Answer: downward or lower side : triggers and stimulates

Explanation: In negative geotropism, plant stem tends to move away from gravity. The stem bends upwards against the downward gravitational pull.

Plants stems have hormones called auxins which settle at the bottom/lower part of the cells and allow plants to sense gravity. The auxin also triggers elongation and growth in plant cells.

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.

In communities where zebra mussels have invaded we observed that the population of invertebrates, zooplankton, and phytoplankton they will decrease when in open water. The population of bottom-dwelling invertebrates which are in the littoral zone will increase.
Hypothesis shows the zebra mussels will affect the fish negatively that feed on plankton in the open water but affect positively the fish which feed on invertebrates which are in the littoral zones.
The predictions by following the invasion of zebra muscles show that the number and growth rate of fish species in open water will decrease in population whereas the number and growth rate of fish species in the littoral zone will increase in population.

The OH on the lower right of lysine and the H on the lower left of valine combine to form a molecule of water (H2O) and detach in a process known as a dehydration reaction when the two amino acids bond. The C on the right side of lysine then single bonds with the N on the left side of valine. This bond is termed a peptide bond. All the other bonds remain unchanged.
