Explanation:
What do the cell walls of plants and the extracellular matrix of animal cells have in common? They have functional connections with the cytoskeleton inside the cell.
Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer:
your heart rate goes up explaining why the blood is traveling quicker. this causes you to breath faster meaning bring more oxygen to the blood in your lungs faster. your blood pressure also goes up from the increase in heart rate.
The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.
