Copper has been used by humans for thousands of years, with evidence of its use dating back to around 9000 BC. It was one of the first metals to be widely used by early humans due to its malleability, conductivity, and corrosion resistance. The exact date of its discovery is not known, as it occurred in prehistoric times.
Concrete examples or specific instances would be used to identify elements at the top of the Ladder of Abstraction, as they are more specific and closer to reality.
Elements like helium, neon, and argon would not work well for electrical wiring purposes as they are gases and do not have the necessary properties to conduct electricity effectively. Elements like gold or silver would be expensive choices compared to copper for this purpose.
Sure, feel free to provide a pun that you would like me to solve using elements from the periodic table.
The run-down area attracted a certain shady element. A new element was discovered at the lab.
Monday 27 April 2009 Is the correct layout. DO NOT use commas. Commas separate elements of a sentence from each other. A date is a collective element. To use the below would be wrong: Say if you use today's date: Monday, 27 April, 2009, or Monday, April 27th, 2009.
Humans can impact abiotic elements, such as air, water, and soil, through pollution from industrial activities, use of chemicals, deforestation, and urbanization. These activities can alter the natural balance of abiotic elements, leading to negative consequences such as climate change, water contamination, and soil degradation. It is essential for humans to adopt sustainable practices to minimize their impact on abiotic elements and preserve the environment.
One hundred percent of all humans use air, without which they would die.
To find out the date
It all depends whether it is a sell by date, use by date, or a best before date. If it is a sell by, then that would be an earlier date than an 'eat by' date so it would probably be OK. If it is a best before, then it probably won't taste as good but will still be safe; if it is after a use by date then it may not be safe so you shouldn't eat it.
There's something wrong with this question. Everything around us is made out of elements. We can't do anything without using a couple of elements. Oxygen might be a good answer. We use some of that from the moment we draw our first breath. But most elements are mixed up, impure. So maybe this is about which was the first "pure", or refined element humans learned to use.
that would mean either humans actually use technology to its potential, or the anti-economy destroyed everything of use and humans are now extinct.
I would call it a symmetrical date.
Yes, acriflavine can expire. It is important to check the expiration date on the packaging and not use the medication if it has passed the expiration date, as effectiveness and safety may be compromised.
A geneticist would use a pedigree to trace the inheritance of traits in humans.
Many documents are similar in their structure. So instead of having to recreate the same components over and over again, you can create or use a template which will have the standard elements, and then you don't have to repeat them. You can then concentrate on the unique parts. So if it was a memo, for example, It would already have the main headings in such as Date or To or From and any boxes or designs drawn, so all you have to do is type in the actual date, who it is to or from and the message. As the structure is from a template, then all memos would look the same. Avoiding having to do the repetitive elements, saves a lot of time and effort.
