    Neuron action potentials: The creation of a brain signal - Khan Academy

    https://www.khanacademy.org/test-prep/mcat/organ-systems/neuron-membrane-potentials/a/neuron-action-potentials-the-creation-of-a-brain-signal

    When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

    A mass spectrometer ionizes atoms and molecules with a high-energy electron beam and then deflects the ions through a magnetic field based on their mass-to-charge ratios ( m / z. ‍. ). The mass spectrum of a sample shows the relative abundances of the ions on the y-axis and their m / z. ‍. ratios on the x-axis. If z = 1.

    Codons. Cells decode mRNAs by reading their nucleotides in groups of three, called codons. Here are some features of codons: Most codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, AUG, marks the beginning of a protein and also encodes the amino acid methionine.

    Yes, square roots can create 2 answers -- the positive (principal) root and the negative root. When you are working with square roots in an expression, you need to know which value you are expected to use. The default is the principal root. We only use the negative root when there is a minus in front of the radical. For example: 8 + sqrt (9) = 11.

    Overview of cell signaling. Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

    Finding slope from graph | Algebra (video) | Khan Academy

    To do that, we take the y value of our first point (our first point is (5, 6) so the y value is 6): 6. And subtract the y value of the other point (the other point is (3,2) so the y value is 2): 6-2=4. So our change in y or rise is 4. Now we can finish by putting the rise over run :D. Rise = 4. Run = 2. Slope = 4/2.

    Here is an example of a double replacement reaction: BaCl 2 ( a q) + Na 2 SO 4 ( a q) → Ba SO 4 ( s) + 2 Na Cl ( a q) In this example, the cations are Ba 2 + and Na + , and the anions are Cl − and SO 4 2 − . If we swap the anions, or cations, we get as our products BaSO 4 and NaCl . Don't forget stoichiometry!

    We know objects can only accelerate if there are forces on the object. Newton's second law tells us exactly how much an object will accelerate for a given net force. a = Σ F m. To be clear, a is the acceleration of the object, Σ F is the net force on the object, and m is the mass of the object.

    Transcription overview. Transcription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble.

DNS Lookup

DNS entries, such as A, NS, MX, and TXT records, are crucial for the functioning of the Internet. The A record maps a domain name to an IPv4 address, while the NS record specifies authoritative name servers for a domain. The MX record identifies the mail server responsible for receiving email messages for a domain. Additionally, the TXT record allows for the association of any text information with a domain name. These records play a vital role in ensuring proper communication and connectivity across the internet.

SEO Analysis

SEO analysis involves examining the performance of a website, including titles, descriptions, keywords, and website speed. It also includes identifying popular keywords and researching competitor websites to understand their strategies. The analysis aims to optimize the website's visibility and improve its ranking on search engines.

Title Tag:
Khan Academy | Free Online Courses, Lessons & Practice

Length: 54 characters

Title tags are usually best kept short, within 50-70 characters. It's important to note that search engines will typically read the entire title tag even if it exceeds 70 characters, but there is a chance they may cut it off or disregard it.

Meta Description:
Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere.

Length: 241 characters

What is the issue about?
TThe description is too long or too short. Search engine crawlers only show the first 150-160 characters of the description in the search results page, so if a description is too long, searchers may not see all of the text. If a description is too short, the search engines may add text found elsewhere on the page. Note that search engines may show a different description from the one you have authored if they feel it may be more relevant to a user's search.

How to fix?
Change the description in the tag in the page source to be between 25 and 160 characters in length.

Meta Keywords:

No meta keywords found.

In the realm of search engine optimization, the meta keywords tag has become a relic of the past due to its potential for misuse, ultimately leading major search engines to disregard it in their ranking algorithms.

A crucial factor in search engine optimization is keyword density, which refers to the proportion of a particular keyword present in the text of a webpage. In order to achieve high rankings on search engine results pages, it is essential to maintain the appropriate keyword density for your primary keyword.

<h3>Trusted content</h3>

In SEO, the primary focus is placed on keywords within the content. The title of the page holds the highest importance, followed by heading tags such as h1, h2, and h3. The h1 heading should be the largest on the page, while the h2 heading should be slightly smaller, and the h3 heading even smaller. This hierarchical structure is crucial for optimizing search engine rankings.

Image Alt Attribute:
55 images found in your page, and 21 images are without "ALT" text.

What is the issue about?
The tag does not have an ALT attribute defined. As a general rule, search engines do not interpret the content of image files. The text provided in the attribute enables the site owner to provide relevant information to the search engine and to the end user. Alt text is helpful to end users if they have images disabled or if the image does not properly load. In addition, the Alt text is utilized by screen readers. Make sure that your Alt text is descriptive and accurately reflects what the image represents and supports the content on the page.

How to fix?
Use the <img alt> attribute to write descriptive content for the image: <img source='pic.gif' alt='Accurate and descriptive keyword text that represents the image.' />.

Website Speed Test (Desktop):
0.01 seconds

Website speed is a measurement of how fast the content on your page loads. Website speed is one of many factors involved in the discipline of search engine optimization (SEO), but it is not the only one. In a recent study, the average load time for a web page was 3.21s.
