Answer:
Hydrogen ion
Explanation:
The name of H⁺ is hydrogen ion.

Anthony has been refusing to go to school. Anthony's culture places great emphasis on academic achievement and expects that young people will get no grade lower than an A, and his teacher wonders whether that may be influencing Anthony's school refusal. This illustrates operation of the Macrosystem.
<h3><u>
Explanation:</u></h3>
Urie Bronfenbrenner has developed a theory of ecosystems in which the macrosystem deals with the culture in which an individual survive. There are five differemt environmental systems that has been dealt with this system in which the individual interacts. They are mesosystem,macrosystem, microsystem, chronosystem and exosystem.
When the culture is dealt as a whole and dealing with poverty,ethnicity,status in socioeconomic context and wealth is Macrosystem. They also deal with children their studies and the working nature of their parents. The example given here deals with an individual's emphasis towards academic and the things that influence him. Thus it illustrates the operation of Macrosystem.
1) An action potential is propagated down the lower motor neuron
2) Calcium levels increase in the cytoplasm of the muscle cell
3) Acetylcholine binds its receptor and causes depolarization
4) Vesicles containing glutamate fuse with the nerve terminal
5) Contraction.
Answer:
4,1,3,2,5
Explanation: Glutamate is the neurotransmitter that excites the motor neurons and produces action potential in motor neurons. Then this action potential travels down towards the axonic terminal where it would cause release of acetylcholine. ACh then binds to postsynaptic membrane causing depolarization of sarcolemma. Calcium ions are released into the sarcoplasm resulting in muscle contraction.
Answer:
Inflammatory phase
Explanation:
This is the second phase of wound healing,which is natural body response to injury. it begins with the trransudation (discharge)from the injured blood vessels at the wound site of water, salt and protein fragments;leading to localized swelling.
Thus the inflammatory phase leads to arrest of bleeding at the site
The swelling leads to engorgement of the injured area, which enable the cells for healing and repair( white blood cells WBC) to migrate to the injured site. At this phase ,damaged cells and pathogens are removed from the wound area.
The sequence of reactions of WBC at the wound site, with the growth factors,and enzymes explained the distinct redness, swelling, and pain characterized with the inflammatory phase .thus this phase also prevents infection.
Arent they all 4? if so thats probably your answerr
