volcanic activity
Answer: Option D.
<u>Explanation:</u>
Volcanoes are regular along tectonic plate boundaries where oceanic plates sink underneath different plates. As a plate sinks profound into a subduction zone, it warms and starts to soften, shaping magma.
Volcanoes are likewise basic along structural limits where plates pull separated, permitting magma to ascend from the mantle.Volcanoes are generally basic in these geographically dynamic limits. The two sorts of plate boundaries that are well on the way to create volcanic movement are divergent plate boundaries and convergent plate boundaries.
If this is true, than the animal that is embedded in this fossil most likely would have had opposable thumbs, which are crucial for using tools and climbing trees.
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.
Answer:
Circadian rhythms help determine our sleep patterns. The body's master clock, or SCN, controls the production of melatonin, a hormone that makes you sleepy. It receives information about incoming light from the optic nerves, which relay information from the eyes to the brain.
The energy originated from the animal when it was alive
