Rugae are the folds in the stomach that allow it to expand when it is full and increase surface area.
<h3>What are rugae?</h3>
The rugae have the purpose of allowing the stomach and other tissue to stretch as necessary to aid in food digestion. Gastric rugae are ridges of muscle tissue that line the stomach, according to WebMD.
The body's digestion system depends on the gastric rugae. When the stomach is not yet full, the gastric rugae fold into the stomach tissue. The rugae open up when the stomach is full, allowing the stomach to grow. The rugae spread when the stomach empties, returning the stomach to its former size. Only when a tissue or organ is deflated or relaxed are gastric rugae visible in radiological investigations. They expand the stomach's surface area to facilitate

The three structures and physical entities that almost all fish have:
Gills
Fins
Blood
Almost all fish have gill slits because there is no other way they can breathe underwater without having gills.Fins are used to move around the water and blood delivers oxygen and nutrients.

Answer:
1. sports medicine
2. gene therapy
3. Adrenal gland
4. false
5. Hormones
6. To regulate body activities (like growth and immunity) by sending chemical messages
Explanation:
1. Sports medicine is the branch of medicine that is related to physical fitness, so if the question ask for someone who is interested in athletic activity, the correct answer is number 4.
2. Gene therapy is an experimental technique that in order to treat or even to prevent disease genes are used to help with their treatment, so a person who is interested in genetics and its relation with health, the correct answer is number 2.
3. Adrenal gland this is the gland that sintetice Adrenaline also known as epinephrine which is a hormone or also a medicine that plays an important role in the fight or flight response, this hormone is the one in charge of giving us several symptom like tachycardia or dilated pupils in order to survive in dangerous situations, so the correct answer to Sarah's problem is number 1.
4. False the endocrine system serves as a messenger to regulate hormone synthesis and are secreted to the circulatory system.
5. Hormones, as we have answer before hormones are regulated by the endocrine system.
6. To regulate body activities (like growth and immunity) by sending chemical messages hormones play an important part in human development and growth, these chemical messages serve to regulate the synthesis (creation) and secretion (liberation) of the hormones in the specific quantity as the body needs them.
The primary advantage of complete metamorphosis is eliminating competition between the young and old. Larval insects and adult insects occupy very different ecological niches.
Answer: Option A.
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
Explanation:
countercurrent multiplier is a system that utilize energy that create osmotic gradients and enable reabsorption of water thereby increase concentration of urine. The countercurrent multiplier uses electrolyte pumps there by making the nephron loop increase the concentration of salts in the interstitial fluid of the kidney medulla because it allows the nephron to reabsorb alot of water and and increase the concentration of urine for excretion while at the same time using as little energy as possible.
