Answer:

The correct answer is option a. "scales".

Explanation:

The missing information of this question is the following:

"Terry catches a ray-finned fish from the ocean and notices that attached to its flank is an equally long, snakelike organism. The attached organism has no external segmentation, no scales, a round mouth surrounded by a s*cker, and two small eyes. Terry concludes it is a hagfish."

Gymnophiona is a group of amphibians characterized by having dermal scales as integumentary element. These amphibians are tetrapods and their scales are comprised of several layers of unmineralized collagenous fibers. The skeleton of the hagfish is made entirely of cartilage, therefore it is very likely that the tooth-like objects of hagfish's are made of cartilage, just like the scales of the tetrapod.

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.

Where near your home do you think the highest level of photosynthesis is happening?
sveticcg [70]

Answer:

I live in a rural area which is surrounded by mountains and valleys. Near my home there is small forest area where there are hundreds of thick tall forests, algae and many other photosynthetic plants.

The atmosphere of that forest is very clean and refreshing because there is alot of oxygen being produced there due to alot of photosynthesis being done by all the lush green plants there.

Due to photosynthesis, carbon di oxide that is an environmental pollutant is maximum used by the plants and maximum. Oxygen is produced as a result of photosynthesis.

This causes the environment of not only that forest but my whole village very clean and fresh to breath. We are living a healthy life where there is a less prevalence of diseases or infections that are caused by environmental pollutants like Bronchitis, Lungs infection, neural disorders etc.

Therefore, even if there is not such an area near your home, we would suggest you to plant more trees in your backyard that will make the environment of not only your home but your area very fresh and clean.


Hope it help!
