Answer: True

Explanation: The plasma membrane is a membrane the protects the cell and its environment. It regulates what goes inside and what comes out of the cell. .

Plasma membrane as a structure composed of multiple components, including phospholipid bilayer, carbohydrates, and other lipids. The phospholipids possess one head and two tails. The head is basically polar and hydrophilic (water-loving) while the tails are non-polar and hydrophobic (water-fearing).

The plasma membrane is decorated with proteins. Some protiens are extrinsic proteins that run halfway through the membrane, while others are called integral proteins that go entirely through the membrane. The function of these proteins is to serve as channels to allow the molecules to enter and leave the cell.

During depolarization, which of the following statements about voltage-gated ion channels is TRUE
Wewaii [24]

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.

Escribe lo que piensa de la siguiente suposición si es cierta o no: " Todas las semillas de una fruta sobrevivirán, se convertir
MissTica

Answer:

Esta suposición no es realista, muchas de las semillas no llegarán a la etapa adulta y por lo tanto no podrán generar nueva progenie

Explanation:

Acorde a la teoría de la evolución por selección natural planteada por Darwin, solamente aquellos organismos que se encuentren mejor adaptados al ambiente en el que viven podrán sobrevivir y de este modo perpetuar sus genes en la progenie. Este es un principio que aplica a todos los tipos de organismos vivientes (es decir, plantas, animales, bacterias, etc). Darwin definió a este proceso evolutivo como 'descendencia con modificación', donde aquellos organismos que se encuentren mejor adaptados a su ambiente transmitirán sus rasgos a la descendencia, mientras que aquellos que no se encuentren suficientemente adaptados no podrán sobrevivir.
