All cells have a plasma membrane, ribosomes,cytoplasm, and DNA
Answer:
In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate. Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old.
And that's how after rounding we know that earth is 4.5 years old.
Answer:The secretion of aldosterone is directly stimulated by adrenoglomerulotropin.
Explanation:
Aldosterone plays an important role in the regulation of systemic blood pressure through the absorption of sodium and water. The lipid factor(adrenoglomerulotropin) which is obtained from pineal extracts selectively stimulates secretion of aldosterone.
Answer:
The correct answer will be option D.
Explanation:
DNA replication is a complex process which forms the exact copy of the DNA molecule from the existing DNA. This process takes place during the synthesis phase or S-phase of the cell cycle which takes place in the cytosol of prokaryotes and nucleus of the eukaryotes.
The most common way of producing replicas of the DNA molecule is through semi-conservative mode in which each strand of DNA is synthesized from both the strands of the parental DNA using as a template.
Thus, option D is the correct answer.
