Fish and amphibians commonly conduct fertilization.

Answers

Answer 1
Answer: Fish and amphibians commonly conduct fertilization externally. External fertilization occurs when the female releases the eggs into the environment and then the male releases sperm on top of the eggs.The eggs are then fertilized. Internal fertilization occurs when fertilization happens inside the female's body. After fertilization, the female either bears live young or lays eggs which hatch. Both of these processes take place after a period of incubation either internally or externally. Eggs which are externally fertilized do not have a hard external protective covering or shell.

Answer:

B

Explanation:

Obesity is cause by accumulating fat, Heart disease is not hereditary, and muscular dystrophy an be caused by stress according to the BBC
The answer is D.
Obesity can be caused by low metabolism, bad diet, and lack of exercise. There are two kinds of diabetes. It doesn’t specify which type though. Type 1 diabetes is hereditary, but type two can be caused by bad diet and lack of exercise. Heart disease can be caused by many things, from stress to (once again) not taking care of your body.

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.

Answers

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.
