Answer:
The heart valves prevent the backward flow of blood.
The aortic valve is located between the left ventricle and the aorta.
After the left ventricle contracts, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle.
Each valve actually has three flaps, except the mitral valve, which has two flaps.

Why is it important to measure liquid vs dry ingredients differently?
Answer:
because they have different weights and concistencies
Explanation:
answer/ explanation:
the difference is that each measuring container/cup/scoop is designed to do a job of measuring dry or water ingredients rather then both of them.
lets use backing as an example!
it is much easier to have accurate measurements when you do plan on baking. plus it is very important to have the accurate ingredients and measuring or your dish may not come out the way you want it to
when you are following a recipe, it is much easier to pour a liquid in a clear measurements cup to see the correct measurement line to make sure that you aren't going over or under rather then a tiny scoop.
while it is harder to pour dry ingredients into that same big clear cup. which is why we use scoops for dry ingredients!

When subtracting two fractions you subtract the numerators and the denominators true or false
Answer:
Ture
Explanation:
Answer:
When subtracting fractions you only subtract the numerators. So False
Explanation:
In order to subtract fractions you have to find a common denominator between the fractions you are subtracting.
Example:
3/4 - 1/2 I have to find the common denominator which is 4.
So 3/4 satys the same but 1/2 turns into 2/4
So you problem would now look like this:
3/4 - 2/4 = 1/4
Hope I helped:)

It is usually caused as a result of an exposure to extremely hot environments for an extended period of time. Some of the symptoms or signs of heat exhaustion are thirstiness, paleness, weakness, dark-colored urine, profuse sweating, nausea, headache, dizziness, fainting, rapid pulse, etc.

What occurs when chyme moves too slowly through the large intestines, leading to the
reabsorption of too much water?
Chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid. Once food is in the small intestine, it stimulates the pancreas to release fluid containing a high concentration of bicarbonate. This fluid neutralizes the highly acidic gastric juice, which would otherwise damage the membrane lining of the intestine, resulting in a duodenal ulcer. Other secretions from the pancreas, gallbladder, liver, and glands in the intestinal wall add to the total volume of chyme.
Muscular contractions of the stomach walls help to mix food and digestive substances together in forming chyme. As particles of food become small enough, they are passed at regular intervals into the small intestine. Once in the intestine, more enzymes are added and mixing continues. When food particles are sufficiently reduced in size and composition, they are absorbed by the intestinal wall and transported to the bloodstream. Some food material is passed from the small intestine to the large intestine, or colon. In the colon, chyme is acted upon by bacteria that break down the proteins, starches, and some plant fibres not totally digested by the other organs. In both the small and the large intestine, water is normally absorbed so the chyme gradually gets thicker. As chyme passes through the stomach and intestine, it picks up cellular debris and other types of waste products. When all of the nutrients have been absorbed from chyme, the remaining waste material passes to the end of the large intestine, the sigmoid colon and rectum, to be stored as fecal matter until it is ready to be excreted from the body.
