True.
Soil retains water through pores, water has a high infiltration rate when going into granular soils but a very low infiltration rate when going into compact soils. For example, sandy soils that are often seen in Western Australia have very limited ability to retain water.
<span>In particular, their three membranes divide chloroplasts into three distinct internal compartments: (1) the intermembrane space between the </span>two membranes<span> of the chloroplast envelope; (2) the stroma, which lies inside the envelope but outside the thylakoid membrane; and (3) the thylakoid lumen.</span>
<span>A. No learning is necessary. In order for a behavior to be called innate, the action must be instinctively done towards a defined stimulus</span> without previous experience or practice. An example of innate behaviors is a young kangaroo (joey) climbing into its mother's pouch right after it was born.
Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
