Answer: They are geographically widespread
Explanation: Markers of geological time refers to indicators or guide employed in the estimation and depiction of the geological time a particular rock deposit or event occurred. The markers above, the volcanic ash are particles ejected during volcanic eruption which involves the flow of very hot lava to the earth surface which cools and solidifies very rapidly. and index fossils are usually good markers of geological time because the are geographically widespread. This characteristic ensures that mapping deposits over a large geographic regions is possible due to the occurrence of these markers over a broad geographic region. Where markers do not posses wide geographic spread, it becomes very difficult to map. In addition to the above characteristics, both markers are also formed over a short period of time.
I think the answers Mutations
Answer:
If the father is heterogeneous, there is a 50% probability for a blood type A child and a 50% probability for a blood type O child. If the father is homologous, every offspring will be blood type A.

Answer:
Object 3
Explanation:
According to Newton's Law of Universal Gravitation, the mass of an object is directly proportional to gravitational attraction. This basically means that the greater the masses of the objects, the greater the gravitational attraction.
It also states that distance is indirectly proportional to gravitational attraction. This means that the farther they are apart objects are from each other the lesser the gravitational attraction.
Now taking your scenario, because the objects are equidistant, distance would not be a factor in the differences in attraction. But as you can see, object 3 has the least mass. This means that among all the objects surrounding object 1, it would have the least gravitational force.
