Answer:

(B). Brown algae and dinoflagellates.

Explanation:

In a phylogenetic tree, two species are considered as most closely related if they share a more common ancestor than the others. The nodes of tree represent the common ancestor, while the tips of branches represent species originated from that ancestor.

As in given tree, dinoflagellates and brown algae share a common ancestor as they evolved from the same ancestor, they are most closely related to each other.

Thus, the correct answer is option (B).

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.

Margaret [11]

Answer: The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. Instead, at the end of their lives, they will explode in a violent supernova, leaving behind a neutron star or black hole. ... Low- to medium-mass stars, such as the sun, will eventually swell up into red giants.
