Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Chromosomes are thread like molecules composed of DNA.They are present as a dense structure and get organised as Chromosomes during cell division.
Answer:
Photosynthesis
Explanation:
The producers represent the first trophic level in an ecosystem. They include all autotrophic organisms. By using their photosynthetic pigments they trap light energy and convert it into chemical energy. They do so through photosynthesis, taking up carbon dioxide and water from the environment. Producers are a source of energy for all other living organisms.
Answer: the correct answer is (B) Whether others of the closely related group of plants also produce histidine in large quantities
Explanation:
This is a CAUSAL argument.
In a causal argument, A and B are observed together, and the CR concludes that A CAUSES B.
Premise = A and B are observed together:
A cultivated herb produces histidine and is able to grow in metal rich soils.
Conclusion = A causes B:
Histidine CAUSES the herb to be able to grow in metal rich soils.
One way to strengthen the conclusion that A causes B is give ANOTHER SUPPORTING EXAMPLE that links A to B.
