The electrons in an atom are arranged in shells that surround the nucleus, with each successive shell being farther from the nucleus. Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals. Electrons in the same subshell have the same energy, while electrons in different shells or subshells have different energies.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

AI won't kill us all — but that doesn't make it trustworthy. Instead of getting distracted by future existential risks, AI ethics researcher Sasha Luccioni thinks we need to focus on the technology's current negative impacts, like emitting carbon, infringing copyrights and spreading biased information. She offers practical solutions to regulate our AI-filled future — so it's inclusive and transparent.

Discover how Anthropic’s Model Context Protocol is transforming AI connectivity and efficiency.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Recommended video: Q&A THE CELL
https://youtu.be/TCqYuFPBfCI
Hello happy friends, are you ready to learn? I’m sarah, and today we’re going to play a q&a game about animals’ vital functions.

Before we start, do you know what animals’ vital functions are? The three vital functions, all animals have to meet so they are able to live?

Of course! They are nutrition, interaction and reproduction.

Now let’s head for the first question:
Do you know what type of diet a bear has? A bear can be an omnivore
herbivore
or carnivore

Exactly! Bears are omnivores! They can eat both plants and meat. Let’s learn a little more about them!

According to their diet, animals can be herbivores...carnivores or omnivores, Herbivores eat plants and herbs, like this giraffe. Within herbivore animals, there are two very special ones, they are ruminants. Ruminants, like goats or cows swallow foods almost without chewing, and they store it, they keep it in their stomachs. Then, when they want to, they return it to their mouths, chew and swallow it again. It seems a bit disgusting, but ruminants are like this.
Carnivore animals only feed On meat and need to hunt to get it. Lions, sharks or eagles are carnivore animals.
Omnivore animals are herbivores on and carnivores at the same time. They eat meat, and vegetables. Bears and hens are omnivores and do you know who else? … people! Human beings are are also omnivores, we can eat chicken, or a salad with its lettuce and tomatoes.

We now know that animals, depending on their diet can be carnivores, herbivores or omnivores. Let’s head to the next question:

What do animals use to interact?
Their nose and mouth
Sound
Or the sense organs.

Of course! To be able to interact, animals use all sense organs, let’s get to know why.

Animals need to get to know the environment, to know what’s happening around them and react before it.
To do this, they use their sense organs.
with their eyes, they can see what’s happening around them, like eagles, who have an excellent eyesight. With their ears, they can hear if an animal with cruel intentions is approaching. With their mouth, they can eat and know if something is good or bad. With their nose, they can detect if there’s tasty food around them and with their skin, thorough touch, they feel tender petting and tickles too!

That’s so interesting! Now we’ve learnt more about interaction function. Let’s head for the last question:

Do you know which of these animals reproduce through eggs, meaning it’s oviparous.

A crocodile,
A bat,
or a mouse

Exactly! Crocodiles reproduce through eggs, like all reptiles. Let’s get to know a little more about animal reproduction.

The reproduction function lets animals create new animals and ensuring future life. Animals have two ways of reproducing. Viviparous animals, are born directly from their mothers wombs. Look, look at how this calf is born from its mother's womb.All mammals like these dolphins or these lions are viviparous. Oviparous animals are born from the eggs their mothers lay. Birds, reptiles, amphibians, fish and almost all invertebrates are oviparous. But there are some animals that can reproduce in other ways. EarthWorms and starfish can reproduce through excision. when a starfish is cut, it divides in two more pieces, each one of them grows and turns into a new starfish. Nature is incredible, don’t you think?

I’m sure you’ve answered all questions correctly, but if you haven’t it’s okay because as I always say, the most important thing is that you’re always wanting to learn and have lots of fun!

Goodbye happy friends! See you next time! Oh and don’t forget to subscribe to happy learning tv.

This organic chemistry video tutorial provides a basic introduction into spin spin splitting / coupling as it relates to proton NMR spectroscopy. It explains how to use the N+1 rule to determine the multiplicity of a H NMR signal. It also discusses the intensity ratio of singlets, doublets, triplets, quartets, quintets, sextets, and septets using pascal's triangle. It also provides an intro into complex splitting by using a triplet of quartets and a quartet of triplets signal as an example which can be simply referred to as a multiplet.
