The dirt doesn’t, but soil contains bacteria- fungi, and the dead/decaying waste byproducts. So the answer is technically yes
Answer: The glomerulus is filled with blood via an afferent arteriole and it is ensheathed in visceral SQUAMOUS EPITHELIUM.
Explanation: Glomerular wall consists of fenestrated endothelium, thick basal lamina and podocytes' pedicels separated by filtration slits of controllable width. These permit the filtration of water solutes into a capsular space between glomerular epithelium and the parietal squamous epithelium of Bowman's capsule.
The United States, Great Britain, and Japan a<span>t the end of World War I,</span> all began to make the alot of programs of capital ship construction. This huge building began to create a naval arms race..The Kellogg-Briand pact was a bilateral treaty to state and point out the<span> war that was caused by the expansionist aggression and anger
so it was the purpose of the pact

Answer:
The prolonged electrical depolarization of cardiac muscle cells -that occurs during contraction- is due primarily to the persistent influx of calcium ion
Explanation:
The action potential of the heart muscle is longer with respect to skeletal muscle (around 300 milliseconds), and this is due to the activity of calcium (Ca⁺⁺ ) in the intracellular compartment.
The initial depolarization of cardiac muscle fiber depends on the entry of sodium (Na⁺) into the cell. However, for the action potential to occur and be maintained, Ca⁺⁺ must increase its cytoplasmic levels, which depends on:
- The increase in intracellular sodium induces the release of Ca⁺⁺ from the sarcoplasmic reticulum.
- Calcium entry from the extracellular space through the voltage dependent Ca⁺⁺ channels.
- The entry of extracellular Ca⁺⁺ causes the release of more Ca⁺⁺ ions by the sarcoplasmic reticulum, further increasing its intracellular concentration.
This is how the ion that guarantees the duration of the action potential of the cardiac muscle cell is the Ca⁺⁺.
