The right option is; d. Runoff describes water movement and infiltration describes water storage.
Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.
Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
<h2>Answer:</h2>
The correct answer is option B which is the melting points of sample Q and sample R are the same.
<h3>
Explanation:</h3>
- According to the question description, Plastic sample Q melted at 20 mins and sample R melted at 10 minutes while providing the heat double than sample Q.
- Melting point of a substance is the temperature on which the substance changes its phase from solid to liquid.
- This temperature is actually the amount of heat. The melting can be reached a point early by giving large amount of heat.
- Hence the melting points will be same, just time to reach that points will be different according to amount of heat given.

Answer:
B
Explanation:
it will take too long to count every fire coral in a 280 square km area, B is the most appropiate technique
Answer:
given, mother and father are heterozygotes.
let, father has B blood group and mother has A blood group.
then their heterozygous genotypes are --
father = iB, iO and mother = iA, iO
punnett square will be,
iB iO
iA iA iB iA iO
iO iB iO iO iO
the genotypes of their progeny will be, iAiB , iAiO ,iBiO and iOiO
and phenotypes will be 3 are heterozygous and 1 is homozygous.
