Answer:
Lower gravitational force due to lower mass.
Explanation:
Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.
The period during which the presence of stromatolites decline is the Proterzoic period. Stromatolites are widely distributed sedimentary structures consisting of laminated carbonate or silicate rocks, produced over geologic time by the trapping, binding, or the precipitating of sediment by groups of microorganisms, primarily cyanobacteria.
Fruit flies share 75% of the genes that cause diseases with humans, so scientists can learn about human genetics by studying fruit fly genetics.
