Toxins in the soil would enter through the root system first.
Answer: Option A.
Pure solvent diffused through a membrane but solutes do not.
Explanation:
Osmosis is process where solvents or molecules move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane which tend to balance the concentration of solutes. Osmosis is passive transport i.e it does not require energy for movement.
Because at that point, the egg would already be fertilized. Now in cases like identical twins, two sperm must enter the egg at the exact same time.
Answer:
No Oxygen will be consumed, and there will also be no ATP production.
Explanation:
No Oxygen will be consumed, and there will also be no ATP production.
The blockage of the binding of Oxygen with cytochrome C enzyme occurs, and this greatly decreases the cellular uptake of oxygen.
Therefore, in the presence of cyanide, ATP production is inhibited due to blocked oxygen utilization.
The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
