Which of the following levels of organization would accurately fill the gap in the diagram above?

Molecules -> Organelles -> ___________ -> Tissues

• organ

• organism

• organ system

• cell

Which sequence represents the levels of biological organization from smallest to largest?

• organism -cell - tissue - organelle- organ system- organ

• organelle- cell- tissue- organ- organ system- organism

• organ system- organ- organism- cell- tissue- organelle

• organelle-organ system- cell- organism- tissue- organ

Which of the following biological molecules is correctly paired with one of the functions it primarily serves in living cells? 

• enzymes-are biological catalyst that speed up chemical reactions
• carbohydrates - component of cytoskeleton 
• lipids - catalyze chemical reactions 
• proteins - long term energy storage

Which best describes how enzymes function in the body?

• Enzymes are converted into products by the reactions they catalyze.
• One enzyme can catalyze many different reactions. 
• An enzyme is used once and then destroyed by the cell.
• Enzymes lower the activation energy of reactions.

Why can DNA be transferred between different organisms?

• because they are all identical

• because they share the same genetic code

• because they are abiotic factors

• because they live in the same area

The genetic code is found in the DNA of an organism. Which statement about the genetic code is correct?

• all organisms have the same sequence of DNA nucleotides

• the genetic code is found only in eukaryotic cells because they have a nucleus

• the components that make up genetic code are common to all organisms

• all organisms change their genetic code before passing it to their offspring

What is the relationship between a protein, the cell, and DNA?

• DNA is produced by protein which is produced in the cell

A section of a nucleic acid is shown above. The process represented in the diagram produces a molecule that is complementary to the template strand of DNA. What type of molecule is produced?

• New DNA

• Polypeptide

• Messenger RNA

• Carbohydrate

Part of an important cellular processing involving DNA strand is modeled above. What is the purpose of this cellular process?

• Preserving genetic information for future generations

• Deleting the information in the sequence produced from the DNA template

• Transcribing information in the DNA sequence for use by the cell

• Producing more nucleotides for the DNA sequence
