Answer:
Polarity and Non-polarity of molecules depend upon the electronegativity. The theory of electronegativity lies in entire inorganic chemistry. The more electronegative an atom, the more it seeks electrons. If one atom is more electronegative than others, it can form an ionic bond or a polar covalent bond.
Explanation:
Answer:
Professional gardeners often soak seeds in hydrogen peroxide before planting them in order to increase the germination percentage or to reduce germination failure. When the seeds are soaked in hydrogen peroxide, the seed coat becomes soft and enzymes present in the seed becomes active. Due to soaking of seeds, the seed takes less time to germinate. So that's why gardeners uses this method.
Osmosis is spontaneous net movement of solvent molecules
Mitosis= type of cell division that results in two daughter cells having the same number and kind of chromosomes
Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
Answer:
Explanation:
In RNA (ribonucleic acids), the nitrogen bases are:
- Adenine
- Guanine
- Cytosine
- <em>Uracil</em> (there is thymine in DNA, but not in RNA)
The bases pair like:
- Adenine (A) with Uracil (U)
- Cytosine (C) with Guanine (G)
So, the base pairs for RNA are <u>A with U </u>and <u>C with G</u>
