In what ways does DNA differ from RNA, and what are three key distinctions between the two molecules?
DNA and RNA are both nucleic acids, but they have key differences. One major distinction is that DNA is double-stranded, while RNA is single-stranded. Another difference is that DNA contains the sugar deoxyribose, while RNA contains ribose. Additionally, DNA uses the base thymine, while RNA uses uracil instead.

What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
The stability of the three-dimensional shape of many large molecules is dependent on?
The stability of the three-dimensional shape of many large molecules is dependent on interactions such as hydrogen bonding, disulfide bridges, hydrophobic interactions, and electrostatic forces between different regions of the molecule. These interactions help maintain the specific shape and structure required for the molecule to function properly. Any disruption to these interactions can lead to loss of stability and functional changes in the molecule.
3 elements common to all organic molecules?
All organic molecules are comprised of covalent bonds between hydrogen atoms and carbon atoms. There are many other elements that play a role in modifying the structure of organic molecules, such as oxygen, phosphorous, and nitrogen.
How many molecules does ozone have?
Ozone has three oxygen atoms. Ozone has two forms: O-O=O and O=O-O, and it oscillates between these forms.
How do ADP and ATP differ in the number of phosphate molecules?
ADP have two phosphate molecules and ATP have three phosphate molecules in it.
Is lime stone an igneous rock?
No, a limestone is a sedimentary rock. There are three types of rocks: sedimentary, metamorphic and igneous. That's the simple answer for the complex distinctions between the types of rocks.
What molecules is are lost when a triglyceride is formed?
Three molecules of water are lost when a triglyceride is formed. Each water molecule is released during the condensation reaction between a glycerol molecule and three fatty acid molecules to form a triglyceride.
Why third order reaction usually not is not possible?
Third order reactions imply reaction between three molecules, which implies collision between three molecules. From a probability standpoint this is much less likely than, say, a second-order reaction, where only two molecules must come together.
How do the three types of levers differ from one another?
The three types of levers differ based on the position of the load, effort, and fulcrum. In a first-class lever, the fulcrum is between the load and the effort. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.
Which relatively weak type of bond help stabilize did three dimensional structure of large molecules?
Hydrogen bonds help stabilize the three-dimensional structure of large molecules by forming between polar molecules, such as water, and within molecules, such as in protein and DNA structures. These interactions are important for maintaining the structure and function of biological molecules.
What are the three parts of a bond?
The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions. The three parts of a bond is atoms, molecules, and ions.
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
What is the difference between balsa wood and pinewood?
They differ by both density and stiffness. Balsa is about/almost three times lighter and pine is three times stiffer. N.J.
Why the properties of water are different i its three states of matter?
The properties of water differ in its three states of matter (solid, liquid, gas) because of the arrangement of water molecules and the intermolecular forces between them. In the solid state (ice), molecules are closely packed in a rigid lattice structure, resulting in a fixed shape. In the liquid state, the molecules are more loosely packed, allowing water to flow and take the shape of its container. In the gas state, water molecules have high kinetic energy and are far apart, leading to the ability of water vapor to expand to fill any available space.
What are the three assumptions of the kintic theory?
The three assumptions of the kinetic theory of gases are: 1) Gas molecules are in constant, random motion; 2) Gas molecules are negligible in size compared to the distance between them; and 3) Gas molecules do not exert attractive or repulsive forces on each other except when they collide.
