Answer:
D
Explanation:
Stem cells transplanted into the facial tissue of two people with Parkinson’s disease led to sustained reductions in motor and non-motor symptoms, lower medication doses, and a better quality of life, a case study reported.
Answer:
The correct answer is - 1:1:1:1.
Explanation:
Mendel performed cross in between peas with round, green seeds (RRyy) with peas having wrinkled, yellow seeds (rrYY)
gametes : Ry and rY
↓
F1 : RrYy
Test cross is the cross between f1 offspring and recessive parent which is
gametes : RY, Ry, rY, ry and ry
↓
F2 : RrYy, Rryy, rrYy, and rryy.
So, the phenotypic ratio of the offspring would be - 1:1:1:1.
Answer:
The microorganism–microorganism or microorganism–host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype selection. In addition, the establishment in the environment depends on the species diversity, since high functional redundancy in the microbial community increases the competitive ability of the community, decreasing the possibility of an invader to establish in this environment. Therefore, these associations are the result of a co-evolution process that leads to the adaptation and specialization, allowing the occupation of different niches, by reducing biotic and abiotic stress or exchanging growth factors and signaling. Microbial interactions occur by the transference of molecular and genetic information, and many mechanisms can be involved in this exchange, such as secondary metabolites, siderophores, quorum sensing system, biofilm formation, and cellular transduction signaling, among others. The ultimate unit of interaction is the gene expression of each organism in response to an environmental (biotic or abiotic) stimulus, which is responsible for the production of molecules involved in these interactions. Therefore, in the present review, we focused on some molecular mechanisms involved in the microbial interaction, not only in microbial–host interaction, which has been exploited by other reviews, but also in the molecular strategy used by different microorganisms in the environment that can modulate the establishment and structuration of the microbial community.

Explanation:
Systemic circuit is defined as one of the two circuit of circulation that occurs in human body.
<h3><u>Explanation</u>:</h3>
The circulatory system is divided into two phases in the human body. They are:
A. Pulmonary circulation
B. Systemic circulation.
The pulmonary circulation is the short circuit of circulation that starts from the right ventricle, goes to lungs via pulmonary artery and returns to left auricle via pulmonary vein.
The systemic circulation is the bigger circuit that starts from the left ventricle, goes to each and every organ of the body via aorta, and returns to the right auricle via venacava.
