A fossilized cell is discovered, and evidence suggests it reproduced on its own and had free-floating DNA with no nucleus. Which type of organism would this most likely be?

• prokaryote

• eukaryote

• plant cell

• animal cell

The hypothesis that the evolution of a species occurs in periods of rapid

    change separated by periods of little change.

• Speciation

• Fitness

• Gradualism

• Punctuated Equilibrium

A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to

• maintain homeostasis

• detect variations

• attract mates

• obtain nutrients

What is the process called by which organ systems maintain a relatively constant internal environment, or a healthy equilibrium between all body systems?

• Osmosis

• Homeostasis

• Stimulus

• Antibody-antigen binding complex

Provides a barrier against injury and infection; helps regulate body temperature; protects against dehydration; makes you sweat and induces gases. All of this to help you maintain homeostasis.

• Circulatory System

• Digestive System

• Endocrine System

• Excretory System

• Integumentary System

A human & a Tape Worm: The tape worm gets a place to live in the intestines of the human and food from the human. The human loses weight and nutrients from the tape worm.

• Mutualism
• Commensalism
• Parasitism

What type of symbiosis?  Hummingbirds feed on nectar from flowers.  The flowers are pollinated by hummingbirds as they move from flower to flower.

• commensalism
• mutualism
• parasitism
• predation

In the cell pictured, which way would water move?

• Into the cell, causing the cell to swell

• Out of the cell, causing the cell to shrink

• In and out of the cell equally, keeping the shape the same

In the cell pictured, where would water move? 

• Into the cell, causing it to swell

• Out of the cell, causing it to shrink

• In and out of the cell equally, causing the shape to stay the same

Leafy celery stalks were placed into coloured water in a beaker overnight. The following day, the students observed the color of the celery leaves changed from green to red. The students cut across the edge of the celery and observed the small tube openings are also red.

How do the plant systems work together to make the movement of the liquid possible?

• The roots absorb the water and dissolved minerals and then move up the stem

• The roots anchor the plant into the soil and the stem holds the leaves up.

• The roots absorb carbon dioxide and move up the stem.

• The roots and the stem lose water vapor to the soil.
