Answer: The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. They were used to demonstrate the power of atmospheric pressure. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of horses.
Explanation:
Answer: It converts carbon to oxygen
Explanation: During photosynthesis, plants create glucose and oxygen molecules
Answer: 26 chromosomes.
The diploid number is the number of chromosomes required for two
sets of copies of the organism’s genome ( this is the number of chromosomes in the cells except gametic cells). The organism's genome is represented as n, and the diploid number,as 2n (2 x 13= 26).
Answer:
organ level
Explanation: because multiple types of tissues are working together.
The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.
Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.
Explanation:
The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.
In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.
The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.
There will be a transfer of these inorganic nutrients to the trophic level in food chain.
