In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.
1.Water evaporates in the presence of sunlight.
(hydrosphere)
2.Volcanoes release a large amount of gases and other matter during eruption.
(lithosphere)
3.Lightning causes nitrogen molecules to be split and carried by rain.
(hydrosphere)
4.Plants release water vapor through their leaves during transpiration.
(biosphere)
Hope this helps!
Answer:
The correct answer is option b. "by their dominant processes that formed them".
Explanation:
Mountains are classified in four different types according to the dominant processes that formed them. The four different types of mountains are: upwarped mountains, fault-block mountains, folded mountains and volcanic mountains. Upwarped mountains are produced by a differential of pressure from inside the Earth that pushed the crust upwards. Fault-block mountains were formed by tectonic plate movement, folded mountain when two plates move together, while volcanic mountains are formed by a crack in the Earth known as volcanic vent.
The question is incomplete as it does not have the options which are:
A. More; more; gravitropism
B. More; less; phototropism
C. Less; more; gravitropism
D. Less; less; phototropism
Answer:
B. More; less; phototropism
Explanation:
Auxin is a hormone which is involved in the plant growth and the development by increasing the flexibility of the cell wall of the plant.
In the given question, the vertical root is rotated to the horizontal orientation which will be sensed by the roots and the roots will then redistribute the auxin in the roots.
The auxin will be transported to the lower areas but the growth of the root in the lower portion will be lowered as a result of which root will grow downward. This is considered a condition called positive gravitropism or negative phototropism.
Since the distribution of auxin is dependent on the presence or absence of light therefore this phenomenon will be referred to as the phototropism.
Thus, Option-B is correct.
