The random movement of molecules across a concentration gradient until the difference in concentration between two regions is near zero.
Im thinking it's active transport :) hope it helps.
Actinomycetes will form powdery colonies that stick firmly to the plate and they grow slowly while bacterial colonies are slimy , distinct and will grow faster.
Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems
Answer:The correct order is:
Ion channels - synaptic vesicle - neurotransmitter - end plate potential.
Explanation: A neuromuscular junction is the point where a motor neuron meets with a skeletal muscle fiber which it innervates.
It is the site where a chemical interaction or communication between a motor neuron and a muscle cell occurs. For transmission of impulses to occur between a neuron and a muscle cell, an action potential from the motor neuron travels along the axon of the neuron to the presynaptic terminal of the neuron where it activates voltage gated calcium ion channels which causes the influx of calcium ions into the intracellular space of the neuron. The calcium ions bind to the sensor proteins that are located on the synaptic vesicles and trigger the release of the neurotransmitter into the synaptic cleft. The neurotransmitter moves from the synaptic cleft and binds to its receptors on the postsynaptic membrane of the muscle cell. The binding of the neurotransmitter to its receptors creates end plate potential which causes the skeletal muscle fibers to depolarise.
