Explanation; -A water molecule can act as an acid or a base even in a sample of pure water. It acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide.
The answer is lag. The number of bacterial cells doubles at a constant, exponential rate during log phase, while growth rate and death rate are the same during stationary phase. The fourth phase is the death phase, when the rate of cell death is faster than the population growth.
For most children, the ability to recognize oneself in the mirror occurs around 18 and a half months. Towards their growth, they actually start to self-admire and feel embarrassed at 12 months, and between 14-20 months they demonstrate avoidance behaviours. As they continue to age to 20-24 months their self-recognition also improves to 65%
Answer: Gill cover, lateral line, and caudal fin.
-The <u>gill cover</u> is a bony plate located outside of the gills, and is used for protecting the organism's gills. Most bony fishes have one.
-The <u>lateral line</u> is a sensory stem that goes along the side of the fish's head to the base of the tail, which is used for sensing electrical vibrations in the water. Most of all fish have this, including sharks.
-The <u>caudal fin</u> is the tail of the fish. It's used for propulsion and quick accelerations in locomotion. Most fish have one.
Hope this is helpful ^^
