In simple summary form, the calvin cycle requires an input of __________ for every product that is formed and the output product is __________, which is used for glucose synthesis.
In simple summary form, the Calvin cycle requires an input of 3CO2 for every product that is formed and the output product is a three-carbon molecule which is used for glucose synthesis.
The Calvin cycle refers to the three essential processes of photosynthesis that are light-independent. Although the Calvin Cycle is not explicitly dependent on light, it is dependent on light indirectly because the required energy carriers (ATP and NADPH) are results of light-dependent processes.
Light-independent reactions are begun during fixation, the initial stage of the Calvin cycle; CO2 is fixed from an inorganic to an organic molecule.
In the second step, ATP and NADPH are utilized to convert 3-PGA to G3P, which is subsequently transformed to ADP and NADP+. Three molecules of CO2 enter the cycle for every six molecules of G3P generated. As an output, one G3P exits the cycle. The remaining five are kept and rearranged to make RuBP. Furthermore, the three-carbon molecule glyceraldehyde-3-phosphate (G3P) is removed from the cycle for glucose production.
RuBP is replenished near the end of the Calvin Cycle, allowing the system to prepare for further CO2 fixation.

is a mathematical modeling approach to predicting the outcome of natural selection on behaviors when multiple organisms are interacting.
Evolutionary game theory is a mathematical modeling approach to predicting the outcome of natural selection on behaviours when multiple organisms are interacting.
What is natural selection?According to modern concept of evolution natural selection is not a bloody battle as was emphasized by Darwin and Wallace.
It is a peaceful process that has little to do with, "struggle for existence" or "elimination of unfit" or "survival of the fittest".
Natural selection really means differential reproduction ( some members of the population produce lage no of offspring, some are few and still others none.
Those that produce large no of offspring contribute greater percentage of genes to the gene pool of the next generation than those that produce fewer offspring.
If differential reproduction continues for many generation ,then genes of the individual which produce more offspring will become predominant in the gene pool of the population.
This leads to change in the gene frequency of the population.
Individual which are best adopted to the environment having greater no of surviving ones.
Survival of the organism to the reproductive age and their selection for mating is the important factors which results in differential reproduction.
There are three types of natural selection stabilizing
selection, directional selection and disruptive selection.

Answer:
Explanation:

Answer:
Galapagos species are among those populations whose members do not interbreed. The reasons that keep them from mating is that they are separated due to differences in songs and beaks, individuals only recognize and respond to songs of their own species. Therefore, geographic isolation and different environments led to changes in traits that affected mating.

regulatory small rnas circumvent the conventional quorum sensing pathway in pandemic vibrio cholerae
Bacteria communicate with molecules of extracellular signaling known as autoinducers through a process called quorum sensing (QS) (AIs). Bacteria are able to coordinate gene expression on a population-wide scale in response to AIs, mimicking multicellular animals in certain ways. A phosphorelay circuit that interferes with the production of numerous short regulatory RNAs is used internally by Vibrio cholera EI Tor, the causative agent of the current cholera pandemic, to transduce AI information (sRNAs). The mRNA encodes the principal transcriptional regulator HapR and these RNAs form a base pair and inhibit translation of each other.HapR regulates the expression of virulence factors and the development of biofilms in V. cholera. Here, we uncover a QS mechanism that is sRNA-dependent but HapR-independent. In this system, the sRNAs base-pair with a new target mRNA to activate translation by avoiding the creation of a stem-loop structure, which inhibits translation. We demonstrate that the conventional V. cholera strain, which purportedly lacks QS due to a non-functioning HapR and produced prior pandemics, nevertheless demonstrates QS-controlled gene expression via this novel HapR-independent mechanism.

Flaviviruses are a bunch of enveloped positive-stranded RNA viruses accountable for notable mortality and morbidity throughout the world. Flaviviruses fuse with the endosomal membranes of the prey cell in a pH-dependent fashion by entering cells via a clathrin-dependent endocytic pathway. Flaviviruses derived from the endoplasmic reticulum assemble at bud into membranes as immature virions on which E and prM proteins interact as heterotrimeric spikes.
The flaviviruses maturation process is staged by the proteolytic cleavage of the precursor membrane protein into shifting to infectious particles from the inert virus. The peptide β-barrel structure consists of the fusion loop in E, controlling fusion with host cell membranes. during maturation, The structure helps to identify the stages of the pH-directed conformational metamorphosis and leads to the release of pr when budding from the host.
