Answer:
2.048 x 10^6 No. Of Copies
Explanation:
The DNA replication in a PCR works exponentially by using the 2^n where n represents the number of cycles.
For one molecule of DNA = 2^11 = 2048 No. Of Copies
For 1000 Molecules of DNA = 1000 x 2048 = 2.048 x 10^6 No. Of Copies
Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
Soil is a mixture of weathered rock and organic material.
