Answer:
Mechanical Weathering
- caused by freezing and thawing of of water.
- caused by the movement of agents such as glaciers and wind.
Chemical weathering
- caused by processes such as corrosion, hydrolysis and dissolution.
- caused by precipitation reacting with minerals in the rock.
- creates new substances such as clay and salts.
Answer:
Yes
Explanation:
Yes, it is possible. If the woman would have blood AO and the father BO. This would mean there is a 25% chance the child could be OO blood. They would receive an O allele from their mom and an O allele from their dad, in all other cases the O allelle is recessive so AO would be A blood type and BO would be B blood type. AB would be type AB.
B O
A AB AO
O BO OO
Answer:
what exactly do you need help with?
When Amanda poured some of the liquid in a test tube, she noticed that the edges if the water curved upward, which is an illustration of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is a proof of cohesion.
When Amanda added table salt to the first test tube and shook it, she noticed that the liquid had dissolved the solute.
All of these observations are suggesting the existence of covalent bonds.
Pol determined that the pH of the sample is 7 that indicates that the sample is neutral.
Based on all the proof gathered by Pol and Amanda, the unknown liquid is water.
