Living organisms are development on other living organisms to survive producers make their own food consumers gain energy from producers, and decomposers break down dead matter into essential nutrients that are then released by producers juicers gain energy from the Sun consumers gain energy from the producers and decomposers get energy from dead consumers and recycle it back to the producer all of the above
Answer:
d. induction
Explanation:
A repressor is a protein capable of inhibiting target gene expression by binding to both operator sites and gene silencers. A DNA-binding repressor inhibits the interaction between the RNA polymerase and the DNA promoter sequence, thereby suppressing transcription into RNA. Moreover, the RNA-binding repressor is a protein that binds to the messenger RNA (mRNA) molecule in order to prevent its translation into protein. An inducer can start transcription by interacting with the repressor, thereby separating it from the DNA operator sequence.
Answer:
The science that involves using living organisms to produce needed materials.
Explanation:
I got this question correct!
In exocytosis, a cell expels molecules and other contents that are too large to pass through the cell membrane structure. This discharge is accompanied by the fusion of the vesicular membrane and the plasma membrane. This process is carried out in three ways that separately involve the molecular constituents like endosomes, lysosomes, exosomes, neurotransmitters, etc.
In endocytosis, the body cells ingest various molecules such as proteins, polar molecules, and other substances, through their hydrophobic plasma membrane. This process is carried out by many eukaryotic cells to ingest food particles by surrounding them, and in this case, the plasma membrane is extended outwards. The basic mechanism of both the processes of exocytosis and endocytosis, is more or less the same. Vesicles are the structures used for the transportation of molecules. They are also used for storage and transportation of food. Also, many bacteria and pathogens may enter the body by this process. These structures may have a completely different internal composition as compared to that of the body cells.
Answer:
d) valine; lysine
Explanation:
the conversion of glutamic acid to valine in sickle cell anemia and to lysine in hemoglobin C will change the function of normal protein and that why these disease caused
