Answer:
The precise definition of pH is "the negative common logarithm of the activity of hydrogen ion in solution". For practical purposes, the activity is approximated as concentration in moles/L: pH = - log 10 ([H+]) .
Explanation:
First of all the element of nature is lost and also some life ((A LOT OF WHICH IS TREE LIFE)). I hope this helps :)
Answer:
a. Lower
b. Stimulates
In negative geotropism of shoots, auxin is redistributed to the lower side of the cell, where the amyloplasts have accumulated, where it stimulates cell elongation.
Explanation:
Geotropism can be defined as the direction the various parts of a plant grows toward due to the stimulus which in this case is the force of gravity. Geotropism in plants can be negative or positive.
Negative geotropism occurs when the shoots of a plant grows upwards against the force of gravity.
<span>The
conceptual model provides a concept of how the components of an atom
are arranged, implying a similarity of the forces acting between those
components.
It is important to note that the conceptual model is not necessarily
correct or accurate. It simply provides a model which forms the basis
for the discussion of the concepts involved.
Science is all about the discussion -- with the expressed aim of
improving the conceptual model to the point that it is self-consistent
and consistent with the existing body of accepted knowledge. [The
hardest part is knowing when and how to question the body of accepted
knowledge.] </span>
