Question

Define the following :-

i)Internal respiration
ii) Breathing
iii) Combustion
iv) Rapid combustion

V)Photosynthesis ​

Answer 1

1. Internal respiration refers to two distinct processes. The first is the exchange of gasses between the bloodstream and the tissues. The second is the process of cellular respiration, from which cells utilize oxygen to perform basic metabolic functions.
2. Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to bring in oxygen and flush out carbon dioxide.
3. Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
4. Rapid combustion is a form of combustion in which large amounts of heat and light energy are released.
5. the process by which green plants turn carbon dioxide and water into food using energy from sunlight

Answer 2

Answer:

Answer: •INTERNAL RESPIRATION.

Internal respiration involves gas exchange between the bloodstream and tissues, and cellular respiration. Gas exchange in tissues is a result of tissue surface area, gas partial pressure gradients, and the blood perfusion of those tissues.

•BREATHING.

Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to bring in oxygen and flush out carbon dioxide.

Explanation:

•COMBUSTION.

Combustion, or burning,[1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vapourise, but when it does, a flame is a characteristic indicator of the reaction. While the activation energy must be overcome to initiate combustion (e.g., using a lit match to light a fire), the heat from a flame may provide enough energy to make the reaction self-sustaining.

•RAPID COMBUSTION.

When rapid energy requires external heat energy for a reaction to occur, it is classified as rapid combustion. This reaction will continue to remain live until all of the fuel is burned up. As a byproduct, this form of combustion produces large amounts of heat and light energy at a rapid pace.

•PHOTOSYNTHESIS.

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. ... During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
