Answer:
D- Topsoil, Subsoil, and Parent Soil
Answer: The number of H+ ions moving down the channel
Explanation:
Answer:
6.5 cm
Explanation:
Mechanical advantage is a measure of efficiency or performance of a tool or machine in terms of force amplification which is done by the machine or tool. In simple terms, it measures that at what extent the applied force is increased with the help of tool or machine.
Mathematically, it is the ratio of force produced by the tool or machine to the force actually applied to the tool.
In terms of effort length and resistance length, it is calculated as -
Mechanical advantage = 
Thus, Mechanical advantage = 
= 6.5 cm.
The green house effect is when their is too much pollution in the air. Cars, factories and industries cause a lot of pollution in the air which then causes the ozone to thin out which causes it to get hotter because the ozone is a layer that keeps the temperature not too hot or cold
Toward the end of depolarization, voltage-regulated <u>slow calcium</u> channels would open while the sodium channels close.
<h3>What is cardiac cycle?</h3>
Cardiac cycle can be defined as a complete heartbeat of the mammalian heart and it comprises sequential-alternating contraction and relaxation of the atria and ventricles, in order to allow blood flow unidirectionally (one direction) throughout the body.
<h3>The stages of cardiac cycle.</h3>
Based on scientific evidence, the cardiac cycle in living organisms happens in two (2) stages;
<h3>What is depolarization?</h3>
Depolarization of the mammalian heart is a process which involves an orderly passage of electrical current sequentially through the heart muscle within the four chambers (4) of the heart such as atria and ventricles.
Toward the end of depolarization of the mammalian heart, voltage-regulated <u>slow calcium</u> channels would open while the sodium channels close.
