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.

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

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.

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.

Hexagonal close-packed (HCP) structures exhibit ABCABC packing.

AIDS is caused by the Human Immunodeficiency Virus (HIV), which is a virus.

Cholera is caused by the bacterium Vibrio cholerae.

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis.

Ferns have a dominant sporophyte generation, which is the leafy part of the plant.

All of these plant groups exhibit alternation of generations, which includes both haploid (gametophyte) and diploid (sporophyte) phases.

All vascular plants, including angiosperms, gymnosperms, and pteridophytes, exhibit alternation of generations with both gametophyte and sporophyte stages.

Liverworts are characterized by having a thallus, which is a flat, leaf-like structure.

Angiosperms are characterized by having seeds enclosed within a fruit, which is a key feature of this group.

Parenchyma tissue is primarily involved in storage, as it can store starch, oils, and water.

Meristematic tissue is responsible for the growth in length of stems and roots through cell division.

Apical meristem is responsible for the primary growth in length of the plant.

Apical meristem is responsible for the growth in length of the plant, found at the tips of roots and shoots.

Pteridophytes have a dominant sporophyte generation, while bryophytes have a dominant gametophyte generation.

Natural rubber is formed by the polymerization of isoprene.

Rubber is classified as an elastomer, which is a type of polymer that exhibits elastic properties.

A condensation reaction occurs when two monosaccharides combine to form a disaccharide, releasing water.

The reaction between 1-bromopropane and sodium cyanide is a nucleophilic substitution reaction, resulting in the formation of propanenitrile.
