_____ carry blood back to the heart from the capillaries.
- A.
Arteries
- B.
Veins
- C.
Ventricles
- D.
Red blood cells
Correct Answer
B. VeinsExplanation
Veins carry blood back to the heart from the capillaries. Unlike arteries, which carry oxygenated blood away from the heart, veins transport deoxygenated blood back to the heart. This blood is then pumped to the lungs to be oxygenated before returning to the heart to be distributed to the rest of the body. Veins have thinner walls and valves that prevent the backflow of blood, ensuring that it flows in one direction towards the heart.Rate this question:

What type of blood is a universal donor?
- A.
O
- B.
A
- C.
AB
- D.
B
Correct Answer
A. OExplanation
Blood type O is considered the universal donor because it lacks both A and B antigens on the red blood cells. This means that it can be safely transfused to individuals of any blood type without causing an adverse immune reaction. In contrast, individuals with blood types A, B, or AB have specific antigens on their red blood cells that can trigger an immune response if they receive blood from a donor with a different blood type. Therefore, blood type O is the safest and most compatible option for transfusions in emergency situations when the recipient's blood type is unknown.Rate this question:

Which of the following is a sedimentary rock?
- A.
Granite
- B.
Marble
- C.
Shale
- D.
Slate
Correct Answer
C. ShaleExplanation
Shale is a sedimentary rock because it is formed from the accumulation of fine-grained sediment, such as clay and silt, over a long period of time. These sediments are compacted and cemented together, resulting in the formation of shale. Granite and marble, on the other hand, are both igneous rocks, meaning they are formed from the cooling and solidification of molten rock. Slate is a metamorphic rock, formed from the transformation of pre-existing rock under high pressure and temperature. Therefore, shale is the only option that fits the criteria of being a sedimentary rock.Rate this question:

- B.
The rate of change of velocity.
- C.
The rate at which an object changes position.
- D.
The tendency of an object to continue moving in the same direction.
Correct Answer
D. The tendency of an object to continue moving in the same direction.Explanation
The correct answer is "the tendency of an object to continue moving in the same direction." Momentum refers to the property of an object that causes it to resist changes in its motion. It is a vector quantity that depends on the mass and velocity of the object. The greater the momentum, the harder it is to stop or change the direction of the object's motion. Therefore, momentum can be described as the tendency of an object to maintain its current state of motion, whether it is at rest or moving in a particular direction.Rate this question:

Table salt is considered
- A.
Ionic compound
- B.
Ion
- C.
Covalent compound
Correct Answer
A. Ionic compoundExplanation
Table salt, also known as sodium chloride (NaCl), is considered an ionic compound. This is because it is formed by the transfer of electrons between sodium (Na) and chlorine (Cl) atoms. Sodium donates one electron to chlorine, resulting in the formation of Na+ and Cl- ions. These oppositely charged ions are held together by strong electrostatic forces of attraction, forming a crystal lattice structure. Ionic compounds have high melting and boiling points, are usually soluble in water, and conduct electricity when dissolved or molten, all of which are characteristics exhibited by table salt.Rate this question:
