Answer:

The correct option is: an increase in body temperature due to high fever

Explanation:

Denaturation of protein is a process by which the protein unfolds i.e. loses it's quaternary, tertiary, and the secondary structure when exposed to high temperature (above 41°C), change in pH or chemical denaturants. Denaturation of proteins leads to loss of activity.

The enzymes pancreatic proteases breaks down proteins by hydrolysis, thus leading to the denaturation of protein.

Since, generally fever does not increase the body temperature above 41°C. Therefore, it doesn't lead to denaturation of protein.

Strontium nitrate, Sr(NO3)2, is used in fireworks to produce brilliant red colors, Suppose we need to prepare 366.6 ml. of 0.115

natulia [17]

Answer:

$\boxed{\text{8.91 g}}$

Explanation:

1. Calculate the moles of Sr(NO₃)₂

$n = \text{366 mL} \times \dfrac{\text{0.115 mmol}}{\text{1 mL}}= \text{42.09 mmol}$

2. Calculate the mass of SrNO₃)₂

$m = \text{42.09 mmol} \times \dfrac{\text{211.63 mg}}{\text{1 mol}}= \text{8910 mg} = \text{8.91 g}\\\text{The mass of strontium nitrate required is }\boxed{\textbf{8.91 g}}$

Answer : The correct option is, electron.

Explanation :

As we know that,

An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.

The electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

According to the question, the electron subatomic particle found revolving around the nucleus.

Hence, the correct option is electron.
