Protons and neutrons are energy particles found in the nucleus of atoms.
Explanation:
The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.
The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.

A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
The answer is; hydrothermal, geothermal, and wind
Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.
The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels. Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.
Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .
The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.
Answer:
What is the largest sediment that can be transported by a stream that has a velocity of 50 cm/sec?What is the largest sediment that can be transported by a stream that has a velocity of 50 cm/sec?
Sand is the only sediment that could be transported at that velocity as others are heavy to be transported with the mentioned velocity
Explanation:
Answer:
All four planets: Mercury, Venus, Earth and Mars are inner planets or also referred as terrestrial planets. Those are the planets orbiting closest to the Sun.
Earth is the largest of the Inner Planets, with a diameter of 12,756 km and Mercury is the smallest with a diameter of 4,878 km (3,031 miles). They have solid surfaces and thin/no atmospheres. Mercury is one of the densest planets in the Solar System. Venus is the brightest object we see in the sky, has a thick toxic atmosphere and is the hottest planet. Earth is the only planet that has liquid water.Mars surface contains iron-rich materials and has the most interesting terrain: the surface is very old and filled with craters.
