How might spontaneous generation be possible in a reducing environment? Question options: The reducing environment was created b

y the abundance of methane, which contains carbon. Because all life is organic, and organic molecules are all carbon-based, these molecules were the source of the spontaneous generation of life. Without oxygen, biological molecules, such as amino acids do not easily break down. As a result, they could have formed a "soup" of organic molecules in the oceans of the past, allowing spontaneous generation to occur. The concentration of nitrogen in the atmosphere created this reducing environment. Because nitrogen is present in amino acids, nucleic acids, and lipids, this environment favored conditions that eventually formed life through spontaneous generation. With high concentrations of carbon dioxide, biological molecules could have performed photosynthesis and pumped oxygen into the air in sufficient amounts over about 2 billion years, making spontaneous generation possible.

18. Wind speed on Earth is reduced by which?
Genrish500 [490]

Answer:

Temperature reduces the wind speed on earth.

<u>Explanation:</u>

  • Wind speed is an atmospheric quantity that causes the wind to flow from high to low level due to a change in temperature.
  • Wind speed is controlled by the pressure gradient factor and it increases the wind speed with increase in pressure gradient.
  • Wind speed decreases with an increase in temperature value as it absorbs the heat developed in the system and wind gets slowed down.
  • Wind speed is measured in velocity and anemometer is used to measure the rate of wind speed.

A sled with no initial velocity accelerates at rate of 5.0 m/s^2 down a hill . How long does it take the sled to go 45 m to the
Leya [2.2K]

The time taken by the sled to reach 45 m to the bottom is 4.24 s.

The sled's initial velocity <em>u</em> is zero. It has an acceleration <em>a</em> of a value 5 m/s² down the hill and it travels a distance <em>s</em> equal to 45 m down the hill.

Use the equation of motion,

s=ut+\frac{1}{2} at^2

Substitute 0 m/s for u and rewrite the equation for t.

t=\sqrt{\frac{2s}{a}}  \\ =\sqrt{\frac{2(45 m)}{5.0m/s^2} } \\ =4.24s

The sled takes a time of 4.24 s to reach the bottom of the hill
