The elbow is a hinge joint, allowing movement in one plane, primarily flexion and extension.

The shoulder joint is a ball and socket joint, allowing for a wide range of motion.

The shoulder and hip joints are ball and socket joints, allowing for a wide range of motion.

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

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

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.

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.

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

Cholera is caused by the bacterium Vibrio cholerae.

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

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

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

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.

Bryophytes can reproduce both sexually, through gametes, and asexually, through fragmentation or budding.

Ferns primarily reproduce sexually through spores, although they can also reproduce asexually.

Flowering plants primarily reproduce sexually through the formation of flowers and seeds.

Flowering plants can reproduce both sexually (through seeds) and asexually (through vegetative propagation).

Sponges can reproduce both asexually through budding and sexually by producing gametes.

Monocots typically have a fibrous root system, which consists of many thin roots.

Most cnidarians exhibit radial symmetry, allowing them to interact with their environment from all directions.
