A researcher determines an organism to be eukaryotic, unicellular, and autotrophic. In which taxonomic group should this organis
Aleksandr-060686 [28]

According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.

<h3>What is the kingdom protista?</h3>

It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.

Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.

Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

Warmer oceans would mean less dissolved CO2 as well as other gases such as oxygen in the global ocean. Lower CO2 would result in a decrease in photosynthesis of autotrophs living in the oceans.

An action potential involves potassium ions moving ________ the cell and sodium ions moving ________ the cell.
Alecsey [184]

An action potential involves potassium ions moving <u>outside </u>the cell and sodium ions moving <u>inside </u>the cell.

<h3>how does it action potential work?</h3>

Neurons have a negative concentration gradient most of the time, meaning there are more positively charged ions outside than inside the cell. This regular state of a negative concentration gradient is called resting membrane potential. During the resting membrane potential there are:

  • more sodium ions (Na^+ ) outside than inside the neuron
  • more potassium ions (K^+ ) inside than outside the neuron

The concentration of ions isn’t static though! Ions are flowing in and out of the neuron constantly as the ions try to equalize their concentrations. The cell however maintains a fairly consistent negative concentration gradient (between -40 to -90 millivolts). How?

  • The neuron cell membrane is super permeable to potassium ions, and so lots of potassium leaks out of the neuron through potassium leakage channels (holes in the cell wall).
  • The neuron cell membrane is partially permeable to sodium ions, so sodium atoms slowly leak into the neuron through sodium leakage channels.
  • The cell wants to maintain a negative resting membrane potential, so it has a pump that pumps potassium back into the cell and pumps sodium out of the cell at the same time.
