-Headlands form in areas of alternating hard and soft rock. Where the soft rock erodes bays are formed either side of the headland.
-As the headland becomes more exposed to the wind and waves the rate of its erosion increases. When headlands erode they create distinct features such as caves, arches, stacks and stumps.
C, a headland. Bands of resistant rock along the coastline will be worn away at a slower rate than the softer rock layers either side of it, so a headland (section of land that appears to stick out into the sea when much of the cliff has retreated) is formed.
Thymine is one of the four nucleobases that pairs with adenine to make up DNA, also called 5-methyluracil. It is replaced by uracil to make RNA molecules during transcription.
Theferore the unknown chemical analyzed was DNA because thymine is found in DNA and not in RNA molecules.
Since the genes are located in the nucleus of a cell which has being removed (but some genes are still located in the mitochondria of the ocyte) from its ocyte to fuse it with with another nucleus. Since the cell follows a maternal inheritance of gene, it would have a small head because of the presence genes in the mitochondria.
