How can invasive species alter an ecosystems food web?
Harlamova29_29 [7]

Invasive species can either replace an organism from the ecosystem food web or replace it.  

Explanation:

  • Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
  • Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
  • So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.

The prolonged electrical depolarization of cardiac muscle cells that occurs during contraction is due primarily to the persisten
luda_lava [24]

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:

  1. The increase in intracellular sodium induces the release of Ca⁺⁺ from the sarcoplasmic reticulum.
  2. Calcium entry from the extracellular space through the voltage dependent Ca⁺⁺ channels.
  3. 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⁺⁺.
