Methanogens can be found in B.human intestines
Roots of plants and synthetic fertilizers can contain oxygen or come into contact with oxygen.
In the given case, no antibiotic is needed for dental procedures.
Based on the updated recommendations from the American Heart Association, there is no need to take a precautionary antibiotic prior to dental proceedings for the majority of people.
It has been suggested by AHA that only those who are at greatest threat of bad consequences from infective endocarditis needs to get the short-term preventive antibiotics prior to routine dental approaches.
It has been recommended by the AHA guidelines that various of the people who have taken preventive antibiotics in the past no longer need them, these include the individuals with the conditions, like mitral valve prolapse, ventricular septal defect, bicuspid valve disease, rheumatic heart disease, and others.
Answer:
Glycosidic Bond
Explanation:
Glycosidic bond is used to form disaccharides. When two monosaccharides joins together, a glycosidic bond is formed resulting in a disaccharide.
I believe it's the first one.
Answer:
a. The operon is under positive control
a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein
b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region
the role of the R protein is
-decrease affinity of Tis / B complex to B region of RB
-bind to the R region on RB
- change the conformation of B region
- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process
Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription
