Answer:
Physical change
Explanation:
When melting, it absorbs heat from the surround and changes the physical state (solid to a liquid). no reactions are happening, liquid ice molecules will exist the same as in solid ice.

What is the stage in the life cycle of plants when the plant is able to produce seeds, cones, or spores called?
Adult stage
Embryo stage
Final stage
Sprouting stage
PLS HELP I WILL GIVE BRAINILITS
The adult stage is a stage in the life cycle of plants when the plant is able to produce seeds, cones, or spores. The correct option is (a).
The plant has now reached full maturity and is ready to reproduce at this point. Depending on the species of plant, it grows flowers, cones, or other reproductive organs, and it creates seeds, fruits, or spores. For the plant to reproduce and complete its life cycle, these reproductive structures are essential.
Angiosperms, the most varied class of plants, are made up of all the common flowering plants we see every day. The development of flowers, which are reproductive organs tailored for sexual reproduction, occurs during the adult stage of a flowering plant's life cycle.
Hence, the adult stage is a stage in the life cycle of plants when the plant is able to produce seeds, cones, or spores. The correct option is (a).

What is the difference between the life cycle of a sunflower and the life cycle of a pine tree?
The pine tree and the sunflower both produce seeds during the sprouting stage.
The pine tree produces seeds in the flower, and the sunflower produces seeds in the cone.
The sunflower and the pine tree both produce seeds during the seedling stage.
The sunflower produces small seeds in the flower, and the pine tree produces seeds inside the cone.
The difference between the life cycle of a sunflower and the life cycle of a pine tree is the sunflower produces small seeds in the flower, and the pine tree produces seeds inside the cone. Option (4) is correct.
Sunflower's life cycle is given as:
Sunflowers' life cycles start with their seeds. The seed has the genetic material required for development and growth.
Germination: A young seedling appears from the soil when the seed is given the ideal conditions (enough water, sunlight, and a suitable temperature).
Stage of the seedling: At this stage, the seedling develops into a young plant with leaves and a fragile root system. The sunflower keeps evolving and gets taller at this stage.
Stage of Vegetation: As the sunflower develops, it moves into the stage of vegetation, which is characterized by substantial leaf growth and stem elongation.
The Pine Tree Life Cycle is given as:
Pine tree seeds, which are found inside pine cones, are the source of the tree's life. Each scale of the cone's scales contains a seed, which is often winged.
Pine cone scales split open to release the seeds when the right conditions are present, which is known as germination. In suitable situations, seeds can germinate even after falling to the ground.
Both sunflowers and pine trees generate seeds, but the main distinctions are between the reproductive structures (flowers vs. cones) and the means of seed distribution (seeds in the flower head vs. seeds within cones with wings). A stage of cone production is also experienced by pine trees, but not by sunflowers.
Hence, the difference between the life cycle of a sunflower and the life cycle of a pine tree is the sunflower produces small seeds in the flower, and the pine tree produces seeds inside the cone. Option (4) is correct.
