Fish give off the compound anomia, which has a pH above 7. To which class of compounds does ammonia belong?

"Antigenic Shift" is a characteristic of the causal agent of the Influenza. It is the result of a major change in the antigenic

gtnhenbr [62]

Answer:

True.

Explanation:

Antigen may be defined as the chemical that has the ability to evoke the and immune response and can harm the living organisms. The specific antibody are produced against the immune response.

The antigens has evolved different mechanisms to prevent themselves from them the immune system of the host. The antigenic shift is the most common change that might occur in viruses that helps the antigen to protect itself by changing its genetic material. No anti viral drugs are available for the viruses.

Thus, the answer is true.

Answer:

Homeostasis is maintained at many levels, not just the level of the whole body as it is ... Of course, body temperature doesn't just swing above its target value

Improved bone regeneration through amniotic membrane loaded with buccal fat pad-derived MSCs as an adjuvant in maxillomandibular

muminat

Mesenchymal stem cells and HAM together may improve bone repair, especially in the horizontal dimension. Additionally, this technology lessens secondary bone resorption and the quantity of collected autogenous bone.

HAM:

Background: Human amniotic membranes (HAMs), a biological membrane with potential for cell therapy, osteogenesis, and healing, have come under the spotlight as a way to improve the results of treating bone abnormalities. The goal of the current study is to clinically evaluate the possibility of HAM loaded with stem cells from the buccal fat pad (BFSCs) as an osteogenic covering for only bone transplants to maxillomandibular bone lesions.
Materials and methods: The current investigation included nine patients with jaw bone abnormalities. Iliac crest bone graft with HAM covering (n = 5) and iliac bone grafts coated with HAM loaded with BFSCs (n = 4) were the two study groups that the patients were divided into. Cone beam computed tomography was carried out for radio morphometric characterization five months after the grafting and before the installation of the implant.
Results: The mean increase in bone width was found to be significantly greater in the HAM + BFSCs group ( $4.42$ ± $1.03$ mm versus $3.07$ ± $0.73$ mm, p < $0.05$ ). Further, the changes in vertical dimension were greater in the HAM + BFSCs group ( $4.66$ ± $1.06$ mm versus $4.14$ ± $1.03$ mm, p > $0.05$ ).

two organisms are in the same phylum but not the same class.another pair of organisms are in the same genus. witch pair has more

Katyanochek1 [597]

Same genus is more closely related. The farther down the list Phylum-Class-Order-Family-Genus-Species you go, the more closely related are the species in that taxon.
