The inner planets are those that orbit closer to the sun: mercury, venus, earth and mars.
Attending to the size this is the increasing order: mercury, mars, venus and earth.
Earth is the largest of the inner plantes.
Answer: Low oxygen content.
Explanation:
There are many dangers to the survival of fish in shallow water that depend on the properties of water.
1. The oxygen content drops during the winter and also in hot weather. Fish cannot survive without enough oxygen in the water.
2. High evaporation rates can drain the pond.
3. Fortunately, water has a high thermal mass, so overheating the water to the boiling point is not an issue.
Of the three reasons given, lack of oxygen is the most critical.
Answer:
carbondioxide last in about 300 to a 1000 years in the atmosphere
This is absolutely false.
There is a wide diversity of life teaming around hydrothermal vents. These communities include primary producer organisms, but instead of obtaining energy from the sun, these bacteria use a process called chemosynthesis to convert minerals and other chemicals in the water into energy. These bacteria support a wide range of other animal species, including giant tube worms, deep sea mussels, serpulid or “feather duster” worms, and vent crabs, the apex predator of the vent community.
Answer:
Apoptosis is a multi-step, multi-pathway cell-death programme that is inherent in every cell of the body. In cancer, the apoptosis cell-division ratio is altered. Cancer treatment by chemotherapy and irradiation kills target cells primarily by inducing apoptosis.
