Answer:
Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. While named rare earths, they are in fact not that rare and are relatively abundant in the Earth's crust.
Explanation:
PLS MARK BRAINLIST IF THIS HELPS!!!
the answer is because many of the concepts and ideas in theories are not directly observable.
For example, one of the most important theories that try to explain the formation of the universe is the Big Bang theory.
But, since this theory stated that the event happened million years ago, we couldn't make a possible effort to observe it and prove it's accuracy.

Answer:
The oldest and major source to Taoism is Tao Te Ching (also spelled Dao De Jing), which translates to The Book on the Way and Virtue. It was written by the legendary Lao Tzu (Lao Zi) somewhere between the 7th and the 4th century BC in China. The old classic still has a lot to teach us.
Tao Te Ching consists of 81 chapters about the Way: its mystery, its cosmology, and what it teaches us about how to conduct our lives the wisest.
On this Tao Themes website, the 81 chapters are sorted according to their themes, which is not the case in the Tao Te Ching, where they appear in an order that seems at least partly to be due to chance - or maybe the writer's impulse, while composing the book. It's also possible that the original book is a collection of proverbs from different sources, done long ago by someone else than their author or authors.
I hope that by sorting the chapters into Tao Themes categories, it will be easier for the reader to examine Lao Tzu's thoughts on different subjects. The Tao Te Ching chapters often return to certain topics, making similar or just slightly altered statements about them. When the Tao Te Ching chapters are sorted according to themes, it's possible to see the patterns of Lao Tzu's thoughts more clearly and to explore them at depth.
Also, this Tao Themes division gives you a chance to focus on certain aspects of Taoism, without having to go through the whole book.
Answer:
Stranger wariness
Explanation:
Once one baby has developed a secure attachment with his/her caregiver. The phenomenon of stranger wariness starts to appear.
Stranger wariness refers to the anxiety that babies experience when they are approached by an unfamiliar person, specially when they are under novel situations. Since babies prefer familiar adults, they might react with concern, fussing or crying when approached by an stranger.
In this example, Tyra's niece gets a smile from the mail carrier and she hides her face in Tyra's shoulder and looks back at him with concern.
<u>The carrier is an unfamiliar adult who approached to Tyra's niece (by smiling) under a situation that doesn't take place very often</u> (the mail carrier stepping inside the house) <u>so the baby reacts with concern.</u> This is an example of Stranger wariness.
