In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.a. True
b. False


Answer 1

It is true that in the DNAisolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

What is DNA isolation?

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellularcomponents using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensicscience, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.

Answer: Ova

Explanation: When an egg cell and sperm cell join together, the fertilised egg cell contains 23 pairs of chromosomes. One chromosome in each pair comes from the mother, the other from the father.

Thomas and Julie wanted to find out which material would insulate theirteacher's coffee cup and keep the coffee hot for the longest period of

wrap, but they got the same results for both materials. Which of the below

Which list of words describes an action potential?all or none, neurotransmitters, membrane potential

membrane potential, neurotransmitters, electrical signals

electrical signals, all or none, neurotransmitters

all or none, membrane potential, electrical signals


All or none, membrane potential, electrical signals is list of words describes an action potential. Option 4 is correct.

An action potential is a rapid change in the electrical potential of a cell membrane. It is a wave of depolarization that travels down the axon of a neuron. Action potentials are "all or none" events. This means that they either occur fully or not at all.

Action potentials are triggered by changes in the membrane potential. The membrane potential is the difference in electrical charge between the inside and outside of the cell membrane. When the membrane potential reaches a certain threshold, an action potential is triggered. This threshold is called the refractory period.

Once an action potential is triggered, it travels down the axon of the neuron. The action potential causes the release of neurotransmitters at the synapse. Neurotransmitters are chemicals that allow neurons to communicate with each other. They bind to receptors on the next neuron, which can trigger another action potential. Option 4 is correct.
