In order to see an absorbance peak in an ir spectrum, the molecule must ___________.
Arte-miy333 [17]
<span>The answer is b. have a change in dipole moment

When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>

Which of the following are matched correctly?
kogti [31]

Answer:

<u>1. type IV hypersensitivity: delayed-type hypersensitivity.  </u>

<u>2. type I hypersensitivity: IgE  </u>

<u>3. type II hypersensitivity: IgG  </u>

<u>4. type III hypersensitivity: immune complexes </u>

Explanation:

Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.

What are three ways body systems work together to maintain homeostasis?
mafiozo [28]

Answer:

Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.

For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved. The digestive system also plays a role with variable water absorption. Water can be lost through the integumentary and respiratory systems, but that loss is not directly involved in maintaining body fluids and is usually associated with other homeostatic mechanisms.

Similarly, the cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)
