Hi!
The correct options would be B & E.
Rock and granite are hard and tough materials that are allow very minor seepage of water, which is close to negligible which is why these materials have been employed as construction material in buildings.
Clay is relatively more permeable to water as compared to granite and rock, but still does not allow water to flow through easily as it has a low porosity and permeability to water.
Soil & Organic Layer (fertilizer), allow easy passage of water through them due to high porosity.
Hope this helps!
Answer: Solution 2 because the single substrate easily get transformed into products at the active site of any of the 100 enzymes.
Explanation:
Since Solution 1 has 1 enzyme to 100 substrate while Solution 2 has 100 enzyme to 1 substrate, catalysis of the single substrate to product will be greater in Solution 2 as the enzyme will compete to quickly transform the single substrate in its active site unlike solution 1 will 100 substrates taking more time.
The other biologists and scientists thought his theories were bogus
Answer:
The correct answer is D increasing the activity of protons pumps that lowers the pH of the cell walls allowing cells to elongate.
Explanation:
The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.
The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.
Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.
Answer:

Explanation:
The pellets from a barn owl often contain the remains of 4 or 5 small animals. Let's assume an average of 4.5 animals per day.
1. Animals per week

2. Animals per year

3. Animals per month
