Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.
Answer: it’s A
explanation:
The correct answer to the question about why can a Benedict solution be used to distinguish between a glucose and a sucrose is letter A. Benedict's Solution is used to test the presence of reducing sugar. Glucose is a reducing sugar while Sucrose is a non-reducing sugar since it has a glycosidic bonds between their structure that hinders the formation of open chain. In the end, Sucrose stuck at its cyclic form.
organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
