Recombinant DNA is DNA that has been created using intelligent design methods to modify a base DNA molecule using DNA component elements from other strands of DNA of other organisms. There are a wide range of possible DNA elements that can be removed, added to or otherwise modified to produce the new recombinant form.
Recombinant DNA technology clearly is genetic engineering using intelligent design as the selection and placement of the added DNA components must be planned and precisely selected and placed to accomplish the intended result. It does not happen naturalistically.
There are numerous aspects of the growing technology of recombinant DNA that modify DNA to serve the purpose of the intelligent designers, including wide ranges of research, medicine, synthetic biology, potential commercial products and even scientific curiosity.
Answer:
True
Explanation:
Animals can be categorized into 3 based on body symmetry
- <em>Those without any body symmetry (asymmetrical)</em>
- <em>Those with bilateral body symmetry (bilateria)</em>
- <em>Those with radial body symmetry (Radiata)</em>
Animals can be categorized into 2 based on number of embryonic germ layer;
- <em>Those with two layers - endoderm and ectoderm (diplobastic)</em>
- <em>Those with three layers - mesoderm in addition to ectoderm and endoderm (triploblastic)</em>
Animals can be categorized based on presence/absence of body cavity or coelom;
- <em>No body cavity - acoelomates</em>
- <em>False body cavity - pseudocoelomates</em>
- <em>True body cavity - coelomates</em>
Animals can be categorized into 2 based on characteristics of embryonic development;
- <em>Deuterostomes</em>
- <em>Protosomes</em>
Answer is B
Increase the odds by creating relationships among organisms.
Answer: The given statement is True.
Food chain can be described as the sequence of transfer of energy and matter among different organisms present within an ecosystem.
It starts with producers ( occupying the first trophic level), which are consumed by consumers in a successive manner ( primary consumer→ secondary consumers→ tertiary consumer or decomposers).
Therefore, producers are beginning link in a food chain whereas decomposers occupy the last level in a food chain.
