Option D, groundwater adds water to lakes, rivers, and oceans, is the right answer.

Water held under the ground in the earth or in vesicles and cracks in the rock is known as the ground-water. Alternatively, the groundwater is the water found under the surface of the earth and in the clefts of rock deposits. The groundwater is usually less expensive, more accessible and less exposed to con-tamination than outside water. Therefore, it is used to meeting the need for public water supplies. Moreover, the groundwater adds water to lakes, rivers, and oceans, which becomes accessible to rural people and other living beings.

Why does incomplete dominance not support the blending theory of inheritance?
Nookie1986 [14]
Incomplete dominance can happen in flowers such as snap dragons where a red flower plant and a white flower plant have an offspring that is neither red nor white but is a mix so in this case it would be pink. It does not support the blending theory as it does not get its colour from the dominant plant in this case but from both.

What activation energy was used to start the chemical reaction in the burning marshmallow?
Sonja [21]

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, let's understand some terms

Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.

The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
