which of the following best describes the information of the bond shown in figure 1? (FORMATION OF A PEPTIDE BOND)
a covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O
which statement is the most accurate description of the reaction in figure 1? (FIGURE 1. POLYPEPTIDE REACTION) (POLYPEPTIDES ARE CONTINUALLY BEING FORMED AND DEGRADED ONE OF THESE PROCESSES IS SHOWN)
it represents a polypeptide chain that is broken down though a hydrolysis reaction
which of the following best predicts how the amino acid deflation will affect the structure of the CFTR protein
it will affect the primary secondary and tertiary structure of the CFTR protein
which of the following best depicts the tertiary structure of the two proteins in water ? the diagrams in the options are not drawn to the same scale as those in figure 1 and figure 2
it's the ones that are hidden away
The sequences for two short fragments of DNA are shown above. Which of the following is one way in which these two segments would differ?
(C) Segment 1 would become denatured at a lower temperature than would segment 2 because A-T base pairs have two hydrogen bonds whereas G-C base pairs have three
which of the following best describes the structures of carbohydrates
they occur as monomers, chain of monomers and branched structures
the synthesis of protein or carbohydrate polymers always produces which of the following as a byoproduct
water
based on the molecular structures shown in the figure which molecule is likely to be solid at room temperature
Palmatic acid because the absence of carbon-carbon double bones allow the molecules to pack closely together

Nucleid acid #1 contains adenine-thymine base pairs, whereas nucleic acid #2 does not.
a student anazlyzed a viral genome and found that the genome had the following nucleotide composition • 28% adenine • 20% thymine • 35% cytosine • 17% guanine
Single- stranded DNA
which of the following statements is correct ? (OXYGEN- BINDING CAPABILITY OF MYOGLOBIN AND HEMOGLOBIN)
at 40 mm Hg partial pressure myoglobin has a greater affinity for oxygen then hemoglobin has.

carbon atoms covalently bonded to each other
based on figure 1. which of the following best describes how the properties of water at an air-water interface enable an insect to walk on the waters surface
hydrogen bonds between the molecules at the surface of the water provide surface tension which allows the water surface to deform but not break under the insect
which of the following is responsible for the cohesive property of water
hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule
which of the following is most directly responsible for waters unique properties
it forms hydrogen bonds
this group of questions refers to the following groups of biological compounds A. proteins B. carbohydrates C. nucleic acids D. lipids E. steroids
nucleic acids
which of the following statements best describes how organisms such as rabbits obtain the carbon necessary for building biological molecules
rabbits eat plants and break down plant molecules to obtain carbon and other atoms that they rearrange into new carbon- containing molecules
which of the following statements best describes how molecules released by the fish become nutrients for the plants?
the ammonia molecules released by the fish are converted by the bacteria to nitrates which are used by the plants to make proteins and nucleic acods.
which of the following best describes a structural difference between DNA and RNA?
the backbone of DNA contains deoxyribose, where as the backbone of RNA contains ribose.
which of the folowing graphs is the most apropiate representation of the experimental results documented in the table?
the bar graph
which of the following statements about glucose, galactose and fructose is most likely true ?
the carbohydrates have different properties because they have different arrangements of barbón, hydrogen, and oxygen atoms

which of the following characteristics of figure 1 best shows that the fragment is RNA and not DNA
the identity of each nitrogenous base
which of the following best describes how amino acids affect the tertiary structure of a protein
the interactions of the different R groups with other R groups and with their environment determine the tertiary structure of protein
which statement best helps explain the formation of the hydrogen bond represented in the figure ?
the nitrogen has a partial negative charge and the hydrogen starched to the oxygen has a partial positive charge
