In all body cells, with the exception of a few, mitochondria are present. Depending on the function of that type of cell, there are typically several mitochondria present in one cell. Mitochondria are found along with other organelles of the cell in the cytoplasm of cells.
1. Temperate grassland and savanna have grasses as the predominant plant form.
2. Both temperate grassland and savanna mostly have animals that feed on grass [grazer] as the primary consumers.
Also, the two vegetation are prone to fire incident and both have been impacted by agriculture.
A physical change is a change which only affects the form of a substance, but not its chemical composition. So, a physical change in terms of particle arrangement states that particles do not change apart from gaining or losing energy. It can be explained using the examples of freezing and melting.
When a substance is solid, its particles like atoms and molecules are very tightly packed. These cannot move freely but when a substance is in liquid or gaseous state, the particles are loosely packed and can move freely. So when water is solid the particles are tight but when it is in liquid state same particles can move faster. Hence, particles are same but their energy has changed.
