Suppose that while the reverse osmosis system is running tank B becomes contaminated with salt water such that it ends up with a higher salt concentration than tank A. What would happen if the reverse osmosis system was turned off?A) There would be a net flow of water from tank A to tank B.B) There would be a net flow of water from tank B to tank A.C) Water would flow in equal amounts in both directions.

Answer 1
Answer:

Answer:

The correct answer is: A) There would be a net flow of water from tank A to tank B.

Explanation:

  • Osmosis can be defined as the process by which molecules of a substance (water) tend to move from a region where its concentration is high to a region where is concentration is low across a semi-permeable membrane.
  • The force which causes this movement is called the Osmotic Pressure.
  • Reverse Osmosis can be defined as the process by which molecules of a substance (water) move from a region where its concentration is low to a region where its concentration is high, due to the application of a hydrostatic pressure which is more than the osmotic pressure.
  • In the given example, water is is being separated from the salt dissolved in it by the process of Reverse Osmosis.
  • This results in the accumulation of salt in Tank B and accumulation of pure water in Tank A. Reverse osmosis promotes the movement of water from Tank B (where the water concentration is low but salt concentration is high) to Tank A (where the water concentration is high but salt concentration is low) due to the hydrostatic pressure.
  • Stopping Reverse Osmosis will cause normal Osmosis to occur.
  • Hence, the water will move from tank A (where its concentration is high) to tank B (where its concentration is low) until water concentration in both the tanks become equal.

A technique in which the muscles are stretched by an outside force is called passive stretching.

Answer;

Passive stretching

A technique in which the muscles are stretched by an outside force is called  passive stretching.

Explanation;

There are several type of stretching which includes;

  • Active stretching is a technique in which muscles are stretched by the contraction of the opposing muscles.
  • Ballistic Stretching is a technique in which muscles are stretched by the force generated as a body part is repeatedly bounced, or swung.
  • Dynamic Stretching is a technique in which muscles are stretched by moving joints slowly and fluidly through their range of motion in a controlled manner; also called functional stretching.
  • Static stretching is a technique in which a muscle is slowly and gently stretched and then held in the stretched position.

Which of the following is a TRUE statement regarding the skeletal system? There are 28 vertebrae that cover the spinal cord. There are 14 pairs of rib bones that make up the thorax. There are 10 major facial bones. There are 3 components to the sternum bone.

Answers

Out of the statements presented regarding the skeletal system, the last one would be the only true statement which says that there are 3 components to the sternum bone.

For the number of vertebrae that cover the spinal cord, there are around 31 segments that have it. For the pairs of ribs, there are 12 pairs of it. There are also 14 major facial bones. As for the components of the sternum bone, there are 3 components which are as follows: the manubrium, the body, and the xiphoid process.

HELP PLEASE“How do the cardiovascular and digestive systems work together?”
Which organs are vital in the cooperation between the two systems? HOW do they work together?
Think about the organelle that primarily uses Oxygen. What does it use oxygen for? How is this related to the digestive system? HINT: Look up cellular respiration. Where do the reactants for cellular respiration come from (the left side of the cellular respiration equation)?

Answers

Answer:

I can’t answer all of them, but I’ll answer the oxygen ones.

The mitochondria uses oxygen. In mitochondria, this process uses oxygen as a waste product. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

I hope this helps, even though I only answered 3 of your questions!!
