Answer:
The rocks and debris would never accrete into a planet.
Explanation:
Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force, the rocks and debris would not come together to form a clump. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.
Answer:
Explanation:
The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point. ... The other molecules are slightly polar and show the increase in boiling point with molecular weight which is normal. Instead, water boils at +100 C, which is very abnormal.

Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
The major evolutionary episode corresponding most closely in time with the formation of Pangaea was the Permian Extinctions.
The Permian Extinctions happened around 300 million years ago and lasted for around 15 million years. It eliminated over 95 percent of water life and 70 percent of species on land. It was one of the largest extinctions in the history of Earth.

Unlike carbon-based fuels like coal, natural gas, and petroleum, nuclear energy does not release greenhouse gases into the atmosphere. Therefore it does not contribute to global warming.
Explanation:
Nonetheless, nuclear energy is not widely adopted for energy because of its safety concerns. Fission energy is harmful to the environment because of nuclear waste it generates. How this nuclear waste is stored is very important because leakage can lead to contamination of an environs with lethal radioactive elements.
