Explanation

For water, the boiling point is 100ºC at a pressure of 1 atm

The boiling point of water decreases at higher altitudes due to Low atmospheric pressure

The boiling point of water increases with increased atmospheric pressure

The boiling point of water decreases with decreased atmospheric pressure

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

It is a highly unstable isotope of hydrogen.

Hydrogen has no neutron.

It contain only one proton and one electron.

But the deuterium contain one neutron and tritium contain two neurons,

these are the isotopes of hydrogen.

Explanation

Explanation

A punctuation mark used to indicate an abrupt turn or break in a sentence is called a dash (specifically, an em dash

Function: To mark a sudden break or interruption in a sentence. 

Appearance: Usually longer than a hyphen. 

Example: "I was going to the store, but then - I remembered I forgot my wallet." 

Explanation

Straw, camphor, alcohol, petrol, diesel etc. catch fire easily to release heat energy and light energy.

So, these are examples of combustible substances.

Explanation

Soil pollution can be caused by acid rain.

It is a type of precipitation that contains high levels of sulfuric and nitric acid.

This can occur when fossil fuels are burned, releasing sulfur dioxide and nitrogen oxides into the atmosphere, which then combine with water and oxygen to form acid rain.

Acid rain can alter the pH of the soil, making it more acidic and potentially harmful to plants and microorganisms.
