Answer:
If the Earth was not tilted on its axis, there would be no seasons. And humanity would suffer.
Explanation:
When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.

Answer:
Muscle contraction function.
Explanation:
The nerve endings possess synaptic acetylcholine vesicles ready to be released. The action potential depolarizes the presynaptic terminal and increases the concentration of axoplasmic calcium; Acetylcholine molecules are thus released, so that the concentration of the neurotransmitter at postsynaptic (nicotinic) receptors is temporarily increased. This is followed by post-synaptic membrane depolarization, muscle membrane action potential with increased rnioplasmic calcium concentration, and finally muscle contraction. Acetylcholine is hydrolyzed by acetylcholinesterase and resynaptic at the presynaptic level by cholinecetyltransferase. The etiopathogenesis of myasthenia gravis is autoimmune and there are antibodies against acetylcholine receptors that circulate in the blood, as well as a decrease in the number of receptors on the motor plates, that is, it is produced by the postsynaptic blockage of the myoneural plaque, that generates fatigue and localized or generalized muscle weakness that is characterized by the worsening of the contractile force of the muscle.
Answer:
True.
Explanation:
White blood cells cannot function properly and their reduced production can lead to fever and frequent infections. This is because the function of white blood cells in fighting germs has been disrupted.
Other signs and symptoms:
- Weak and tired.
- Lack of appetite and weight loss.
- Swelling and bleeding gums.
- Headache.
- Abdominal swelling is caused by enlargement of the liver and lymph.
- Bone pain, can cause weakness.
Joint pain.
- The glands are swollen. If the glands in the neck and chest are swollen, it can cause blood flow to be blocked. This causes the face to swell, difficulty breathing and snoring.
