Answer:
The correct answer would be Carbon dioxide comes from the air and is broken down in the Calvin cycle.
Photosynthesis can be divided into two steps namely light-dependent and light-independent reactions.
In light-dependent reaction, light energy of the sun is converted into chemical energy (ATP and NADPH). Photolysis of water takes place in this process which releases oxygen as the byproduct.
In light-independent reaction (also called as Calvin cycle), carbon-dioxide obtained from air is broken down and rearrange to fix carbon in the form of glucose. The reaction is catalyzed by the enzyme RuBisCO.

What is heat? Heat is the energy needed to change the temperature of 1 g of a substance by 1°C. Heat is the average kinetic energy of the particles of a substance. Heat is the total energy of a substance due to the movement of its particles. Heat is the energy that flows between two substances of different temperatures.
Heat is the energy that flows between two substances of different temperatures. Thus, Option D is correct.
What do you mean by heat energy?Heat is a measure of energy. It flows from a warmer object to a cooler object.
The mechanism of heat generation include, with the increase in body temperature followed by the increase in generation of atomic or molecular vibrations.
Thus, these vibrations are then transferred from one part of the body to another, the form of energy where the molecules vibrate and stored is termed as heat.
Due to law of thermodynamics, transfer of heat takes place from higher temperature region to lower.
Heat energy can be use for various activities like cooking, ironing, transportation etc.
The uneven heating of different regions can cause the occurrence of the wind, rain, change of seasons. Thus, Option D is correct.

The prefix photo- means "light". The root word synthesis means "putting together". How could knowledge of these word parts help you define the word photosynthesis?
Photosynthesis can be understood as 'putting together with light', as it is a process where green plants and certain organisms synthesize foods using sunlight.
Explanation:Understanding the meanings of word parts can greatly assist in knowing the definition of a whole word. In the context of the term photosynthesis, the prefix 'photo-' means 'light' and the root word 'synthesis' means 'putting together'. Therefore, if we combined these meanings, we could interpret photosynthesis as 'putting together with light'. In biological terms, photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. Essentially, they are 'putting together' nutrients using 'light'.

When two objects collide, the momentum of the system remains constant. This is a statement of
Question 16 options:
Newton's third law
the conservation of momentum
impulse
a change in momentum
The statement that momentum remains constant in a collision with no external forces refers to the principle of the conservation of momentum, a fundamental concept in classical mechanics.
Explanation:When two objects collide and there are no external forces acting on them, the statement that the momentum of the system remains constant is a principle known as the conservation of momentum. This principle is a cornerstone of classical mechanics and indicates that the total momentum of a closed system will not change as a result of interactions within the system. An example of this can be seen when two cars collide; car one may slow down, losing momentum, while car two speeds up, gaining momentum. Despite these individual changes, the total momentum of the car system remains constant, assuming all forces between them are internal to the system.
