1.Proteins are linear polymers built of monomer units called amino acids. The construction of a vast array of macromolecules from a limited number of monomer building blocks is a recurring theme in biochemistry. Does protein function depend on the linear sequence of amino acids? The function of a protein is directly dependent on its threedimensional structure.<span>Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer. Thus, </span>proteins are the embodiment of the transition from the one-dimensional world of sequences to the three-dimensional world of molecules capable of diverse activities<span>.
</span>2.Proteins contain a wide range of functional groups<span>. These functional groups include alcohols, thiols, thioethers, carboxylic acids, carboxamides, and a variety of basic groups. When combined in various sequences, this array of functional groups accounts for the broad spectrum of protein function. For instance, the chemical reactivity associated with these groups is essential to the function of </span>enzymes,<span> the proteins that catalyze specific chemical reactions in biological systems</span><span>

Answer:
1. Physical models: smaller and simpler representations of the thing being studied. Eg. A globe or a map is a physical model of a portion or all of Earth.
2. Conceptual models: ties together many ideas to explain a phenomenon or event.
3. Mathematical models: sets of equations that take into account many factors to represent a phenomenon. Mathematical models are often done on computers.
4. Mental models: personal and internal representations of external reality that people use to interact with the world around them. They are constructed by individuals based on their unique life experiences, perceptions, and understandings of the world.
Answer:
At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. ... The temperature may warm or cool. After the front passes, the sky is usually clearer and the air is drier.

Recombinant DNA or rDNA is the general term given to the process of taking a piece of a DNA and merging it with another strand of DNA. The combination of two or more different strands of DNA allows scientists to be able to produce a new and different strand of DNA. Combination of the DNAs of two different organisms is one of themost common recombinant process. The combination of these strands of DNA will give way to the creation of the cure of a lot of genetic diseases in the future like cell anemia, cystic fibrosis and the likes.
