Vaccination stimulates the immune system to develop active immunity against specific pathogens.

1,2-dichloroethene can exist in cis and trans forms, demonstrating geometric isomerism.

1,3-butadiene can exhibit geometric isomerism due to the presence of double bonds.

Glucose and fructose are structural isomers as they have the same molecular formula but different structures.

Butane exhibits structural isomerism as it can exist as n-butane and isobutane.

A delta is formed by the deposition of sediment carried by a river as the flow velocity decreases upon entering standing water.

A convex lens is used to converge light rays for hyperopic correction.

Natural light is typically unpolarized as it consists of waves vibrating in multiple planes.

Figural memory is useful for visualizing and manipulating pieces in a puzzle.

Figural memory aids in recalling visual layouts and spatial arrangements.

Type I fibers, also known as slow-twitch fibers, are more resistant to fatigue and are suited for endurance activities.

Slow-twitch fibers are known for endurance and have a high density of mitochondria for aerobic respiration.

Smooth muscle is involuntary and is found in the walls of internal organs, such as the intestines and blood vessels.

Smooth muscle is involuntary and is found in the walls of hollow organs such as the intestines and blood vessels.

Smooth muscle is involuntary and found in the walls of organs.

Skeletal muscle is striated and is under voluntary control, allowing for movement of the skeleton.

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

Motor neurons carry signals away from the central nervous system to muscles and glands.

White noise is the most commonly associated noise in communication systems, affecting signal quality.

A polar orbit allows a satellite to pass over the entire surface of the Earth as the Earth rotates beneath it.

A polar orbit allows a satellite to pass over the entire surface of the Earth as the Earth rotates beneath it.

A sun-synchronous orbit allows a satellite to pass over the same point on the Earth's surface at the same local solar time every day, as it is synchronized with the Earth's position relative to the Sun.

Ferns have a dominant sporophyte generation, which is the diploid phase of their life cycle.

All of the above groups exhibit a life cycle that alternates between haploid (gametophyte) and diploid (sporophyte) generations.

Parenchyma tissue is primarily involved in the storage of food and can also perform photosynthesis.

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

Meristematic tissue is responsible for the growth of plants as it contains undifferentiated cells that can divide.

Parenchyma tissue is primarily responsible for the storage of food and can also perform photosynthesis.

Collenchyma provides support and flexibility to the plant, especially in young stems and leaves.

Cross-pollination occurs when pollen is transferred from one flower to another flower of the same species.
