Answer:
Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.
Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. In those cases, there is an advantage of having friction.
Quite often uses of frction can be seen from how things would be without friction. Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
Explanation:
8. (F) Facilitated diffusion: For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins.
9. (S) Simple diffusion: While water molecules are polar, they are also very small. One fact not mentioned in the video is that some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size.
10. (S) Simple diffusion: Charged ions are traveling through a cell membrane with the concentration gradient.
11. (A) Active transport: Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells.
12.(F) Facilitated diffusion: At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell.
The above choices are made based on the basic definitions of active transport, facilitated diffusion and simple diffusion.
Active transport: The movement of the ions or molecules to a region having higher concentration across the membrane requiring the help of energy or enzymes is active transport.
Facilitated diffusion: This type of transport involves passive movement of the molecules or is a type of passive transport where the movement of the molecules takes place from higher to lower concentration region occurs with the aid of a carrier molecule such as a transport or carrier protein.
Simple diffusion: This process involves movement of ions or molecules from high concentration region to low concentration region through a semipermeable membrane.
C. The law of segregation. Hope this helps.
- A hiatal hernia is when a portion of the stomach protrudes through the diaphragm's esophageal gap.
- Congenital or acquired, intermittent herniation and clinical symptoms are both common with hiatal hernia.
<h3>What is an esophageal hernia?</h3>
- When the stomach, the bottom portion of the esophagus, or other organs rise up into the chest, it is known as a paraesophageal hernia.
- Organs move from the chest into the belly through the diaphragm's (the muscle dividing the chest and abdomen) hiatus.
<h3>What is the hiatal hernia's pathophysiology?</h3>
- The most frequent hiatus hernia is sliding: Above the diaphragm are the gastroesophageal junction and a section of the stomach.
- Hiatus hernia of the paraesophagus: The gastroesophageal junction is where it should be, but the diaphragmatic hiatus causes a piece of the stomach to be next to the esophagus.
<h3>What results in a stomach hiatal hernia?</h3>
- being born with a larger than typical hiatal aperture, damage to the locality.
- alterations to your diaphragm with age.
- a buildup of pressure in your abdomen, such as from pregnancy, obesity, coughing, lifting heavy objects, or straining when using the restroom
<h3>What issues are brought on by a hiatus hernia?</h3>
- Hiatus hernia problems are uncommon, but long-term oesophageal damage from stomach acid leakage can result in ulcers, scarring, and alterations to the oesophageal cells, raising your chance of oesophageal cancer.

<span>Some of the factors that lead to contracting HBV are not preventable by choice. It is a virus that is spread by sexual activity, sharing needles, from mother to child, and from improper needle handling by medical professionals. The latter two (contracting at birth or from malpractice) don't allow any choice for the person who receives the virus, and there is nothing you could do to prevent it from happening.</span>
