Answer:
The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.
Explanation:
<u>Answer</u>: Infundibulum, ampulla, isthmus, uterus.
<u>Explanation</u>:
- The ovary produces the egg and, it releases one unfertilized egg every month.
- The egg then travels through the fallopian tube to the uterus.
- The fallopian tube consists of three parts:
1. <em>Infundibulum</em>- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.
2. <em>Ampulla</em>- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.
3. <em>Isthmus</em>- it is also a ciliated region which controls the transport of both sperm and the embryo.
- Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.
- <em>So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.</em>

Answer:
The given blank can be filled with cytokine storm.
Explanation:
Generally, influenza is self-restricting. Though serious cases can result in pneumonia and other issues, which can be deadly. However, such cases are very common in the elderly and in very young individuals. There are certain strains of the influenza virus, which are more dangerous to young adults in comparison to old or very young.
The strains, which influence young adults are considered to comprise a cytokine storm, that is, a positive feedback loop, which produces in between the production of cytokines and leukocytes. This cytokine storm generates an acute inflammatory reaction, which results in brisk accumulation of fluid in the lungs, resulting in pulmonary failure. The very young or very old are less vulnerable to this influence as their immune systems are less strong.
