The knee joint is classified as a hinge joint, allowing movement primarily in one plane.

A p-n junction is formed when p-type and n-type semiconductors are joined together.

A U-shaped valley is formed by the erosion of rock by glaciers, which carve out the valley's characteristic shape.

In opposite leaf arrangement, two leaves grow at each node directly across from each other.

In opposite leaf arrangement, two leaves grow at each node directly across from each other.

A convex lens is used to correct hypermetropia (farsightedness) as it converges light rays before they enter the eye.

Hyperopia is corrected using a convex lens, which converges light rays before they enter the eye, allowing for clear vision of nearby objects.

A convex lens is used to correct hyperopia (farsightedness) as it converges light rays before they enter the eye.

Linearly polarized light consists of waves that oscillate in a single plane, making it completely polarized.

Lasers emit light that is completely polarized because the light waves are emitted in a single direction and phase.

Cellulose is a carbohydrate and a major component of plant cell walls.

A Topographic Map shows the physical features of an area, including mountains, valleys, and plains.

An identity matrix is defined as a square matrix with all diagonal elements equal to 1 and all other elements equal to 0.

A matrix where all elements are zero is called a zero matrix.

A scalar matrix is a square matrix in which all the elements are equal to the same scalar value.

A skew-symmetric matrix is defined by the property A = -A.

The reaction of 2-bromopropane with a strong nucleophile typically follows the SN2 mechanism due to steric hindrance.

The reaction of haloalkanes with strong nucleophiles typically follows the SN2 mechanism, which involves a single concerted step.

Tertiary haloalkanes typically undergo the SN1 mechanism, which involves the formation of a carbocation intermediate.

Learning a new language primarily involves semantic memory for vocabulary and grammar.

RAM (Random Access Memory) is used for temporary storage of data that the CPU needs while the computer is running.

The hip joint allows for flexion, extension, abduction, adduction, and rotation, making it a versatile joint.

Isometric contraction occurs when the muscle length remains the same while tension is generated.

Smooth muscle is involuntary and found in the walls of internal organs, facilitating functions like digestion.

Cardiac muscle is responsible for the involuntary contractions of the heart, leading to the heartbeat.

Skeletal muscle is responsible for voluntary movements, while smooth and cardiac muscles are involuntary.

Cardiac muscle is the type of muscle tissue found in the heart, responsible for pumping blood.

Skeletal muscle is striated and under voluntary control, allowing for conscious movement.

A geosynchronous satellite typically has a circular orbit to maintain a constant position relative to the Earth's surface.

The body-centered cubic (BCC) structure features body-centered packing, where one atom is at the center of the cube and eight atoms are at the corners.
