7 0

Explanation:

1. cell membranes are partialy permeable, only allowing passage to some certain molecules.

2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.

3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.

3. Nombra las reacciones que ocurren en el paso de<br> Alfacetoglutarato a succinato
Shkiper50 [21]

Answer:

Hidrólisis y oxidación.

Explicación:

La hidrólisis y la oxidación son las reacciones que ocurren en el paso del alfacetoglutarato a succinato. En el quinto paso hay una hidrólisis del grupo tioéster de CoA en la que los átomos de los compuestos se rompen y luego sustituyen sus elementos miembros. Esta reacción de hidrólisis libera energía y se hace un ATP a partir de ADP. En el paso 6, succinato a fumarato es una oxidación para poner en el doble enlace significa que FAD se reduce a FADH2. Entonces podemos decir que la hidrólisis y la oxidación son las reacciones que ocurren en el paso de Alfacetoglutarato a succinato.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar. true false
Norma-Jean [14]

Answer:

TRUE

Explanation:

The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.

The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.

The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.

The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.

There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.

However, the basic nerve cell is very similar in all animals.
