<span>The diameter of a human hair is more than 1000 times the diameter of a single pollen grain. Pollen grains of pines, firs, and spruces are winged. The smallest pollen grain, that of the forget-me-not (Myosotis spp.), is around 6 µm (0.006 mm) in diameter. Wind-borne pollen grains can be as large as about 90–100 µm.</span>
Answer:
O sinkholes, caves, and hot springs chemical and physical actions of groundwater.
Explanation:
Sinkholes, caves, and hot springs are formed from the actions of groundwater. The rock is made up of lime below the surface of sinkholes. These lime react with underground water and dissolve it which soften the rock and causes sinkholes. Caves are also formed when the water dissolve the limestone present in the rocks of the cave and slowly the degradation of rock will occur and caves are formed. Hot springs are formed when the groundwater is heated by the magma of the earth crust.
Answer:
Transcription.
Explanation:
Transcription may be defined as the process of formation of RNA molecules from the DNA template. Specific enzymes and chemical factors are required for the process of transcription.
During transcription, the RNA copy is made from the DNA template. Three main different types of RNA are messenger RNA, transfer RNA and ribosomal RNA.
Thus, the answer is transcription.
