Answer:
A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.

State in words what Einstein’s equation represents.
Explain why Einstein’s equation is so important.
How does Einstein’s equation relate to the energy produced in nuclear reactions?
Answer:
hope this helps, im sorry if it dosent
Explanation:
1-
An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
2-
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If the mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.
3-
Einstein's greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously
4-
The change in mass is related to the change in energy according to Einstein's equation: ΔE = (Δm)c2. ... The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles.

Wegener's theory of continental drift? Explain your answer.
Answer:
Explanation:
It does not support Wegener's theory of continental drift. Africa and South America were the part of a same land mass at one time, which then got separated into two different land forms called North America and South America and drifted to different locations other than the one from where they originated. This occurred due to continental drift. The evidence of this phenomena can be observed in fossils that were found to be same in both land forms. This depicts that same type of organisms were living in both land forms. Hence, gives the evidence that land forms were related.

How is oxygen carried from the lungs to the tissues?
a. It binds to a protein called hemoglobin in red blood cells
b. It is carried by cilia through the bronchioles
c. It leaves the alveoli and enters mucus
d. It leaves the bronchi and enters the capillaries
Answer:
It binds to a protein called hemoglobin in red blood cells.
Explanation:
I took the quiz.
Oxygen gas is carried in the body from the lungs to the tissues by binding to a protein called as hemoglobin in red blood cells. Thus, the correct option is A.
What is Hemoglobin?Hemoglobin is abbreviated as Hb or Hgb. It is the iron-containing oxygen-transport metalloprotein which is present in the red blood cells of almost all the vertebrates as well as the tissues of some of the invertebrates.
Hemoglobin is the main protein in the red blood cells which carries oxygen gas to body's organs and tissues and it transports carbon dioxide gas from the different body organs and tissues back to the lungs.
Therefore, the correct option is A.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world and above this limit causes adverse affect.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..
