Explanation
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  fo r   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 ND2-03-2023 ND2-03-2023

Explanation
The greenhouse effect refers to the way certain gases in the Earth's atmosphere. Such as carbon dioxide, methane, and water vapor , trap heat from the sun, keeping the planet warm enough to support life.

Explanation
Thermochemistry is the study of chemical reactions and the energy changes that involve heat. *** RY24012023

Explanation
The burning of substances in air or oxygen on heating, with the release of a large amount of heat energy and light energy, is called combustion while In conduction , heat transfer occurs between objects by direct contact. In convection , the heat transfer takes within the fluid Condensation is the process by which water vapor in the air is changed into liquid water; it's the opposite of evaporation ** ND22-1-2023 *** RY24012023

Explanation
Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens. The concave lens are known as diverging lenses, as the rays diverge after falling on the concave lens. *** RY24012023

Explanation
The Milky Way is the galaxy that contains our solar system It consists of  100–400 billion   stars The Milky Way is a huge collection of:  stars dust gas It is visible as a hazy band of white light Additional Information The nearest galaxy to our Milky Way is  Andromeda Largest galaxy in the Universe is  a Spiral galaxy

Explanation
Retina : The retina is the light-sensitive tissue at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve. Vitreous gel : The vitreous gel is a transparent, colorless mass that fills the rear two-thirds of the eyeball, between the lens and the retina. *** RY24012023

Explanation
Inclined planes are used to move heavy loads over vertical obstacles. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.  ND20-1-2023

Explanation
The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth. Thus, the gravitational attraction on the Moon is much less than it is here on Earth , and a person weighs less on the Moon. ND20-1-2023

Explanation
The physical weight of our body is determined by the pull of gravity on it ND20-1-2023
