Convection is the transfer of heat/thermal enrgy by the movement of a fluid(either a liquid or gas).
B:Oxygen and silicon
Explanation:
Most minerals on the earth's surface contains oxygen and silicon. Silicon and oxygen are the most abundant elements we find in the rock minerals on the earth surface.
- Silicon and oxygen forms the SiO₄⁻ tetrahedron through which several minerals are formed.
- These minerals built on the network of the tetrahedron are referred to as silicates.
- Several silicate minerals are known:
- Quartz
- Feldspars
- Olivine
- Biotite
- Pyroxene

In physics, there is a rule that the heat always travels from the hotter object to the cooler object. In this case, as the iron is hotter than the shirt, the heat will travel from the iron to the shirt.
The answer would be the amino group and the carboxyl group
hope this helpssss
True
Carbon monoxide is a primary pollutant which no odor results from incomplete combustion of fuel. The man sources are gasoline and burning of biomass.
Depending on the source of emission, pollutants can be classified into two groups that is primary and secondary pollutants.
A primary pollutant is emitted in the atmosphere directly from a source. It can be either natural sch as volcanic eruptions, sandstorms or man-made that is due to industrial and vehicle emissions. Examples of primary pollutants are nitrogen oxides, carbon monoxide and particulate matter.
Secondary pollutant is due to interactions between primary and secondary pollutants. These can be chemical or physical interactions. Examples are photo-chemical oxidants and secondary particulate matter.
Therefore, carbon monoxide CO is a primary pollutant.
