Answer: Option (a) is the correct answer.

Explanation:

When there occurs sharing of electrons between two chemically combining atoms then it forms a covalent bond.  Whereas is there occurs transfer of electrons from one atom to another then it is known as an ionic bond.

As, atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2.  

Hence, in order to become stable in nature it will donate its valence electrons to oxygen atom.  

As atomic number of oxygen is 8 and its electronic distribution is 2, 8. So, in order to attain stability it will readily react with magnesium atom.

As a result, MgO compound will be formed due to transfer of electrons from magnesium to oxygen atom.  Therefore, an ionic bond will be formed.

Thus, we can conclude that ionic bond holds these atoms of both magnesium and oxygen together.

If the net force an object at rest is zero the object will remain at rest. <br> True or false
FromTheMoon [43]

True

Explanation:

If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.

 Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "

  • If no net force acts on a body, it will forever remain at rest.
  • The force on a body causes its motion and acceleration.
  • A body will continue in uniform motion if no external force acts on it.

In what stage of the cell cycle are the daughter cell produced
marshall27 [118]
The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
So it is the very last stage!

​(f) contact a local hospital and ask them the percentage of the population that is blood type o. why might the results​ differ?
Fudgin [204]
Contacting a local hospital and asking them the percentage of the population that has blood type O will generate different results. 

The factors that we have to consider why there is differing results are:
1) location of the hospital
2) nationality of their patients
3) number of their patients

I am assuming that the population that question is referring to is the number of patients in the local hospital. The bigger the population, the smaller the effect a unit has on the whole and vice versa. 

I read an article that states that 37% of the U.S. population has O+ blood type. These people are usually of Hispanic descent or some Asian descent. So, if a hospital is in a locality that has a majority of Hispanic or Asian patients, its percentage will be higher than a hospital that is located in a Caucasian-populated area. 

Aside from Type O+ (most common), blood types also include: O-, A+, A-, B+, B-, AB+, and AB- (rarest blood type)
