Weathering and erosion played a big role in forming the grand canyon. The rock was being weathered, most likely mechanical weathering, and then it eroded away. Think of a pebble that is in running water. When you pick it up, it is smooth, right. But before, it was pointy. So, the grand canyon was once a big rock, and weathering broke through it making it one of the wonders of the USA.
Answer:
B
Explanation:
Directional selection tends to evolve towards one specific trait. In this example, white rabbits no longer have a competitive advantage because of disappearing snow. This means they are more easily spotted by predators, resulting in reduced fitness and less chance they will live to reproductive age and pass their recessive white alleles on.
Natural selection will favor the gray colour allele, increasing the frequency oft this previously rare allele.
The submarine will most likely find data that shows the highest pressure data and the lowest temperature data (unless of course it's near a hydrothermal vent). This is because due to the depth there's a lot more water above it putting a lot of pressure on the sub, and very little sunlight to heat up the water.
Answer:
The correct answer is fungi.
Explanation:
Fungi are the eukaryotic organism but they can be present in unicellular and multicellular form. They are different from plant, animals, and bacteria. They are heterotrophic organisms and do not conduct photosynthesis. Their cell wall is made up of chitin.
Most of the fungi are saprophytes which means they take their nutrition from the dead and decaying organism. So fungi play an important role in clearing the waste organic material from the environment so they help in bioremediation. All members of fungi comes under a separate kingdom fungi.
