Answer:There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).
Explanation:
Circumstance <span>that cause an increase in Blood Pressure:
</span>
- increasing levels of aldosterone ((influences the reabsorption of sodium and excretion of potassium in the
kidneys. This will indirectly influence the blood pressure since the
volume of blood will change)
<span>- vasoconstriction ( blood vessels increase their contraction, which equals to more pressure)
</span>
-increased release of renin (Converts angiotensinogen, secreted in the liver, into angiotensin I).
- increased activity of Angiotensin-converting enzyme ( this enzyme converts angiotensin I into angiotensin II increasing vasoconstriction).
Circumstances that cause<span> a Decrease in Blood Pressure:
</span>
<span>- decreased sodium reabsorption ( by decreasing sodium, the amount of water will also decrease or , in other words,will be excreted. Less water, will decrease volume of blood and that means less blood pressure)
</span>
- vasodilation (The smooth muscle in the <span>blood vessels decrease their contraction, which equals to less pressure)
</span>
- declining levels of ADH(ADH <span>is produced in the hypothalamus and stimulates
vasoconstriction plus it promotes water reabsorption in the kidneys. To reduce blood pressure, is important to have ADH levels reduced)</span>
Answer:
Verify if the aunt has the right to consent for the child, then proceed.
Explanation:
It is very important to know if the aunt has the consent of the child's parents to make a medical decision. This is because the child is a minor and cannot make a decision about whether or not to accept the procedure. Then a responsible adult of the child must sign documents that make clear the knowledge of the implications of the procedure.
<span>The hormone Oxytocin is released during positive physical contact between humans. It creates a stress lowering reaction and increases bonding between the parties. This creates attachment, and the effect is present in all types of human relationships, ranging from the bond between mother and child to romantic couples.</span>
