Scientists sometimes make discoveries that lead to a need for new laws. the big idea of biology do these situations illustrate in biological systems.
A biological system is a group of organs working together to perform a not unusual characteristic. as an example, the muscular gadget is worried about movement, the skeletal gadget gives safety and assistance, and the circulatory system offers nutrients and waste to and from the cells of the body.
Organic structures are the breathing system, digestive system, and circulatory gadget. The human frame includes the subsequent structures: respiration machine – liable for one of the crucial features in any living organism, respiratory, and gas trade.
A biological system is a complex network that connects numerous biologically relevant entities. the organic company spans numerous scales and is decided based on totally special systems.

Answer:
Denaturation occurs.
Explanation:
When a chemical relaxer and heat applied to a curly hair, the protein present inside your hair get denature. Due to this denaturation of protein in the hair, the hair are soft and flexible which can be converted into any direction and different styles can be done. If chemical perm or relaxer is applied to straight hairs, it also denature the protein and make the hair curly.
Answer:
The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.
Explanation:
Answer:
The correct answers are: Synaptic Active Zones, Exocytosis.
Explanation:
- An impulse after travelling along the dendrites, cell body and axon of a neuron reaches the axon endings in the form of an action potential (signal transmitted by the activation of voltage gated sodium and potassium channels present on the plasma membrane of the neurons).
- At the axon ending or the pre-synaptic region, the action potential triggers the opening of the voltage dependent calcium channels, that promotes the influx of calcium ions into the pre-synaptic region of the neuron.
- This process triggers the fusion of the neuro-transmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neuron.
- As a result of fusion the neurotransmitter is released into the synaptic cleft.
- At the pre-synaptic region of the neuron, there is a huge concentration of neuro-transmitter carrying vesicles which remain adhered to proteins called CAZ (cytomatrix at the active zone) proteins. These proteins help the neurotransmitter carrying vesicles to remain tethered or docked to the pre-synaptic membrane in the axon terminal of the neuron. They together form the Synaptic Active Zone.
- In response to calcium ion influx these proteins help the neurotransmitter carrying vesicles to fuse with the plasma membrane in the pre-synaptic region of the neural axon and release the neurotransmitter into the synaptic cleft.
- The process of fusion of the neurotransmitter carrying vesicles with the plasma membrane in the pre-synaptic region of the neural axon followed by the release of the neurotransmitter into the synaptic cleft is known as Exocytosis.
