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.
Answer: The scientific method is cyclic.
Explanation: Scientific methods is the systematic way of using knowledge , hypothesis , observation , theories and experiments , to give us understanding for the questions.
Scientific method is always cyclic as it involves several steps. Cyclic way give us better understanding about facts and whole phenomena.

Wilts, wood rot, sooty molds, rusts, and smuts. These are all types of plant diseases caused by Fungi. For example, dry rot is a wood decay caused by certain species of fungi that digest parts of the wood which give the wood stiffness and strength. All of them are plant diseases caused by fungi.
The extraocular or extrinsic eye muscles, considering their relatively small size, are incredibly strong and efficient. There are the six<span> extraocular muscles, which act to turn or rotate an eye about its vertical, horizontal, and antero-posterior axes: medial rectus (MR), lateral rectus (LR),</span>
