State the form of energy a)lost by the ball as it falls to the ground
b)gained by the ball as it falls to the ground.

Gravitational potential energy is the energy gained by an object as its height above ground level increases. As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls

explanation:

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
