3750 of the dominant allele. 1250 of the recessive. 50% hybrid, 25% pure dominant, and another 25% recessive.
Answer:
Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.
I’m not 100% sure if this is a scientific theory but I’m going with the big bang theory. The big bang theory is a scientist best guess on how the world came to be. A 2013 map of the background radiation left over from the Big Bang, taken by the ESA's Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe.
The energy that can be renewed again and again is known as renewable source of energy. Example : water, sunlight, wind et cetera.
The energy cannot be created again,once destroyed is known as non renewable source of energy.
The energy obtained from coal is non-renewable.
Energy obtained from burning plant waste is renewable
Energy obtained from water spring inside the earth is renewable.
Energy obtained from natural gas is non renewable.
