Answer:
C. A steep slope
Explanation:
Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.
Agents of erosion are wind, water, glacier and gravity.
Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.
On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.
Fungi are effective decomposers, saprophytic fungi grow towards their food source, mycelia produce extracellular enzymes to digest food outside of hyphae, saprophytic fungi like miners: they blast away lignin to expose cellulose, fungi use other enzymes to degrade cellulose to glucose.
Hope this helped :)
Have a great day
If DNA is found at a crime scene it can help locate people that were at the crime scene. If the criminal has committed crimes before their DNA will already be in the police system. If not they can take samples from suspects and pinpoint who committed the crime.
Answer:
They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
