Answer:
B
Explanation:
Light shows duality i.e it shows properties of both particle as well as wave.
Answer:
The options are
A. secondary structure ... hydrogen bonds
B. secondary structure ... peptide bonds
C. tertiary structure ... hydrogen bonds
D. primary structure ... covalent bonds
E. tertiary structure ... covalent bonds
THE CORRECT ANSWER IS A.
A. secondary structure ... hydrogen bonds
Explanation:
The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups
-NH and C = O
At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.
The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.
Answer:
The answer to your question is below
Explanation:
1.- Prophase
2.- Metaphase
3.- A
4.- centrosomes
5.- Interphase
6.- D, A, C, F, E, B
7.- Animal cells, because plant cells have a cell wall that is a rigid structure that can be divided but gives support to the plant cell and in this picture, the cells do not this structure.
8.- Interphase
9.- Because cells can reproduce and newborn cells replace the old ones.
LUCA the last universal common ancestor; it is exist in 3.5 billon years ago in the paleoarchean era, a few hundred million years after the earlier fossils evidence of life.
<u>Explanation:</u>
It is the single celled bacteria like organisms living in volcanic era. The three domain of the life are Archaea, bacteria, Eukaryotas. The observation that member of the single gene family are found in the all three domain of life.
It is suggested that the progenitor gene that give rise to the family member existed in the LUCA , before the time that the three domain diverged.
