The specific term to characterized the downward
growth of roots in response to earth’s gravity pull is called positive geotropism.
The word geotropism was derived from two words, “geo” which means ground and “tropism”
which describes a plant movement elicited by a gravitational stimulus.
In addition, the root cap makes the roots turn
downward as they grow for they have specialized cells with sensors called
statoliths that settle to the lowermost part of the root cap in response to the
pull of gravity and help the cell multiply more rapidly in a downward direction.

Answer:
Aids energy transfer from a molecule to another
Explanation:
ATP aids energy coupling, combining exergonic reactions to endergonic reactions. In PHOTOSYNTHESIS, ATP is produced in the light reactions for Calvin cycle to produce sugar. In CELLULAR RESPIRATION, sugar undergoes oxidized to produce ATP needed to energize cellular metabolism (ATP is the energy currency of the cell).
ATP is a major source of energy for each and every biological process. In PHOTOSYNTHESIS energy is changed to ATP in the light-dependent phase which is used for synthesis in the dark phase.
ATP is a needed in RESPIRATION. ATP is the energy currency of the cells, sometimes called the “molecular currency” of energy distribution.
<span>Senescence is about growing old. When one is very old, the body naturally deteriorates, and this includes the cells of the body which make up tissues and then organs. The daughter cells not being sustainable is a vital factor in the body gradually being unsustainable.</span>
Answer: Earth's rotation is slowing slightly with time,thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago.
