The Correct answer is C.
The Island of Hispaniola is the second largest island in the Caribbean, at 29, 237sq miles. Haiti occupies about 1/3 of the Island while the Dominican Republic controls the balance of the land.
Christopher Columbus claimed Hispaniola in 1492, declaring it "the most beautiful island in the world". It later became the launching base for the Spanish conquest of the Caribbean, as well as the American mainland.
The western third of the island became known as Haiti in 1804 and while the remainder became known as the Dominican Republic in 1844.
<h3><u>Answer;</u></h3>
The permeability of the membrane
<h3><u>Explanation</u>;</h3>
- The fluidity and the permeability of cell membrane must be maintained within a certain range for the cell to function properly.
- The permeability of cell membrane depends on a number of factors, among them is the degree of saturation of fatty acids tails making up phospholipids.
- Phospholipid tails can be saturated or unsaturated. Saturated tails have no double bonds and as a result have straight, unkinked tails, while unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
- Interactions between tails are maximized in the case of saturated tails, thus decreasing membrane fluidity and permeability, while unsaturated tails increases membrane fluidity.
Answer:
The answer is D.
Explanation:
The way x-rays are produced is as follows; using a vacuum environment in a tube, the cathode is heated to a degree where it releases electrons, then these electrons collide with the anode releasing energy that create the x-rays.
All of the options are correct. Although the electron most likely won't stop, it will slow down and change direction after the collision. The law of conservation of energy is also applied in this situation, meaning that the kinetic energy of the electron released by the cathode will transfer to the anode to produce the x-rays. Most of the energy after the collision is converted into heat, which is why the metal used as the anode can heat up to 2000 degrees celcius.
I hope this answer helps.
