<span>During nitrification, ammonia is changed back into nitrate.</span>
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.
The answer is c.

The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. However, you are palpating contractions that are strong in intensity with a frequency of every 3 minutes and a duration of 60 seconds. A possible cause for this finding is (select an answer): The connections to the system are not connected.
An IUPC counts the number, length, and force of contractions. During palpations peaks of strong intensity is recored.As in this case IUPC seems to be not connected as its near impossible to get no contractions when palpation are high.
And one unit is the amount of pressure required to raise a mercury column by one millimetre. The intensity of the contraction is assessed from the baseline (when the uterus is relaxed) to the rise of the contraction and is recorded in units. According to studies, after spontaneous labour, 200 units of contractions per 10 minutes are typically sufficient for vaginal birth.

During inhalation, you breathe in and this contracts the diaphragm and moves downwards. This increments the chest cavity space which means the lungs are expanding. The intercostal muscles or the muscles in between the ribs also aids in the enlargement of the chest cavity. Both muscles contract to pull your rib cage upward and outward when you inhale. As your lungs expand, air is sucked through your nose and mouth. It then travels down to the windpipe and into the lungs to the bronchus, bronchioles and eventually in the alveoli where air exchange between carbon dioxide and oxygen happens.
The additional accessory muscles of respiration are typically used only under conditions that are of high metabolic demand or respiratory dysfunction. However, in instances where these muscles become stiff and hard, expansion of the rib cage can be quite restricted. The accessory muscles of respiration include sternocleidomastoid and the scalene muscles namely anterior, middle and posterior scalene. Both aid in elevating the rib cage. However, their involvement seems to depend on the degree of respiratory effort. During quiet breathing, the scalenes are consistently active at certain phases while the sternocleidomastoid is quite.
