Answer:
2) liquids only
Explanation:
Hydrosphere is a total amount of water on the planet Earth. It includes water on the surface of earth,underground and in the air. A hydrosphere of a planet may be liquid,ice or vapor.
Earth's surface water is available in the form of lakes,rivers and oceans,It also exists in underground as wells,and aquifers.In the air water vapor exists in the form of clouds and fog.
The answer is recessive alleles. Generally, a recessive allele
is the form of a gene that codes for a non-functional protein. When an individual inherits
recessive allele for a gene from both parents, then they are more likely to
suffer a disorder that is attributed to lack of the respective functional protein. Often the heterozygous individual will
not bear the disorder even though they carry
the recessive allele. This is because the
dominant allele is able to mask the
recessive allele by producing a functional
protein.
The answer is the first option.
"They perform well only at very low temperatures."
Despite of advantages of Superconductors such as power and cost efficiency, these conductors have drawbacks. Semiconductors have restricted operation range of operating temperatures. They are required to work at very low temperatures.
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.
