Answer:
The carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea is explained below in details.
Explanation:
A mountain stream is a river or stream, normally with a sheer slope, running down a mountainside. Stream velocity is most noted in midstream near the exterior and is crawling along the stream bottom and shores due to friction.
The river stalls down at the entrance, so it doesn't have the energy to carry all the sand, dirt, and clay anymore. These deposits create the flat, regularly triangle-shaped tract of a delta.
Why did the narrator use the phrase “fit together like puzzle pieces” to describe how the cells of a developing human embryo form a human face
A string of amino acids attached together is called a <u>Polypeptide Chain(S)</u>
Answer:
"One gene-one protein" hypothesis states that one gene codes for one protein while the "one gene-one polypeptide" hypothesis states that one gene codes for one polypeptide chain of a protein having more than one type of polypeptide chains.
Explanation:
Beadle and Tatum proposed the one gene-one protein concept to explain the one-to-one correspondence between genes and proteins. Accordingly, one gene carries information to encode one protein. Since enzymes are proteins with catalytic power, a gene encodes the information to produce a single enzyme.
The "one gene-one protein" concept was later modified into the "one gene-one polypeptide" hypothesis. According to the "one gene-one polypeptide" hypothesis, one protein may have more than one polypeptide chain. One gene carries the genetic information to encode one polypeptide. Therefore, a protein with more than one type of polypeptide chains will be encoded by more than one gene.
