Because arteries have to have thick walls for use of protection. Its when you get to veins where the walls get thinner. And the use of the heart is to pump blood to all of the cells and organs in the body so it would be to transport blood away from the heart.

i.e. 

Arteries = Away from the Heart 
Veins = Back to the Heart.

A sarcomere is the basic unit of striated muscle tissue. It is the repeating unit between two Z lines.

Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis. Muscle fibers contain numerous tubular myofibrils. Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes.

A muscle fiber from a biceps muscle may contain 100,000 sarcomeres.

The carbon arc lamp was the first widely-used type of electric light and the first commercially successful form of electric lamp.

Here are the Carbon Arc Lamp Uses :

-Super bright light, capable of lighting a large length of street or a large factory interior.

-Was the ONLY electric light available to light large areas from 1800 - 1901.

-Was cheaper to light streets with the arc lamp than gas or oil lamps.

Civil Services Day is celebrated in India every year on 21st April. The Union Home Minister Shri Rajnath Singh inaugurated the two-day 11th Civil Services Day program (20-21 April) in New Delhi.

Bond Order  = 1/2[ Nb - Na]

where

Nb = Number of electrons in bonding molecular orbitals.

Na = Number of Electrons in antibonding molecular orbitals

Bond Order of N2⁺:

Total number of electrons: 13

Electronic Configuration= :σ1s² σ*1s² σ2s² σ*2s² π 2py² [π2pz² σ2px1 ]

Bond Order = [9-4]/2 = 5/2 = 2.5.
