Answer:
Explanation:
D
Answer:
1) Conduction.
Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.
2) Radiation
The heat on the glass surface gets radiated into the chair which causes the chair to warm up.
3) Convection
The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.
1. Hot coffee warms the spoon through conduction,
2. a chair warms through radiation from the fireplace,
3. decorative lamp globs rise through convection.
1. Hot coffee is stirred with a spoon, the spoon gets hot due to conduction.
2. A chair is placed several feet from a fire in a fireplace. The fireplace has a glass screen. The side of the chair facing the fireplace gets warm because of radiation.
3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to convection.

The mineral gets broken down over time.
The mineral erupts from a volcano.
The mineral dissolves in hot water.
Answer:
The correct answer is option A, that is, the atoms in the mineral get rearranged.
Explanation:
With time, and under immense pressure, the atoms of a substance can become reorganized, producing a novel substance. For example, the carbon present underground in the form of coal encounters with intense pressure, that further gets rearranged or reorganized to convert into a diamond, that is, the atoms of coal get rearrange themselves with time to produce a diamond.
B. cities
C. forests
D. industrial areas
Hedgerows have created new ecosystem within Britain's farms which are patchwork quilts.
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of the dead plants and animals by action of microbes nutrients are released back in to the soil.

d. circular
Answer:
circular
Explanation:
Plasmids are small, circular extrachromosomal DNA molecules that replicate independently of the chromosomal DNA. They usually carry at least one type of gene that is beneficial to the host organism. They code for resistance genes in bacteria.
