What are the roles of the parasympathetic nervous system and sympathetic nervous system in maintaining everyday homeostasis?

Biology

Answer: The parasympathetic nervous system and sympathetic nervous system play opposite roles

Explanation:

To ensure a stable internal environment (homeostasis) is achieved, the parasympathetic nervous system (PNS) and sympathetic nervous system (SNS) play OPPOSITE roles.

The PNS dominate during relaxed periods and stimulates the

- liver to break down glycogen

- constriction of bladder to pass out urine

- increases heartbeat

- dilate pupils etc

The SNS, in contrast dominate in times of emergency or stressful periods and do the EXACT opposite of the processes mentioned above.

Thus homeostasis is maintained

Using evidence from the Sea Star Wasting Disease case study, explain how change in allele frequency over time (evolution) happen
Vikki [24]

Due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.

<h3>Allele and allele frequency </h3>
  • An allele is one of an alternate form of a gene.
  • Allele frequency is the percentages of each of the different alleles of a particular gene in a population.

Changes in allele frequency that occur over time because of one or more evolutionary factors such as:

  • genetic drift,
  • gene flow,
  • mutation,
  • non-random mating,
  • selection, etc.

The change in allele in the sea star wasting disease was due to genetic drift which are random change in allele frequencies that occurs in small populations occurring due to such factors as disease.

<h3>Evidence of allele frequency change in sea star wasting disease</h3>

1. Mutation and reproduction results in a variety of genes passed on and carries by individuals of a population.

  • The changes that occcured at gene Locus 1048 and 1166 due to mutation helped the post-SSWD starfish to survive and reproduce giving rise to offspring with those changes.

2. Organisms who can survive, thrive, and reproduce will increase in number.

The about 20% post-SSWD starfish that survived due to the change in their allele were able to survive and reproduce rapidly giving rise to offspring such that the individuals in the population have almost risen to pre-SSWD numbers.

Therefore, due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.

In the classic Meselson and Stahl experiment, E. coli are first grown in 15N-enriched media (0th generation) and, subsequently,
mars1129 [50]

Answer:

The correct answer is - option e.)

Explanation:

The experiment that was performed by Meselson and Stahl was created to prove that DNA replication is a semiconservative process.

When Bacteria grow on 15N media they incorporate the isotype of nitrogen and after few generations, the culture moved to 14N media where it incorporates as they replicate in semi-conservative mode and one DNA strand comes from the Parent DNA.

The right option for question one is Option (e) Run as one band, at a position expected for DNA containing a 14N:15N ratio equal to 1.

Goshia [24]
Sean, who weighs the least of the three, will have the highest blood alcohol concentration (BAC).

The less a person weighs, the more they will be affected by a given amount of alcohol. People of the same weight, even the same gender, individuals with a lower percentage of body fat will have lower blood alcohol concentration than those with a higher percentage of body fat.

Hope this helps! :)
