1. Primary growth is the method by which roots and shoots are elongated in all vascular plants.
Contrary to animals, plants exhibit indeterminate growth, meaning that under ideal conditions and presence of resources, plants grow and add new organs continuously. Plants have two distinct types of growth: the primary and secondary growth. Primary growth is achieved through cell division and results in the elongation of the plant both above ground and below ground. Therefore, primary growth involves cell division at the tips of roots and shoots resulting in their elongation. 

2. Primary growth is accomplished by two cylinders of dividing cells called apical meristems.
Plants' indeterminate growth is achieved through specialized tissues which have continuous cellular division and growth and are called meristems. Apical meristems are found at the tips of roots and shoots and are responsible for the elongation of the plant's roots and shoots. Therefore, apical meristems are the main tissue responsible for primary growth.

3. Secondary growth is accomplished by groups of undifferentiated cells at the tips of the roots and shoots called lateral meristems.
Apart from primary growth, some plants also exhibit secondary growth, which involves the increase in the width and thickness of the plant. Secondary growth is achieved through lateral meristems, which are groups of undifferentiated cells with high cell division activity. The difference is that these cells grow outward, resulting in the widening of the plant. 

4. The majority of growth in width is due to increases in the number of cells added by the vascular cambium.
Lateral meristems are also called cambiums, a term referring to growth through the addition of tissue layers. There are two cambiums which are critical to secondary growth: vascular and cork cambium. Vascular cambium forms vascular tissue attributing to the plant's support and transport of water and nutrients. The cells of the vascular cambium divide and produce the secondary xylem and phloem. This causes a growth in width.

5. Cork is the method by which woody plants grow in thickness. 
As explained above, secondary growth is achieved through two cambiums (cork and vascular cambium). In woody plants, cork cambium produces tough and thickened cork cells which participate in the increase of the plant's thickness. In addition, cork cells protect and insulate the plant. More specifically, cork cells protect from pathogens, insects and incidents of fire and reduce water loss.

True, a retractable service pit cover can help other shop employees from falling into the pit while another technician is in the pit servicing a car.

Retractable service pit cover is a special cover made to cover service pit which aid inspection and repair of vehicle in an auto workshop.

Retractable service pit ensure safety of workshop technicians around service pits.Retractable service pits aid proper inspection of the beneath of the vehicleRetractable service pits enable the technician to have a close view of the vehicle in repair.The pit also serves as guide to short-eyed people or people to are not aware of the structure.In essence, the pit prevent against injury or death of workers and occupier.

In conclusion, the retractable service pit cover help other shop employees from falling into the pit even if they are aware of the structure.

Code:

#include <iostream>

using namespace std;

int main()

{

  int Car_Year;

  cout<<"Please Enter the Car Model."<<endl;

  cin>>Car_Year;    

 if (Car_Year<1967)

 {

cout<<"Few safety features."<<endl;

 }

else if (Car_Year>1971 && Car_Year<=1991)

{

cout<<"Probably has head rests."<<endl;

}

else if (Car_Year>1991 && Car_Year<=2000)

{

cout<<"Probably has antilock brakes."<<endl;

}

else if (Car_Year>2000)

{

cout<<"Probably has airbags."<<endl;

  }

else

{

cout<<"Invalid Selection."<<endl;

}

  return 0;

}

Output:

Please Enter the Car Model.

1975

Probably has head rests.

Please Enter the Car Model.

1999

Probably has antilock brakes.

Please Enter the Car Model.

2005

Probably has airbags.

Please Enter the Car Model.

1955

Few safety features.

Explanation:

We were required to implement multiple If else conditions to assign car model year with the corresponding features of the car.

The code is tested with a wide range of inputs and it returned the same results as it was asked in the question.

NTQ

Explanation:

The given sequence is

BHE : FLI : JPM

If is clear that, alphabets on first places are B, F, J. Difference between their place vales is 4.

B+4=F,F+4=J ; so alphabet on first place of next term of sequence is J+4=N.

Similarly, alphabets on second places are H, L, P. Difference between their place vales is 4.

H+4=L,L+4=P ; so alphabet on second place of next term of sequence is P+4=T.

Alphabets on third places are E, I, M. Difference between their place vales is 4.

E+4=I,I+4=M ; so alphabet on third place of next term of sequence is M+4=Q.

Therefore, the next term is NTQ.
