Answer:

Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.

5. a. What technology produced the results illustrated here, and what is this

notsponge [240]

The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.

Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.

In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).

The steps involved in gel electrophoresis include the following:

Extraction of deoxyribonucleic acid (DNA).

DNA isolation and amplification.

Addition of deoxyribonucleic acid (DNA) to the gel wells.

Application of an electric current to the gel.

The separation of DNA bands based on molecular size and charge.

Deoxyribonucleic acid (DNA) bands are stained.

What causes hyperpolarization of a neuronal membrane?.

zalisa [80]

The cause of hyperpolarization of a neuronal membrane is the flow of positive ions out of the opening channel of the neuronal membrane.

What is hyperpolarization?

This can be defined as when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.

The cause of hyperpolarization is when the flow positive ions out of the opening channel of the neuronal membrane can cause hyperpolarization.

Examples: Opening of channels that lets K+ flows out of the neuronal membrane or let's CL- flow into the neuronal membrane can cause hyperpolarization.
