A change in gene location will occur on both chromosomes
Which of the following is essential to proper functioning of all prokaryotic and eukaryotic organisms?
ATP
The element carbon has multiple bonding patterns. Which bonding pattern cannot be formed by carbon?
C≡C≡C
Describe how organisms use DNA and amino acids to synthesize a protein
DNA is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain
Compare eukaryotic cells and prokaryotic cells
Eukaryotic cells contain membrane-bound organelles, and prokaryotic cells do not.
Lungs and capillaries both have porous linings that allow certain substances to move into or out of the structures. Which function do these porous linings most likely serve in living organisms?
Gas exchange
Which process best describes the assembly of proteins from amino acids?
Monomers are linked to form a polymer
Which property of water is most responsible for plants being able to transport water from their roots to their leaves?
The attraction between molecules
Compare carbohydrates and nucleic acids
The bonds in a carbohydrate store energy, and the sequence of nucleotides in a nucleic acid stores genetic information
Which statement best describes a function of the proteins embedded in the plasma membrane of cells?
They selectively allow certain particles into and out of the cell.
Which properties of water are most responsible for the capillary action in plants?
adhesion and cohesion
