Answer:
As the cell grows, it faces some issues such as:
• Running out of the nutrients and requirement of growth factors.
• Running out of the space.
• Require appropriate gas exchange.
As compared to the smaller cells, larger cells have more issues in moving the required materials inside and excretory products outside. This is because the ratio of the surface is to volume is turning more and more unbalanced and takes much longer time for the cellular processes to take place.
Explanation:
- 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.

Answer:
<h2>Helicase, topoisomerase ii /gyrase, single strand binding proteins.</h2>
Explanation:
DNA replication is the process in which DNA is replicated with the help of various enzymes and proteins..
Helicase is the enzyme which unwind the DNA strands, After unwinding, topoisomerase removes these twists. Single strand binding proteins stabilize the single strands of DNA during replication.
Answer:
<em><u>You choose a primary care doctor who coordinates most of your care. Preferred Provider Organizations (PPO) usually pay more if you get care within the network. They still pay part of the cost if you go outside the network. Point of Service (POS) plans let you choose between an HMO or a PPO each time you need care.</u></em>
