Explanation

White phosphorus is highly toxic and reactive.

It can ignite spontaneously in air and is harmful to the liver and kidneys.

It’s the most dangerous form of phosphorus.

Explanation

The mass of a nucleus is always less than the sum of the masses of its constituent nucleons.

This difference in mass is known as the "mass defect".

When nucleons come together to form a nucleus, they release energy in the form of binding energy.

According to Einstein's famous equation E=mc², this energy released corresponds to a decrease in mass. 

Explanation

Coal can be converted to petroleum through the Fischer-Tropsch process. 

The Fischer-Tropsch process is a series of chemical reactions

That converts carbon monoxide and hydrogen (syngas) into liquid hydrocarbons, which can be used as a substitute for petroleum. 

Explanation

The organelle responsible for the breakdown of fatty acids and detoxification of alcohol in the liver is Peroxisome. 

Peroxisomes are small organelles that contain enzymes capable of breaking down fatty acids and detoxifying harmful substances like alcohol. 

Explanation

If bleeding starts from a wound, you should apply direct pressure to the wound using a clean cloth or gauze pad until the bleeding stops, and then use a roller bandage to hold the dressing in place and maintain pressure on the wound

Explanation

If you don't wash your body regularly, you can experience unpleasant body odor,

• increased risk of skin infections,
• clogged pores,
• acne flare-ups,
• irritation,
• a build-up of dirt, sweat, and dead skin cells

It can also lead to a condition called "dermatitis neglecta" in extreme cases,

Explanation

The P wave and PR segment is an integral part of an electrocardiogram (ECG).

It represents the electrical depolarization of the atria of the heart.

Typically, a small positive deflection from the isoelectric baseline occurs just before the QRS complex.

Explanation

Fission is much easier to achieve than fusion although fission produces long-term radioactive by-products that are not created with fusion.

the suns are fusion reactors. 

Explanation

They can be reshaped – False.

While cartilage is flexible, it does not permanently change shape without surgical intervention or long-term external force (like in orthodontics or ear reshaping).

It’s not inherently reshaping like soft tissues.

Explanation

1-Butyne is an alkyne, and the hydrogen atom attached to the triple-bonded carbon is relatively acidic due to the high s-character of the carbon involved in the triple bond.

This allows it to donate a proton (H+) in an acid-base reaction.
