Answer:
it is highly explosive is the correct answer.
Explanation:
Methane gas must be removed from landfills because it is highly explosive.
Methane gas is highly explosive because it carries chemicals that are present at an explosive level.
Methane gas concentration in landfills is about 50 percent higher than its Upper Explosive Limit and it is expected to cause an explosion hazard.
landfill gas(methane gas) is produced due to decomposing the waste in landfills and landfills gas is dangerous as it results in the greenhouse effect.
2 ways are 1 it can rise into the atmosphere or 2 it can be absorbed into the oceans.
Geothermal energy is heat energy generated and stored in the Earth. ... The adjective geothermal originates from the Greek roots γη (ge), meaning earth, and θερμος (thermos), meaning hot.

Answer: 1,260 cubic mm
(1/6)(7,560) = 7,560/6 = 1,260
multiplying by 1/6 is the same as dividing by 6 (6 and 1/6 are reciprocals)
In a hydra, digestion is completed intracellularly.
Hence option (a) is correct.
Small, freshwater organisms of the phylum Cnidaria and class Hydrozoa are grouped under the genus Hydra. They are indigenous to temperate and tropical climates.
The digestion takes place intracellularly in Hydra.
Because of their ability to regenerate and the fact that they don't appear to age or experience old age, hydra have drawn the attention of biologists.
Like most other cnidarians, hydras have a pretty straightforward digestive system.
They have a two-way digestive system, which differs from mammals in that food and waste enter and exit through the same aperture. A "blind gut" is the name for this configuration.
The center of the hydra's body is occupied by its digestive tract.
