The correct answer would be c. Ball and socket joints.
The Ball and socket joint is one of the types of synovial joint in which the round or ball-shaped end of one bone and cup or socket-like depression of other bone are complementary in nature.
The ball of one bone fits into the cup of other bone.
It provides greater freedom of movement as compared to another type of joints.
The distal bone can move around in a various number of axes all of which have a common center.
It is primarily present in the hip and shoulder joint of mammals.
Answer:
The correct order of formation of cDNA or complementary DNA are described below.
Explanation:
The DNA that is synthesized from mRNA with the help of reverse transcriptase enzyme is known as cDNA or complementary DNA.
Formation of cDNA
Step 1 Mature RNA is isolated
Step 2 Reverse transcriptase provided with a primer,synthesize a strand of cDNA without introns.
Step 3 The mRNA is hydrolyzed by raising the pH.
Step 4 A primer site is created on the single stranded cDNA molecule.
Step 5 A complementary DNA strand is synthesized forming double stranded cDNA molecule.
The largest vein in an animal's body is in fact the Vena Cava.

Answer:
Epicenter
Explanation:
The release of energy causes shaking at the ground surface. The location inside the Earth where an earthquake begins is called the focus (or hypocenter) of the earthquake. The point at the Earth's surface directly above the focus is called the epicenter of the earthquake.
