Answer:
The correct answer is arteries.
Explanation:
The ventricles refer to the lower two chambers of the heart. The prime function of the ventricles is to pump blood to the rest parts of the body. Arteries refer to the vessels, which will be the first one to come in contact with the blood from the ventricles.
Arteries are the blood vessels, which mediate blood away from the heart to the other parts of the body like tissues and lungs. The arteries are strong, thick, and exhibit elastic walls. The distinct types of arteries comprise elastic arteries, muscular arteries, and arterioles.
Open system: has the transfer and exchange of matter and energy in the system's surroundings.
Closed system: has a limit to how much matter is exchanged.
All of Earth's systems are considered open systems, but as a whole, they are closed.
Answer;
ADP gains a phosphate group to create ATP, which stores energy for making sugars.
Explanation;
-ATP is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation.
-ATP is the main carrier of energy that is used for all cellular activities. When ATP is hydrolyzed and converted to adenosine diphosphate (ADP), energy is released. The removal of one phosphate group releases 7.3 kilocalories per mole, or 30.6 kilojoules per mole, under standard conditions.
Answer:
b. The hydrophobic effect is driven largely by the entropy of the non-polar substance.
Explanation:
The hydrophobic effect is the tendency of nonpolar substances to aggregate when placed in a watery medium. Water has a tendency to form a maximum number of hydrogen bonds with other water molecules or polar substances. When the nonpolar substances are present in water, the water molecule is not able to form the optimum number of hydrogen bonds.
The nonpolar substance orient themselves around the water molecule to allow the formation of hydrogen bonds. This orientation is energetically unfavorable as water molecules are present in a more organized pattern and have lesser entropy that the bulk water. This results in a hydrophobic effect wherein the nonpolar substances exclude water to increase the entropy of water.
Answer:
A. They have identical DNA in all of their cells.
Explanation:
Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.
