Explanation

Antibodies are specialized proteins produced by the immune system.

They help identify and neutralize foreign substances like bacteria and viruses.

Explanation

Normal fasting glucose concentration in blood plasma is ~70–100 mg/dL.

It translates to ~0.1% (100 mg/dL = 0.1 g/dL = 0.1%).

Explanation

Since fluorine is more electronegative, its oxidation state is -1.

The molecule OF2 has zero overall charge:

O + 2F = 0

x + 2(-1) = 0

x - 2 = 0

x = +2

Explanation

1 kilowatt hour (kWh) = 1000 watts × 3600 seconds

1 kWh = 1,000 × 3,600 = 3,600,000 joules (J)

Explanation

Centrioles play a crucial role in organizing the spindle fibers during cell division, specifically in mitosis and meiosis.

They help in the formation of the spindle apparatus, ensuring proper chromosome separation.

Explanation

• In the human heart, blood returning from the lungs via the pulmonary veins drains into the left atrium.
• From there, it flows through the mitral valve into the left ventricle, which pumps it out to the rest of the body through the aorta.

Explanation

An ocean current is a continuous, directed movement of seawater.

Ocean current is generated by:

• A number of forces acting upon the water including wind
• The Coriolis effect
• Breaking waves
• Cabbeling
• Temperature and salinity differences.

Additional Information:

Ocean floods:

Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater

Cyclone:

Cyclones are caused by atmospheric disturbances around a low-pressure area distinguished and often destructive air circulation.

Tsunami:

Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.
