What is life zone concept?C. Hart Merriam created the term "life zone" in 1889 to refer to regions with comparable plant and animal groups. Depending on height, location, and latitude, the climate and ecology of many places on the planet naturally divide into life zones. Altitudinal zonation is the term for the generally substantial dependence on elevation: the average temperature of an area falls as the height increases.

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.
Answers
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.

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.
Answers
The fetal face is approximately one-third the size of the fetal skull. The mature cranium is around two-thirds the size of the adult skull.
The cranium, the skull's protective outer covering consists of three bones: the frontal bone, two parietal bones, and one occipital bone.
The frontal bone is a single bone on the forehead and rests on top of the eye orbits. It also makes up a significant portion of both sides of the maxilla. The two parietal bones make up the majority of both sides and the top of the skull, as well as a considerable portion of each side of the maxilla. The occipital bone is the most distant cranial bone and the occiput's primary bone. It, like all other cranial bones, is classified as a flat bone, which means that its major role is either protection or providing a large surface for muscle attachment.

Answers
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

Although mouse and human dendritic cells (DCs) are made up of functionally distinct subsets, precise interspecies correlation is currently lacking. In this study, we discovered that murine lung and gut lamina propria CD11b+ DC populations were divided into two subsets: FLT3- and IRF4-dependent CD24+CD64 DCs and contaminating CSF-1R-dependent CD24CD64+ macrophages. CD24+CD11b+ DC loss inhibited CD4+ T cell-mediated interleukin-17 (IL-17) production in the steady state and after Aspergillus fumigatus challenge. Human CD1c+ DCs, which are the equivalent of murine CD24+CD11b+ DCs, expressed IRF4, secreted IL-23, and induced T helper 17 cell responses. Our findings revealed heterogeneity in the mouse CD11b+ DC compartment and identified IRF4-expressing DCs in mucosal tissues that are specialised in instructing IL-17 responses in both mice and humans.

Answers
In cell signaling, the ligand/first messenger or ligand determines the intracellular response. True or false?.
Answers
In cell signaling, the ligand/first messenger or ligand determines the intracellular response this statement is False.
The process through which a cell reacts to things outside of it via signaling molecules that are both inside and on its surface is called cell signaling.
A cell can signal another cell or itself by releasing a chemical messenger called a ligand. The binding has biological effects that can take many different forms, such as affecting gene transcription or translation or modifying cell shape.
Extracellular signaling molecules like hormones or neurotransmitters, which bind to cell-surface receptors and activate intracellular signaling pathways, are the first messengers. These molecules rely on second messengers to spread and amplify the signal within the cell because they are unable to physically cross the cell membrane.
While most pathways share the same basic steps of cell signaling (reception, transduction, response, resetting), there are different pathways.
