Answer and Explanation:
The entire length of longissimus muscle extends from the mastoid process of the temporal bone to the sacrum. The sacrum consists of 4 or 5 vertebrae that are fused for strength to transmit weight of a stationary animal to the rest of the body. Sacrus has a large base and short neutral spine for attachment of back muscles.
 
        
             
        
        
        
Proteins of DNA Replication. DNA Helicases - These proteins bind to the double stranded DNA and stimulate the separation of the two strands. DNA single-stranded binding proteins - These proteins bind to the DNA as a tetramer and stabilize the single-stranded structure that is generated by the action of the helicases
        
             
        
        
        
The three types of carrier-mediated transport are present facilitated diffusion, primary active transport, and secondary active transport which involve integral membrane proteins. Three characteristics are present in all kinds of carrier-mediated transport: saturation, stereospecificity, and competition.
The saturation is defined as the saturability of the carrier proteins which only have a finite number of solute binding sites. 
Many binding sites be accessible at lower solute concentration concentrations, and as the concentration rises, so does the rate of transport. However, the number of accessible binding sites decreases and the rate of transport plateaus at high solute concentrations. Finally, saturation is attained at a point known as that of the transport maximum, or Tm, at which all of the binding are occupied.

Answer:
element
Explanation:
An element cannot be broken down by any chemical means. However, nuclear reactions can lead to the generation of new elements.
