Answer:
B. Ataxia
Explanation:
Ataxia is a medical condition that is characterized by impaired balance or coordination as a result of a damage to the cerebellum or nerves and muscles that control coordination and voluntary movements. Alcohol intoxication, certain medications, stroke, cerebral palsy, degeneration of the brain, are some of the causes of ataxia. Individuals suffering from ataxia might exhibit signs like unsteady gait, difficulty with speech, lack of eye coordination, etc.
Answer:
Earth and space science explores the interconnections between the land, ocean, atmosphere, and life of our planet. These include the cycles of water, carbon, rock, and other materials that continuously shape, influence, and sustain Earth and its inhabitants
Explanation:
Answer:
4,3,1,5,2
4. Vesicles full of acetylcholine are stored at the axon terminal.
3. Action potential arrives at the neuromuscular junction.
1. Action potential is propagated in the sarcolemma.
5. Acetylcholine is released into the synaptic cleft.
2. Acetylcholine binds to ligand gated sodium channels.
Explanation:
Nerve impulse is generated from somatic motor neurons and reaches neuromuscular junction. The nerve impulse specifically reaches a region named 'synaptic end bulbs' at axon terminal. These synaptic end bulbs are in turn connected to the motor end plate region of a sarcolemma.
As soon as the nerve impulse reaches neuromuscular junction, it triggers the opening of voltage gated ion channels which in turn facilitate the influx of Ca²⁺ from the extracellular fluid to the inside of neuron where synaptic vesicles containing neurotransmitter acetylcholine are already stored.
The Ca²⁺ causes the exocytosis of synaptic vesicles which fuse with the plasma membrane of motor neuron as a result of which acetylcholine is released in the synaptic cleft.
The acetylcholine further binds with the acetylcholine receptor which is present at the motor end plate of a skeletal muscle fibre. These receptors are ligand gated ion channels.
Binding of acetylcholine with its receptor causes the ion channels to open and cations like Na⁺ enter the muscle fibre so as to make the electric potential inside the muscle positive.
Answer: Aquifers are structures used to transport water from city to city
Explanation: Aqui or Aqua means water... the word fer looks life transfer or reminds me of the word transfer so the word Aquifer means to transfer water
