Science Semester 1 Review Part 2

The food that you eat travels from your mouth, down your esophagus, into your stomach, and through your small and large intestines before your body rids itself of solid waste. As the food passes through your body, it is digested, and you get important nutrients from the food. Which of the following is the correct term used to describe a group of body parts working together to perform a specific function?

• An organism

• A tissue

• An organ system

• An organ

Blood is an odd structure in animals because it is one of the few structures that has functions and is fluid. Blood is mostly made of two types of cells. Red blood cells carry oxygen to all parts of the body. White blood cells protect the body from disease using a variety of methods. Blood is best classified as a/an —

Plant root tips have a layer of cells that function together to grow rapidly to allow the plant to increase the plant’s ability to reach water and stabilize in the ground. Based on this information, what level of organization describes the plant root tips?

• Tissue

• Organ

• Organ system

• Organism

Seeds are the offspring of mature plants. If a seed germinates and survives, it will grow to become a mature plant. Based on this information, what level of organization describes seeds?

• Tissue

• Organ

• Organ system

• Organism

Through which cell structure does waste exit the cell?

• Cell membrane

• Chloroplast

• Vacuole

• Nucleus

Cells remove waste from their cytoplasm by passing it through the cell membrane and out of the cell. What two human body systems perform similar functions?

• Endocrine and excretory

• Excretory and digestive

• Respiratory and endocrine

• Circulatory and skeletal

Many cellular functions can be compared with functions that occur in organisms. Which of the following is not a function that both the cell and the organism share?

• Stores waste material for removal

• Provides structure and support

• Learned behaviors that aide in survival

• Conversion of nutrients into usable energy

As the season turns from fall to winter, what is the most likely response that a wolf’s body has to the changing season?

• The wolf stores more fat to maintain body heat and provide nutrition when there may be less prey.

• The wolf produces less fur and sheds more fur to help the wolf move quickly to find shelter in the cold.

• The wolf produces more melanin causing the fur to be darker so that the pack can see other individuals easily.

• The wolf runs more and eats less food to maintain less body mass to keep warm throughout the winter.
