Weathering, plate movements, and volcanoes destroyed many of the craters. The factors contribute to the lack of evidence of heavy bombardment of earth. This evidence was subjected or, if not subjected, weathered; since Earth was and still is a "living" planet, meaning a planet with active plate tectonics and an active hydro/atmosphere. This activity is in contrast to the Moon, where plate tectonics stopped shortly after its formation and where a hydro-atmosphere could never form. Both because the Moon was simply too small to sustain plate tectonics and to keep volatility with him/her.
Answer:
d. Ao x oo
Explanation:
The other crosses with A would all result in complete dominance because the alleles (other than A) from the other parent are dominant. Because option D. crosses a h o m o zygous parent with a recessive trait, the cross could produce a child with blood type A.
Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. An infected cell produces more viral protein and genetic material instead of its usual products.

Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
