is a mathematical modeling approach to predicting the outcome of natural selection on behaviors when multiple organisms are interacting.
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
selection, directional selection and disruptive selection.

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.

after suffering a head injury, derick exhibits weak and uncoordinated movement of the jaw as well as numbness of the tongue and lower gums. which nerve was likely damaged?
Answers
Derick likely damaged the Trigeminal nerve after suffering a head injury since his symptoms are weak and uncoordinated movement of the jaw and numbness of the tongue and lower gums.
The trigeminal nerve is a part of the nervous system primarily responsible for sensing pain, touch and temperature in the face and sends the signal to the brain. The trigeminal nerve is the fifth of 12 cranial nerves and called the cranial nerve V.
There are two trigeminal nerves, one on each side of your body. They originate in the brain and travel throughout the head. The trigeminal nerve has three branches that perform various functions:
• Ophthalmic – related to forehead, eye and upper eyelids sends nerve impulses from the upper part of the face and scalp to the brain.
• Maxillary – which refers to the upper jaw extends to the lower eyelids, nose, cheeks and upper lip and gums is responsible for sensations in the middle part of the face.
• Mandibular – or the lower jaw branch aids sensation to the lower part of the face, like the jaws, lower lip and gum. These nerves also have a motor function and help in biting, chewing and swallowing.

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.

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.

What is Preproinsulin?Preproinsulin is used to start the manufacture of insulin in pancreatic beta cells. Prevalence glucose levels, which fluctuate pre- and post-prandially, have a significant dynamic effect on preproinsulin production. The endoplasmic reticulum (ER) translocation apparatus components linked to successful orientation of the signal peptide, translocation, and signal peptide cleavage of preproinsulin — all of which are required to start the pathway of proper proinsulin folding — accompany upregulated translation of the insulin precursor. It is remarkable that the efficiency of folding (or "foldability") of proinsulin has been retained due to evolutionary constraints on its basic structure, which are separate from those preserving the biological function of insulin.

The presence of ribosomes, which synthesize proteins, connected to the RER's outer surface distinguishes the two morphologically.In general, the endoplasmic reticulum's job is to make proteins so that the remainder of the cell can operate.
