The role of the calcium ions during an action potential the calcium causes the release of acetylcholine.

Cellular physiology and biochemistry of organisms are influenced by calcium ions (Ca2+). They are essential for neurotransmitter release from neurons, all forms of muscle cell contraction, fertilization, and signal transduction pathways where they function as a second messenger. Many enzymes, including several of the coagulation factors, require calcium ions as a cofactor. In order to maintain the potential difference across excitable cell membranes and to ensure normal bone development, extracellular calcium is also crucial. RDAs for calcium were established by the American Institute of Medicine (IOM) in 1997, and they were revised in 2011.

______ allows computers to divide tasks into parts that can be distributed across each core in a multicore processor.

Answers

Parallel processing allows computers to divide tasks into parts that can be distributed across each core in a multicore processor.

Parallel computing is a type of computation in which many computations or processes are performed simultaneously. Large problems can often be broken down into smaller problems that can be solved simultaneously.

Parallelism is the method of computing two or more processors (CPUs) to process separate parts of the overall task. By distributing different parts of the task across multiple processors, you can reduce the time it takes your program to run. A system with multiple CPUs can perform parallel processing, similar to the multicore processors commonly used in modern computers.

Computer scientists typically use software tools to divide a complex task into multiple parts and assign each part to a processor. Each processor then solves its part and uses software tools to reconstruct the data to read the solution or perform the task.

How does the grain size change from slate to schist? how does the texture of phyllite differ from that of schist? why do you think the micas in these rocks are all parallel?

Answers

Schist is a medium grade sheet-like grain rock, whereas slate is hard and fine-grained rocks with a salty cleft that is caused by the formation of minerals as a result of the metamorphic of the grain ground rocks.

What is slate?Through low-grade regional metamorphism, slate is transformed from an original shale-type sedimentary rock made of clay or volcanic ash into a fine-grained, foliated, homogenous metamorphic rock. It is the foliated metamorphic rock with the finest grain size. Foliation may occur in planes that are not parallel to the direction of metamorphic compression and instead line up with the original sedimentary layers. Slate's foliation is known as "slaty cleavage." Strong compression is what causes fine-grained clay flakes to grow back in planes perpendicular to the compression, which is what causes it. Many slates exhibit a feature called fissility when carefully "cut" by striking parallel to the foliation, with a specialized tool in the quarry. This results in smooth flat sheets of stone that have long been used for roofing, floor tiles, and other purposes.

Because of its extremely tiny grain size and flat grains, phyllite has a particularly sparkly texture. The largest grain size is seen in schist. Schists are made up of scales, whereas phyllite has a foliated texture.

Muscovite and biotite are two minerals that are frequently found in micas and produce the parallel, extremely fine-grained flakes of rock that are seen in igneous rocks with feldspar and quartz. Phyllite, schist, gneiss, and slate are the rocks with the lowest grades, respectively.

Cognitive psychology is an area that focuses on the science of how people think. This branch of psychology explores a wide variety of mental processes, including how people think, use language, attend to information, and perceive their environments.

While it is a relatively young branch of psychology, it has quickly grown to become one of the most popular subfields. Cognitive psychology became more predominant during the period between the 1950s and 1970s.

Prior to this time, behaviorism was the dominant perspective in psychology. Then researchers became more interested in the internal processes that affect behavior instead of just the behavior itself.

This shift is often referred to as the cognitive revolution in psychology. During this time, a great deal of research on topics including memory, attention, and language acquisition began to emerge.

In 1967, the psychologist Ulric Neisser introduced the term cognitive psychology, which he defined as the study of the processes behind the perception, transformation, storage, and recovery of information.
