So, there's five steps to the scientific method: Identifying the problem, forming a hypothesis, doing research and collecting background data, conducting the experiment, and finally coming to a conclusion. Arya already completed step one and two, because she sees a problem (the dry soil), and then comes up with a hypothesis, which is the water content in the soil in her yard is 2/3 lower due to the slope of her yard. Next, she's going to have to go and collect her data! This may include taking soil samples from her own yard and her other neighbors yard, and then measuring the slope of their yards ect. Then, she's going to take this information and put it into the experiment stage, and then she will come to her final conclusion!
The alveolus (singular form) or alveoli (plural
form) are tiny sacs of organs that are attached to the ends of the alveolar
duct. These tiny sacs of air are clumped together that form interconnected
caves, working together as a unit. They are found inside the lungs and they
make the exchange of air easy and possible. Alveoli units are responsible for
putting oxygen into the air that we breathe in. Blood that passes through the
heart and into the lungs are converted into oxygen which will be then
transported by the blood all over the body systems.
<span>
The walls of the alveoli are extremely thin to
enable the quick exchange of gases Aside from this, the linings of alveoli
units are fluid in nature enabling gases to dissolve. </span>
Answer:
Myelin sheath
Explanation:
Myelin sheath cover the axon of neurons and act as insulator for the faster transmission of signals.
Each axon is covered by multiple myelin sheaths and the gap between myelin sheath are known as Nodes of Ranvier.
In CNS myelin sheath is composed of glial cell called as oligodendrocytes and in PNS the myelin sheath is composed of Sachwann cells (glial cells).
