Many of us take the ability to see colours for 0 GRANTED, unaware that this feature is fairly uncommon. In fact, only a 17 of biological classes can boast better colour vision, mostly birds and butterflies. Whereas animals and insects rely on these for survival, the 18 purpose of advanced colour perception in humans remains unclear.

Some theories suggest that foraging is the reason we as species have such developed eye for colour. Primates, our ancestors, are largely 19 on fruits and berries as source of food would know if it has 20 enough to safely consume. A more exotic idea is that it is related to snakes. Without being able to tell colours apart it is nearly impossible to know whether a snake is 21 , and should therefore be avoided.

However, not everybody is blessed with the perfect 22 to discern colours. One notable instance is Mark Zuckerberg, the founder of Facebook, who allegedly has some problems with perceiving colours. That’s the reason his social network mostly uses shades of blue in its interface, as Mark 23 finds it easier to tell it apart from other colours. Ultimately, it goes to show that nowadays absence of colour vision is more of an 24 rather that a serious condition that affects your quality of life in a dramatic way.

The term ‘brick and mortar’ is used in 0 RELATION to any type of business, usually a shop, that has some degree of physical presence – to speak 17 , an actual place you can come to, rather than just a website. The term owes its origin to the 18 shift towards buying and selling over the Internet in the early 2000, when the online-only approach slowly started gaining traction.

There is a reason that the brick and mortar approach has been losing popularity. Anybody with a semblance of business acumen can see the 19 appeal of shifting towards the online model. Not needing to rent and maintain a place means that the saved funds can help keep the prices at a more 20 level. It also has much higher 21 , as increasing your business will often mean that you have to move to a bigger building. Conversely, your online 22 can be resized quickly and within much lower budgets.

However, most of this criticism can be deemed 23 , as there are plenty of industries where personal touch is more important. This is especially common in businesses with older target audiences, where clientele is less comfortable doing their shopping online. This leads many experts to believe that brick and mortar is likely to make a 24 in the nearest future.

Why do we love spicy things? Go to any restaurant, and you will definitely see at least one person 0________ their food in scorching-hot Tabasco sauce, or eating chilli peppers like bread. That’s because spiciness 17 your body to release endorphins, making you feel a natural high.

Is there such a thing as too spicy? Scoville scale has an answer to that. It measures 18 , or just how hot a pepper is. Specifically, it is an attempt to 19 spiciness – to express it in real numbers, making a great 20 point for people who are into such things. For instance, the habanero pepper is on average 25 times more potent than the jalapeño pepper. The number itself is not abstract too – it is the amount of water required to completely 21 the 22 of heat the pepper gives.

The thing that is responsible for the spiciness is an element called capsaicin. One thing worth knowing is that it is hydrophobic, which means that drinking water is not very effective in alleviating the burning feeling. An 23 drink works much better there, so a glass of orange juice will come in 24 when your mouth is on fire!

We are all familiar with the genre of science fiction – its 0 SETTING is usually the distant future, and space travel is often a big part of it. Now, hard science fiction might sound new. The ‘hard’ part means that this genre focuses on 17 and keeping scientific basis in mind, at times putting it above literary and entertainment values.

However, like any other work of fiction, it still has to retain the fun component. The author does not want the reader to feel 18 by bombarding them with complex terminology or 19 technical descriptions. Instead, the focus shifts to 20 yet exciting world of the future, without straying away from the theoretically possible towards overly 21 . The genre also sets out to educate us – to explain things in a detailed, but also accessible way.

Some might consider this genre niche – that is, it might not be to everybody’s 22 .

So if you have grown 24 with endless stories of time travel and teenagers zooming around in alien space crafts, then the hard fiction genre might be just the thing you were looking for.

Some people do it, whereas others see it as a 0 CRIMINAL offense against food and an assault on common sense. Today we are going to talk about peeling, or removing the 17 layer of a fruit such as an apple.

One might ask – why would people be so divided on such a trivial matter? While the peel might not be to everybody’s taste, they are very rich in 18 elements and antioxidants. The 19 are molecules that prevent or delay oxidisation, a process that damages cells of our body. Finally, a reasonable 20 against peeling is that it takes a lot of time, which could be spent 21 .

However, not every kind of peel is good for you. Orange is one fruit whose peel (also called rind) can be harmful, as it causes undue stress to your 22 tract. Moreover, just like with any other type of peel, 23 pesticides on its surface can be a big risk. That is one of the reasons you should always wash your fruits and vegetables 24 before eating them – it is not the dirt that you should most be afraid of, but the possible traces of chemical treatment.

People today are too busy for many things, even if they are as 0 ESSENTIAL as finding your other half. Before long, an entire industry appeared to address the issue, coming up with a 17 of services aiming at helping you find a partner.

The pioneers of the industry started off as websites, but 18 of smartphones eventually led to a shift towards stand-alone apps. Another common move of online dating platforms in the past was to allow only female members to message first. Many deemed this unfair and so this 19 was soon lifted.

Today, the process of matching is done on the 20 of similar interests, preferences, or geographical proximity. Most dating apps provide an option to pay for additional services, usually to give your profile bigger exposure by suggesting it to more potential matches.

From the very beginning these services had a number of downsides. One of them is how users might take 21 when filling out their profile. For instance, men are more likely to lie about their 22 , whereas women often feel reluctant to 23 their age. Owing to this, finding one’s 24 love online might be trickier than it seems!
