Group 1 4A 9A

4A Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown.

Which cell that was viewed is most likely a prokaryote?

• Cell W

• Cell X

• Cell Y

• Cell Z

4A A student groups different types of cells as shown. Which table headings should the student use for the two groups?

• #1 Animal Cells

  #2 Plant Cells

• #1 Prokaryotic Cells

  #2 Eukaryotic Cells

• #1 Mobile Cells

  #2 Motile Cells

• #1 Fungal Cells

  #2 Bacterial Cells

4A: A student is studying a prepared slide of a single-celled organism with a microscope. A single-celled organism can be classified as a prokaryote based on the absences of:

• a cell membrane

• ribosomes

• chromosomes

• a nucleus

4A The diagram represents a theory about cells.

Which theory is represented in this diagram?

• The theory that all living organisms are made of cells

• The theory that all living organisms share the same basic genetic components

• The theory that organisms function best when their internal conditions are maintained within narrow limits

• The theory that complex cells evolved after primitive cells engulfed bacterial cells that continued functioning

4A: Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which of these correctly identifies the two cells described in the table?

• Cell 1 is eukaryotic, and Cell 2 is prokaryotic

• Cell 1 is prokaryotic, and Cell 2 is eukaryotic

• Both Cell 1 and Cell 2 are eukaryotic

• Both Cell 1 and Cell 2 are prokaryotic

4A Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water.

Based on the observations of the student, which organisms most likely belong to the taxonomic group for bacteria?

• Organisms 1 and 2

• Organisms 3 and 4

• Organisms 1 and 4

• Organisms 2 and 3

9A A table of four types of carbohydrates is shown.

Which list correctly matches the functions to the types of carbohydrates?

• Energy: glycogen and starch

  Structure: cellulose and chitin

• Energy: cellulose and chitin

  Structure: glycogen and starch

• Energy: chitin and glycogen

  Structure: cellulose and starch

• Energy: cellulose and starch

  Structure: chitin and glycogen

9A: Proteins and carbohydrates have many functions in the body of an organism. Specific proteins and carbohydrates perform specific tasks. Information about a protein and a carbohydrate is given below. How are ferritin and glycogen similar in their primary functions for an organism?

• Both store materials needed by the organism

• Both store energy used by the organism

• Both support the structure of the organism

• Both store information for the organism

9A Students were given a list of seven elements and asked to identify the four elements that are most abundant in biomolecules. Which table correctly identifies the four most-abundant elements in biomolecules?

•

9A An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?

• Carbohydrates and lipids

• Proteins and carbohydrates

• Nucleic acids and carbohydrates

• Lipids and nucleic acids
