The surface area is 1,620
<h3><u>Answer;</u></h3>
When particles were pulled together so tightly they combined.
<h3><u>Explanation</u>;</h3>
- The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas.
- It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.
- According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.
Answer:
A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod
Explanation:
Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.
Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.
Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.
The cliffs become over saturated with water allowing it to go down the mountain, causing catastrophic damage
Chemical energy: When animals eat plant, they get the chemical energy in the plants stored as sugar.Mechanical energy: Carbon dioxide rising through the air gains mechanical energy (as well as gravitational potential energy).Thermal energy: The heating of fossil fuels releases the energy stored inside.Electrical energy: Burning fossil fuels creates electrical energy for us to use.
