Answer:
endoplasmic reticulum (ER)
Answer:
It is because of Various things that we do, If we did not exist, several animals that went extinct because of us, would have thrived, If it wasn't for us filling the sky with so much CO2's, we wouldn't have the Earth heating up even more. Also, other things that we do such as Urbanization, Desertification, and Deforestation. All of these words will be defined under this text.
Explanation:
Deforestation: When humans cut down too many trees can result in habitat loss/ more CO2's
Desertification: When land used to be a grassland but humans used too much of a resource and turned it into a hot, sandy wasteland.
Urbanization: When you take land and fill it with tons of buildings, homes, and businesses. This can result in over-crowding, and spreading of diseases.
One property is it's volume. I am not sure if the second
Until well in the 60ties, the luminous dials of wrist watches and alarm clocks were marked with luminous paints containing Radium (Ra-226) or Promethium (Pm-147). These kind of watches are no longer manufactured today. This is not due to the radiation exposure to the persons wearing the watches but because of the radiological risk for the persons manufacturing them.
Hope this helps
From the periodic table as well as the patterns and trends on the table, the correct option are:
- the best conductor of electricity is Titanium; option A
- the most reactive element is oxygen; option C
- the elements that has the highest electronegativity is oxygen; option C
<h3>What is the periodic trends in the periodic table?</h3>
Periodic trends in the periodic table refers to the variation in character which is observed in the periodic table as one moves across the periodic table from left to right across a period or down a group in the periodic table.
The periodic trend observed is that reactivity of metals increase down a group and from right to left across a period.
For non-metals, reactivity of non-metals increase from down to top in a group and from left to right across a period across a period.
Considering the given questions;
1. From the periodic table as well as the patterns and trends on the table, the best conductor of electricity is Titanium since it is the only metal in the list.
2. The most reactive element is oxygen because it is a non-metal found to the top-left of the periodic table.
3. The elements that has the highest electronegativity is oxygen because it is a non-metal found to the top-left of the periodic table.
