Answer:

myofibril bulbous end of axon and skeletal muscles fibres.

Explanation:o

It represents the  chemical synapse  of the axon bulbous ends  of the motor neuron ( motor end plate) and the skeletal Muscle fibres.

The influx of calcium ions into the bulbous ends leads to the fusion  and empty of the vesicles containing neurotransmitters into the synaptic cleft.

The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or  PSEP)across the synaptic gap  to the muscles fibers  to initiate  their  contraction or relaxation.

Pollination cycles do not really have any direct effect with the soil. Releasing moisture from leaves does replenish some water needed in the soil that is cycled back through the transport systems of plants but does not hold back soil. Photosynthetic activities only draw up nutrients, minerals, and water from the soil through roots.

Therefore, the often elaborate ROOT SYSTEMS are the answer. This is because the roots hold the plants in the ground (soil) and by this, the plants prevent natural disasters, artificial actions, and/or excess water to wash away soil. The roots help to reinforce the soil and hold it together.

"The growing human population" a. will require an increase in forests and a decrease in agricultural land. b. is best addressed
storchak [24]

Answer:

C. requires the restoration of ecosystems better designed to serve the needs of humans

Explanation:

For a very long time, the survival of plants and animals has been dependent on each other. The plant depended on animals for oxygen and the animals depended on plants for carbon dị oxide.

In recent times, this balance has been altered as humans (higher animals) have started engaging in activities that hurt the ecosystem such as Bush burning, deforestation and other agricultural practices.

In view of this, there is an urgent need for the restoration of ecosystems that suit human needs. This can be done by planting of more trees, reduction in industrial activities that involves emission of harmful gases and wastes into the air, land and water.
