Answer:
Water erosion can contribute to pollution.
Explanation:
Remember that pollution refers to the introduction of contaminants in natural environments causing negative changes in the ecosystem.
Water erosion is possible because of the sediments that carries and erode soil surface. Also, it can contribute to water contaminations because of the different types of sediments can carry, finally causing pollution.
Answer: it's 3CO2+4H2O+Energy
Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.
The reaction of its complete combustion by the presence of oxygen is:
C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)
As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.
While there is no graph provided and I cannot find the graph online, I will base my answer through theory.
In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
