Fossils that contain organic material can be dated based on the radiocarbon dating method. Carbon14 is an isotype of carbon. The Amount of carbon14 in the bone or rock should determine how old it is.

"skeletons are good age markers because teeth and bones mature at fairly predictable rates. For toddlers to teenagers up to age 21, teeth are the most accurate age indicators. Some of the best indicators of adult age are in the pelvis."

Coin tosses can demonstrate the effects of genetic drift. Imagine that heads and tails are two alleles in a population. Consider
nydimaria [60]

Answer:

Smaller populations have a greater chance of having one allele expressed disproportionately.

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events.  Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent. Thus limiting the genetic content of a particular group, restricted to the prevailing individuals.

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals. In this scenario, smaller populations will have a greater chance of having a disproportionately expressed allele as the number of members is reduced. We can also see this effect if by using a coin we imagine that heads and tails are two alleles in a population and each coin toss represents one member of that population.

3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce.

4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin.
