Water erosion is usually what people think of, but ice, wind and gravity can also cause erosion.
Water erosion is usually along rivers. As the water moves quickly by it rubs on the rock and dirt, causing rivers to slowly get wider.
Ice erosion is caused by glaciers. Sometimes it's a glacier rubbing against land, and there's a lake that was made by a glacier making it's way onto land and then melting.
Wind erosion is a big problem in fields and large open plains with loose dirt. The wind just blows all the dirt away.
Gravity can cause erosion and cliffs. Sometimes along a mountain or cliff the rock won't be able to hold itself up anymore, and gravity will pull it down.
Your answer would be all of them. Wind, water, ice, and gravity.
The process of turning off and on of genes is known as gene regulation.
Explanation:
When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.
The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.
Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
Answer:
C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.
Explanation:
C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.
This statement not true for a following reasons.
Firstly, creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.
Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.
