Answer:
The diversity of life has generally been divided into a few — four to six — fundamental 'kingdoms'. The most influential system, the 'Whittaker' five kingdom structure, recognises Monera (prokaryotes) and four eukaryotic kingdoms: Animalia (Metazoa), Plantae, Fungi and Protista .

Answer:
option C
Explanation:
Plants may serve as starting point when observing the carbon cycle. they undergo a process called photosynthesis that enables them to absorb and utilize carbon dioxide from the atmosphere and combine it with water. in the presence of the energy of the Sun absorbed by chlorophyll in plants, they are able to synthesize sugars and oxygen molecules. They play a huge in keeping the air clean with the carbon becoming a part of the plant. Plants and other organisms that die and become buried may be converted into fossil fuels made of carbon like coal and oil over millions of years. when these are then burnt by humans, most carbon then return to the atmosphere as carbondioxide.
Explanation:
-acid-base homeostasis
The cells within the brain or CNS ensure that more oxygen is taken into the lungs at a faster rate while carbon dioxide is removed; this aids in gaseous exchange and maintaining the pH of the blood- oxygen concentrations are kept high within the blood stream as blood circulates through the body.
Blood pH levels are typically within 7.35 --7.45. it is regulated by coordinated activity controlled by the brain, and carried out by the kidneys and lungs; along with red blood cells.
Further Explanation:
During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.
Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by feedback loops (positive and negative), where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
The peripheral nervous system is divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.
