who composed cell theory
what is reflection, respiration, breathing, excretion,waste management, reproduction​

Answer 1

Answer:

Matthias Schleiden

The three scientists that contributed to the development of cell theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. A component of the cell theory is that all living things are composed of one or more cells. A component of the cell theory is that the cell is the basic unit of life.

reflection

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

respiration

the act of respiring; inhalation and exhalation of air; breathing. Biology. the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.

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 by bringing in oxygen and flushing out carbon dioxide

excretion

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life

waste management

Waste management includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process

reproduction

Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual.

Answer 2

Answer:

1. Reflection:an image that you see in a mirror, in water or on a shiny surface
2. Respiration:a process by which living things produce energy from food. Respiration usually needs oxygen; breathing
3. Excretion:the process of removing waste materials from the body
4. Waste management:Waste management includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process.
5. Reproduction:the process of producing babies or young ones;the production of copies of something
