Neurotransmitters can __________________ receptors to turn them on or __________________ them to stop them from transmitting.
NikAS [45]

Neurotransmitters can excite receptors to turn them on and stop them from transmitting.

A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain your heartbeat, as well as receive and process all the information your body receives from other internal body components and your environment. From one neuron (nerve cell) to the following target cell, neurotransmitters transfer chemical signals, or "messages."

The majority of estimates suggest that the neurotransmitter transient lasts only a few hundred to several hundred of microseconds, indicating that post-synaptic activation is marked by a significant degree of non-equilibrium.

Which enzyme is mixed with a DNA sample before gel electrophoresis
Svetach [21]

Answer:

Restriction enzyme

Explanation:

  • Gel electrophoresis is a process or a technique in which fragments of DNA  are separated in terms of their sizes.
  • <em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
  • When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.

Maurinko [17]

Answer:

El cuadro no está presente pero las diferencias principales entre células eucariotas y procariotas son:

Eucariotas:

Tienen núcleo

Tienen organelas

Tienen Vacuolas

Tienen Citoesqueleto

Tienen Cloroplastos

El ADN está asociado a proteínas

El ADN es lineal

Presentan mitocondrias

Presentan un sistema de endomembranas

Procariotas:

No tienen núcleo

No tienen vacuolas

No tienen cloroplastos

No tienen organelas

El ADN no está asociado a proteínas

El ADN es circular

Presenta mesosomas

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
