Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
Sea star and human. Because they are both at least stronger.

Information is received by a neuron through the dendrites and is transmitted toward other neurons through the axon. In cooperation axon and dendrites are a portion of neuron which is establish in the nervous structure. But they do have some opposing characters. The foremost variance among an axon and a dendrite is, dendrites obtain communications from other cells however axons permits communications from the cell body to supplementary neurons, muscles or glands. Dendrites are short split procedure while axon is one long procedure. Dendrites are frequent, multiple procedures of short length, the divisions are covered with spiny projections. The wideness of dendrite decreases as they divide and carry indications from pre-synaptic cell to the cell body. They control the degree of action possible made by the neuron. They convey electrical desire by the upstream neurons via synapses. Axon is an extended procedure which customs a protraction called axon hillock. The cytoplasm of axon is named axoplasm and it is proficient of transport the impulse left from the cell body.
