Explanation

For most metals, the temperature coefficient of resistance is positive, meaning that as the temperature increases, the resistance of the metal also increases.

This behavior occurs because, at higher temperatures, the metal atoms vibrate more, leading to more collisions with the electrons flowing through the material, which increases resistance.

Thus, the temperature coefficient of resistance for metals is positive.

Explanation

A chromosome is typically made up of DNA and proteins, particularly histones, which help in the packaging of DNA.

Explanation

 Amylase is secreted in its active form to help break down carbohydrates.

Other enzymes like peptidase and protease are secreted as inactive precursors.

Explanation

The capacitance  𝐶 is defined as the charge  𝑄 stored per unit voltage  𝑉 

Mathematically, it's represented as:

𝐶 =𝑄/𝑉

So, 1 farad (F) is equal to 1 coulomb (C) per volt (V), but the equation doesn't imply that 

1C=1V.

Instead, it means that a capacitor has a capacitance of 1 farad if it can store 1 coulomb of charge when a voltage of 1 volt is applied across it.

Explanation

there are two points in the year when day and night are approximately equal in duration. 

This is called an equinox.

The equinoxes occur around:

• March 20th-21st 
• September 22nd-23rd each year.
  

Explanation

The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix:

generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

The ATP synthesis occurs within the fold in the inner membrane of a mitochondrion.

Explanation

HF has the highest ionic character

because electronegativity difference between H and F is highest.

ionic character follows the order HF >HCl>HBr> HI.

As the electronegativity difference increases ionic character increases.

Explanation

Periscopes allow a submarine, when submerged at a relatively shallow depth, to search visually for nearby targets and threats on the surface of the water and in the air.

When not in use, a submarine's periscope retracts into the hull.
