Answer:

Hyperpolarization

Explanation:

When the membrane potential becomes more negative than the resting potential, the membrane is hyperpolarized. Hyperpolarization is inhibitory in nature and decreases the ability of the neuron to generate a neural impulse. During signal transmission at a chemical synapse, binding of neurotransmitters to the receptors stimulates the opening of ligand-gated ion channels. The flow of ions changes the voltage across the membrane and may cause depolarization or hyperpolarization. For instance, the opening of Cl– or K+ channels causes hyperpolarization.

Answer:

Hello, The DNA fingerprinting technique and development and comparison of physical fingerprints can be the methods used for the purpose of solving crimes and identification of missing person. The DNA fingerprinting can be done from the physical evidences such as blood, sweat, hair, tissues, teeth and other material obtain at crime scene. These can be compared with the suspects, victim and missing persons so as to establish their identity. The physical fingerprints can be developed on the scene of crime and compared with the requested specimen from suspect, victim and the missing person or in case of impersonation to establish the desired identity.

<em>Hope This Helps!</em>

guapka [62]

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

  • In water molecules hydrogen bonds provides a special dipole - dipole attraction.
  • Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
  • This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
  • This makes the molecule of water polar.
  • By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.
