Answer:
The presence of high temperature and pressure, soil as a medium and also microbes are the factors that determine if animals and plants will form fossils.
Explanation:
As plants as well as animals dies in moist condition, and when buried inside the mud or silt. The soft tissues present starts degrading leaving behind the hard bones and also shells. Over the period of time various layers gets formed over it. As a result of high pressure and temperature fossils are formed. In case of animals the mineralized shell i.e. trilobite and ammonite form the fossils. It takes around 10,000 years for the formation of fossils the time period is minimum it may vary according to the species.

Answer:
Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.
Answer:
:)
Explanation:
The main artery from the heart (aorta) becomes thicker, stiffer, and less flexible. This is probably related to changes in the connective tissue of the blood vessel wall. This makes the blood pressure higher and makes the heart work harder, which may lead to thickening of the heart muscle (hypertrophy).
Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
