following an action potential, a nerve cell goes through a brief refractory period during which it cannot be stimulated. what is true during this refractory period?
following an action potential, a nerve cell goes through a brief refractory period during which it cannot be stimulated. It facilitates the unidirectional flow of the action potential.
Action potential are the electric signal generated by the neurons which occurs to transfer the signal around the body. It occurs by temporary shift in the neuron's membrane potential which is caused due to sudden inflow of the ions.
It is divided into depolarization, repolarization, hyperpolarizatio and refractory period.
In refractory period the nerve cell enters a resting phase and are not able to transfer any action potential.

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.
The size of the fetal face is one-third the size of the fetal cranium while the adult skull is two-thirds the size of the adult cranium.
The face of a fetus is foreshortened and overshadowed by its cranium. Also, his mandible and maxilla are very tiny. On the contrary, the adult cranium is comparatively smaller and his facial bones are comparatively larger than the cranium.
Cranium is the outer protective layer of the skull. It comprises 8 cranial bones and 14 facial bones. It has two main parts: cranial roof and cranial base. The cranial roof consists of frontal, occipital and two parietal bones. The cranial bases also comprises these three types of bones and also includes sphenoid, ethmoid and temporal bones.
The cranial bones are connected by connective tissues during infancy to allow their growth and form one piece. The primary function of cranium includes protecting the brain and providing a link for the attachment of facial muscles.
The size of the fetus ' face increases as it matures and thus has a very small face compared to its cranium. The cranium in the adult is all grown up and does not grow further.

Name the two main organ systems that communicate within the body to maintain homeostasis.
The two important body systems that interact inside the body to ensure homeostasis are the endocrine system and central nervous system .
The principal control systems for ensuring homeostasis are the central nervous and endocrine systems. The endocrine system is made up of glands that generate chemical regulators (hormones). The nervous system senses discrepancies from the brain's normal equilibrium (homeostasis) and sends information to the internal organ in order to compensate. It restores the required balance in a fairly short amount of time. Both systems function mostly instantaneously, however the nervous system could be voluntarily controlled.

Write a paragraph to tell about how this type of rock is formed. Give examples of rocks that are this type and tell what you learned about this rock type.
Igneous rocks form when magma (molten rock) cool and crystallize. This happens either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. Two rocks from identical magma to an igneous rock can become either rhyolite or granite, depending on whether they cool quickly or slowly. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly. If the lava cools almost instantly, the rocks that form are glassy with no individual crystals, like obsidian. Intrusive rocks, also called plutonic rocks, cool slowly without ever reaching the surface. They have large crystals that are usually visible without a microscope.

activation of ampk attenuates neutrophil proinflammatory activity and decreases the severity of acute lung injury
All mammalian cells include AMP-activated protein kinase (AMPK), a fuel-sensing enzyme that is phylogenetically conserved.
Increases in the intracellular AMP-to-ATP ratio trigger the activation of the AMP-activated protein kinase (AMPK), which is a key player in cellular responses to metabolic stress. Although it has been demonstrated that activating AMPK has anti-inflammatory effects, nothing is known about how AMPK may affect neutrophil function and neutrophil-dependent inflammatory events, such as acute lung injury. The study's findings indicate that activating AMPK lessens the severity of neutrophil-driven proinflammatory processes, including acute lung damage, and TLR4-induced neutrophil activation.Learn more about the protein kinase with the help of the given link:

how an organism appears. examples include the presence of flagella, gram stain behavior, and cellular arrangement.
Phenetic or phenotypic classification is how an organism appears, and examples include the presence of cellular arrangement, gram stain behavior, and flagella.
The phenetic, or phenotypic classification, is a primary approach used in biology to divide organisms into categories. The phenetic technique combines species following their observable phenetic characteristics; two species will be classified together if they resemble one another more than either does any other species. Species can be classified according to the cellular arrangement, gram stain behavior, and flagella.
The complete categorization makes up a taxonomic hierarchy of levels where individuals from higher and higher levels of a group appear to be less and less similar to one another. The classification of species phenetically does not require any knowledge of evolution, in contrast to the phylogenetic principle. The species are categorized based only on similarities in observable characteristics, and the same idea can be used to classify any collection of things, alive or inanimate.
