Answer:
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
Explanation:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Answer:
A sound wave with 15,000 Hz
Explanation:
Humans can averagely hear up too 20,000 Hz. So around 15,000 would make most sense.
Homozygous for allele A and heterozygous for allele B. So the answer would surly be D.
Answer:
the F1 generation
Explanation:
If two strains of true-breeding plants that have different alleles for a certain character are crossed, their progeny are called the F1 generation
Answer:
(Ba) and (BA)
Explanation: those could be one of the combinations if u put them on a punnet square
