Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
Answer:
primary succession only occurs on bare rock
Explanation:
Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).
I hope you get the answer!!!
It is an example of a withdrawal reflex.
Answer:
Medical Detoxification
Explanation:
Detox or detoxification is the process of safely and systematically withdrawing from a substance such as drugs or alcohol. For many, it’s an important first step in recovery, allowing the body to withdraw from potentially dangerous substances without risking hospitalization.
Many drugs have significant withdrawal symptoms once you quit using them, you tend to experiencing considerable discomfort and pain. Without proper medical attention, these withdrawal symptoms can become dangerous to your health and even become life‐threatening.
Objectives of Detoxification include
1. Evaluation‐the testing of substances in the bloodstream, their concentrations and any co‐occurring mental or physical conditions that may accompany substance abuse as well as other medical and social assessments.
2. Stabilization‐assisting patients through the withdrawal process towards a stable and substance‐ free state.
3. Fostering Entry into Treatment‐preparing clients to enter formal treatment and providing encouragement and support.
