Answer: I thinks it’s a. A guess about a scientific idea
Explanation:
On earth, water can exist as a solid,a liquid, or a gas because "the Earth is at an ideal temperature due to its distance from the Sun".
<u>Option: </u>A
<u>Explanation:</u>
Water can occur at a specific temperature of 273.16 K and pressure of 611.2 Pa in three various states i.e. solid, liquid and gas, and this phase is considered to be triple point water. At such a temperature and pressure the water keeps moving from solid to liquid phase and vice versa.
The average global temperature of Earth at aphelion is about 4 degrees Fahrenheit, or 2.3 degrees Celsius higher than at perihelion. This results as the the Southern Hemisphere has more oceans while the Northern Hemisphere has more land, which make the heating up of the land easier and faster.
Because of the Earth's revolution, a solar day is slightly longer than a sidereal day. In every day life, we use solar time. The Earth must rotate an extra 0.986 degrees between solar crossings of the meridian. Therefore in 24 hours of solar time, the Earth rotates 360.986 degrees.
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
Answer:
All living cells must carry out cellular respiration. It can be aerobic respiration in the presence of oxygen or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells.
