Answer:

Same number of neutrons.

Explanation:

What defines an atom as a certain element is the number of neutros in its nucleus. Some atoms have a different number of neutrons, but are still the same element, we call these variants "isotopes".

Two atoms are the same element if they have the same atomic number

Answer: Option A

<u>Explanation:</u>

The atomic number of an element is defined as the number of protons or electrons of an element. This signature of sub atomic particles is distinct for each element. No 2 elements have the same atomic number.

Sometimes the properties of elements are attributed towards arrangement and number of protons and electrons of an element. The elements are arranged according to their atomic number in a periodic table.

Altering protein structure

scoray [572]

The alteration in the protein structures can take place due to many reason. Once, the structure of the protein is altered, it cannot perform its function, as it cannot bind to the site for which it is designated.

Most of the biological processes use proteins in their completion. In case, the protein cannot perform its function, the metabolic process associated with that particular protein may stop and cause severe illness.

The heat can cause the denaturation of the proteins. The proteins are made up of amino acid sequences, the heat can break the peptide bond present between the amino acids present in protein, which can result in alteration of protein.

Hence, the correct answer is option (d). all of them are correct.

Answer:

A secondary pollutant

Explanation:

Pollutants can broadly be classified into two main categories based on their formation or synthesis. 1: Primary pollutants, 2: Secondary pollutants.

1: Primary pollutants

Primary pollutant can be considered as any environmental pollutant that is being directly emitted from a certain source like when we burn coal carbon di oxide is directly emitted into the atmosphere so CO2 is a primary pollutant.

Similarly sulfur di oxide or SO2 is also a primary pollutant that is emitted by the gas emissions of motor vehicles.

2: Secondary pollutants:

On the other hand, secondary pollutant is something that is not directly emitted on earth as an environmental pollutant but some how it is formed due to a reaction of primary pollutant.

Such as mentioned in the question that SO2 when oxidized in air in the presence of enzymes and water, it form H2SO4 or acid rain which directly falls on earth and incurs great amount of damage to not only living organisms but also non-living organisms such as marble buildings.

Therefore, acid rain is secondary pollutant. Please see picture for better understanding.

Hope it help!
