<h2>Option-3</h2>
<h3>Hope it helps you </h3>
Answer:
C
Explanation:
Interphase is the uniform phase for all cells division'. It signifies the begin of any cell cycle division. it is the period of prolong rest by the cells to prepare for the long journey of cell division. It involved replication of DNA, of organelles to be distributed in the daughter cells, accumulation of food resources .,
It is made up of the G1, for normal growth of cells and function of cells, doubling of organelles numbers.
S=synthesis stage, for DNA and genetic material replications
and the G2 phase growth resumption and preparation of cells division.
Therefore since all cells must undergo Interphase and carry out all the above processes prior to cell division, this stage(interphase) must be uniform to all cells.
Answer:
Cell membrane of prokaryotes and Inner mitochondria of eukaryotes
Explanation:
Electron transport chain is a part of oxidative phosphorylation which is the third step of aerobic cellular respiration in living organisms. The ETC is a complex of proteins and mobile electron carriers. It occurs when electron is being transferred from one electron carrier to another, starting from NADH and FADH2. A proton pump which is used to synthesize ATP is generated at the end.
This ETC process occurs in the cell membrane of prokaryotic cells due to the fact that they lack a membrane-bound Mitochondrion. ETC occurs in the inner membrane of the mitochondria called CRISTAE in eukaryotic cells.
Answer:
Hypothesis
Explanation:
In the scientific method used by scientist, The Hypothesis has a tentative or proposed explanation that gives report of an observed or measured phenomena. The hypothesis is usually based on previous observations which fails to be explained by available scientific theories. It is the starting point for further investigation that can be tested through experimentation.
Bacteria released oxygen into the atmosphere
