Explanation

Ohm's law, description of the relationship between current, voltage, and resistance.

The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials.

Explanation

Chlorophyll, the pigment responsible for photosynthesis in plants, features a porphyrin ring structure at its core.

This ring is composed of four smaller pyrrole rings linked by methine bridges.

A magnesium ion is centrally located within this porphyrin ring, held in place by bonds with nitrogen atoms from the pyrrole rings.

Explanation

Ringed Planet is the nicked name for Saturn

Saturn is the second-largest planet

The largest moon of Saturn is Titan 

Explanation

In bryophytes, the gametophyte generation is dominant.

This means the leafy, green, haploid structure that is typically seen is the gametophyte, which is the most visible and longest-lived part of the bryophyte life cycle.

The diploid sporophyte is generally smaller and dependent on the gametophyte for survival.

Explanation

The cell wall of oomycetes is made of cellulose. 

Oomycetes, also known as water molds, are distinct from true fungi in that their cell walls are composed primarily of cellulose and glucans, rather than chitin which is the primary component of fungal cell walls.

Explanation

• Vitamins A, D, E, and K are fat-soluble vitamins.
• Fat-soluble vitamins are absorbed by the body along with dietary fats.
• They are present in foods that contain fats.
• The body stores these vitamins in the liver and fat tissue when they are not in use. 
• Megadoses of fat-soluble vitamins can be toxic.

Explanation

• Infrared waves are used in night vision equipment.
• They detect heat emitted by objects.
• It allowing visibility in low-light conditions.

Explanation

When an object is placed between the focus and centre of curvature, the concave mirror can form an image larger than the actual object.

Fans help by replacing hot and humid air with cooler, dry air that allows for more evaporation. Cold air evaporates sweat and creates a wind-cooling effect that cools us without affecting room temperature.
