Answer:

During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:

transported to the growing parts of the plant for use in respiration

transformed into cellulose, proteins and oils

turned into starch for storage

Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.

Which physiological changes would the nurse anticipate after an amniotomy is performed?
Zina [86]
  • Progressive dilating and obliteration are the physiological changes  the nurse would anticipate after an amniotomy is performed.
  • The fetal head can press more forcefully against the cervix thanks to the artificial rupture of the membranes (amniotomy), which improves dilation and effacement.
  • As labor progresses, vaginal bleeding may become more severe. The fetal heart rate is not immediately impacted by amniotomy.
  • Because contractions typically intensify and become more frequent when the membranes are artificially ruptured, discomfort may worsen.
<h3>What is Amniotomy?</h3>
  • Artificial rupture of membranes (AROM), often known as amniotomy or simply "breaking the water," is the deliberate rupture of the amniotic sac by an obstetrician.
  • This treatment is frequently carried out during labor management and has a variety of indications.
