The stigma of the flower must be elevated (by the style) away from the ovary to avoid self pollination or contamination. The stigma is covered with sticky substances so that pollen can easily attached themselves to it.
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.
The GI tract consists of mouth, esophagus, stomach, small intestine, large intestine, and anus,
<h2>Pathway of digestion</h2>
The GI tract is a series of hollow organs that is joined in a long, twisting tube from mouth to the anus. The GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus are the hollow organs while on the other hand, the liver, pancreas, and gallbladder are the solid organs of the digestive system.
The food enters through mouth which moves after chewing to esophagus then to the stomach. After digestion, all the nutrients are absorbed whereas waste materials are send to the small and then large intestine and finally to anus.

Answer:
Aware and unaware.
Explanation:
Memory is storage of any kind of information in the brain. Two main types of memory are short term memory and the long term memory.
Explicit memory may be defined as the memory that can be recalled intentionally by an individual and individual is aware about the memory. Implicit memory is the functional memory that cannot be recalled easily and individual is unaware about the memory.
Thus, the answer is aware and unaware.
