Do most echinoderms spend a lot of time caring for their young? explain.
andreyandreev [35.5K]
Echinoderms do not spend time caring for their young ones.
They reproduce by sexual means, that is the combination of genetic materials from two separate individuals (male and female). The males provide the sperm and the females provide the eggs for reproduction. The sperms and eggs are propagated into water column, and fertilization takes place in the open water. Echinoderms commonly, leave their eggs and provide no parental care to the eggs. They don't take care of their young ones at all, however, some sea urchins incubates their eggs in special little pouches.

The generation of an action potential in a neuron requires the presence which type of membrane channels
valentina_108 [34]

The right answer is: voltage-gated channels

Ionic channels are membrane proteins that allow the selective passage of the cell membrane by ions (Na +, Ca2 +, K +, Cl-, ...) following the electrochemical gradients. They play a vital role in cellular excitability, triggering and propagation of action potential. They intervene in the coupling excitation-contraction and excitation-secretion. Ion channel selectivity is based on the adequacy of ion size and charges with the structure and amino acid sequence of the channels.

Among these channels, there are voltage-gated channels.

These are ion channels whose opening is activated by the membrane potential.

These dependent volumetric channels are characterized:

- by the selectivity of the ions (Ca2 +, Na +, K +, Cl-, ...)

- by their conductance

- by their activation domain (significant depolarization to low)

- by their kinetics of inactivation (slow, fast or transient)
