Hello! mark me brainliest please
Sediment hardens into rock. √
Sediment is eroded from rock.
Organisms are buried under sediment. √
Organisms' shapes are preserved in rock. √
Organisms' soft tissues and bones are preserved.
Explanation:
A mold fossil is a type of fossil that is formed when an organism dies and is buried in sediment such as sand or clay, the sediment hardens to rock and the organism decomposes leaving an empty space or an imprint in the rock.
The question is incorrect so the answer consists of the genetic context of meiosis.
Answer:
Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.
In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.
The deserts are the regions of the lands, where there is a little precipitation and the temperature is generally too high during the day.
In the desert biome, the animals are adapted to dissipate heat to the environment, which make them remain cooler in the hot days. They have long appendages and long extremities, such as hear, which help them in constantly transferring the heat in their surrounding. Some animals lack fur, which allow them to remain cool, as the presence of fur would not allow the dissipation of the heat to the atmosphere.
The tundra biome is very cold, and the animals living there must have the tendency to trap heat to remain hot in the cold climate. All the desert animals are adapted to dissipate heat to the environment, so, they cannot trap heat, which makes them unfit survive in colder climates.
