Cellular fermentation takes place:
anaerobically
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
Longer the electrical wires mean _______________ voltage drop.
greater
Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.
What is a micrometer used for?
measuring the diameter of cylindrical objects with high precision
Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.
The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed from the hardening of molten rock?
igneous
The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.
Which of the following statements about electrical resistance is true?
the more resistive the conductor is the slower electron flow will be
Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
When the clouds become too saturated with water, the water is released as precipitation in the form of:
snow
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
Simplify (9a)(8ab) + (7a2)(8b).
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
(9a)(8ab) + (7a2)(8b)
(9 x 8)(a x a x b) + (7 x 8)(a2 x b)
(72)(a1+1 x b) + (56)(a2b)
72a2b + 56a2b
128a2b
Stratus clouds are __________clouds characterized by horizontal layering with a broad flat base.
low-altitude
Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.
