Vacuole perform digestion in amoeba while stomach perform digestion in mouse.
Explanation:
Amoeba is a unicellular organism so they lack stomach. The food which is taken are digested in the vacuole of the amoeba with the help of specific enzymes and absorbed by the cytoplasm in order to use for performing different activities, while mouse is a multicellular organism and have the stomach which perform the function of digestion. The digestive system of mouse is similar to humans.
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
Answer:
Proteins are like carbohydrates and fats (lipids) because they contain carbon, hydrogen and oxygen. On the other hand, proteins also contain _nitrogen__________ while carbohydrates and fats do not.
Explanation:
Proteins are formed by units: amino acids. These are organic molecules that contain carboxyl (COOH) and amino (NH2) groups. These groups bind to the carbon called alpha (α), which also binds to a side chain (R chain) and a hydrogen atom (H). There are 20 types of amino acids.
Answer:
Neither evolution is not real.
Explanation:
God created everything on earth in space and everything beyond what we can see feel or hear.
