What is the island of Hispanola named today?
12345 [234]


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.

Lisa had 20 grams of water. She poured out 15 grams. Which of the following physical properties of the water changes? (4 points)
Black_prince [1.1K]

Answer:

Volume

Explanation:

The boiling point and density of water never changes, no matter how much you add

So the answer CAN'T be Boiling point or Density

Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>

So it CAN'T be Electrical Conductivity

It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture

How can you tell what genes are recessive or dominant when looking at actual gene setups?
devlian [24]
By looking at a gene set up or a punnet square,a gene that's dominant would be represented by a capital letter and recessive traits are represented by lowercase letters for example brown eyes are considered a dominant trait which can be represented as BB for homozygous, and Bb for heterozygous. Since blue eyes are recessive they would be bb.

True of False: Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate
Murljashka [212]

Answer: False

Explanation:

Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.

It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.

It depends on the state of activity. It transports more oxygen to the tissue that require it the most.

Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .

Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
