The correct answer is Includes the Golgi apparatus and the endoplasmic reticulum.
The endomembrane systemrepresents a group of membranes and organelles that works together to modify, package, and transport lipids and proteins. It exists in eukaryotic cells only. The endomembrane system does not include all the organelles, like mitochondria, chloroplasts, or peroxisomes.
Answer:
Climate change leads to a loss of species
Global warming resulting from human emissions of greenhouse gases. The consequences include habitat loss; shifts in climatic conditions and in habitats that surpass migrational capabilities; altered competitive relationships.
Explanation:
Organisms return carbon<span> dioxide to the </span>atmosphere<span> by respiration. It is not just </span>animals<span> that respire. Plants, algae and microorganisms do too. </span>Carbon<span> dioxide is also released into the </span>atmosphere<span> when fossil fuels such as coal and oil, and wood, are burned. hope this helps</span>
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.
<span>The skeletal system in the body provides the shape, supports and protects organs and the soft areas of the body. Its also provides movement, produces blood for the body, and stores minerals that a human needs. So it is not only to provide the body with framework. It is much more.
</span>Hope this helps.
