based on the molecular structures shown in the figure, which molecule is likely to be solid at room temperature?

Palmitic acid, because the absence of carbon-carbon double bonds allows the molecules to pack closely together.

which of the following statements best describes how organisms how organisims 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 best describes a structural difference between DNA and RNA?

The backbone of DNA contains deoxyribose, where as RNA contains ribose.

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 depicts the tertiary structures of the two proteins in water? The diagrams in the options are not drawn to the same scale as those in Figure 1 and in Figure 2

A2

which statements best helps explain the formation of the hydrogen bond represented in the figure?

The nitrogen has a partial negative charge, and the hydrogen attached to the oxygen has a partial positive charge.

which statements is the most accurate description of the reaction shown in Figure !?

it represents a polypeptide chain that is broken down though a hydrolysis reaction.

which of the following correctly illustrates a dipeptide and an amino acid in the optimal position to form a tripeptide?

A1

based on the result of the experiment, which of the following types of molecules did the bacteriophages most likely inject into the bacteria cells?

DNA

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 carbon, hydrogen, and oxygen atoms.

The synthesis of protein or carbohydrates polymers always produces which of the following as a byproduct?

Water

Which of the following statements is true?

at 40 mm Hg partial pressure, myoglobin has a greater affinity for oxygen than hemoglobin has.

based on the 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 molecules at the surface of the water provide surface tension, which allows the water surface to deform but not break under the insect.

why do hydrogen bonds form between water molecules?

hydrogen bonds form between water molecules because a positive charge and a negative charge is attracted to each other

which of the following statements best describes how molecules realeased 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 acids.

which of the following is an accurate description of the process shown in figure 1

the formation of a covalent peptide bond in a dehydration synthesis reaction

which of the following best describes how amino acids affect the tertiary structure of a protein?

the interactions of the different R-groups and with their environment determine the tertiary structure of the protein.

Explain how ice floating on the surface of a body of water affects the water in a way that is benefecial to the organisms in it.

the surface of ice floating affects the water beneficially by bassically the ice on the surface makes the water below warmer in which organisms can survive

explain why the arrangement of water molecules is different in ice and water

they are different because when the molecules freeze they form this kinda of latter kind a shape into each other making them not move as time goes by because basically they are froze

which of the following best describes the structures of carbohydrates?

they occur as monomers, chains of monomers, and branched structures
