Answer:

Tropism can be defined as a stimulant, with respect to it plant respond to it's external environment. Tropism includes light, water, touch and gravity. The phototropism refers to the movement of plant with respect to the light stimulus. Shoot or stem part of the plant shows positive phototropism because it grows and move in the direction of sunlight, whereas the root shows negative phototropism as it grows against the sunlight.

Yes, plants that live in the desert are expected to show more pronounced phototropism than the forest dwelling plants.This is  because in a desert habitat the tree population is expected to be limited, and the plants are directly exposed to sun. The stem or shoot will be erect. But in forest dwelling plants the plants will be growing in shade of trees, will receive very low amount of sunlight. The shoots may not be erect, instead will be tilted. Hence, in desert plants the phototropism will be more prominent.

AlladinOne [14]

Nitrogen is returned to the atmosphere during the nitrogen cycle in a process referred to as denitrification.

<h3>What is denitrification?</h3>

It is a process whereby nitrogen becomes mineralized from nitrogenous compounds. In other words, it is the reduction of nitrates to produce elemental nitrogen which is returned to the atmosphere.

Denitrification is a microorganisms-driven process. The nitrates are made to pass through a series of reactions with intermediate products before finally leading to the production of elemental nitrogen.

Triggering of the muscle action potential occurs after
vekshin1

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.
