nuclei begin to form.
In anaphase of mitosis, chromosomes
form and the nuclear envelope disappears.
are pulled toward opposite ends of the cell.
chromosomes line up along the equator of the cell
chromosomes begin to decondense and the two new nuclei begin to form.

What type of energy conversion occurs in photosynthesis?
Light from the sun to chemical in glucose
Chemical in glucose to chemical in ATP
Which of the following equations represents the overall chemical reaction for photosynthesis?
6O2+ 6H2O → C6H12O6+ 6O2
C6H12O6 + 6H2O→ 6O2+ 6O2
6CO2+ 6H2O→ C6H12O6+ 6O2
6O2 + 6H2O→ C6H12O6 + 6CO2

seedling
xylem
Which type of movement across a cell's plasma membrane requires energy supplied by ATP?
Passive Transport
Simple Diffusion
Active Transport
Osmosis
Which statement describes the process of osmosis in an animal cell?
Sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide.
Water molecules move across the plasma membrane until solute concentrations are equal on both sides of the membrane.
Ions move across the plasma membrane until the inside of the cell has a higher concentration of positive charges.
Enzymes move across the plasma membrane until the cell has completed metabolism.
Which molecule synthesized by plants is a major source of energy for cellular processes in both plants and animals?
Wax
Nucleic Acid
Glucose
Chlorophyll
Active transport, because energy is being used to move molecules against the concentration gradient
Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Osmosis, because energy is not being used to move molecules with the concentration gradient
Endocytosis because energy is not being used to move molecules against the concentration gradient
Energy conversions and synthesis of new molecules
Synthesis of new molecules and homeostasis
Transport of molecules and energy conversions
Homeostasis and transport of molecules
The method in which water moves, for example, water entering a plant cell is...?
Active Transport
Respiration
Osmosis
Facilitated Diffusion
