2. King's Bay, Florida is a popular stop for manatees in cold weather because of the warm spring waters. People travel from all over to view the manatees. They boat, kayak, dive, snorkel, and sometimes harass and endanger the manatees. King's Bay established a manatee protection area in 1980 and expanded the area in 1994 and 1998. These areas allow manatees to enter and leave freely but restrict people from entering. Based on the data in the table below, what conclusion can you draw about the effectiveness of these protections?

(LOOK AT PICTURE ATTACHED)

The manatee population and the number of visitors increased, so additional protections may be needed.
The protections were effective but should be removed because the manatee population is now too high.
The manatee population is not affected by visitors, so the current protections are adequate.
The protections were not effective and should be removed to allow manatees to migrate.

Population genetics is the study of _______.
Mrrafil [7]

According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.

<h3>What is population genetics?</h3>

It studies the origin, amount and distribution of genetic variability present in populations.

It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.

Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.

The fixed pattern of changes in membrane potential during an action potential is coordinated by the sequential opening and closi
baherus [9]
<h2>Na-K channels</h2>

Explanation:

  • Brief sequential change in the membrane potential of excitable cells after stimulus is called action potential whereas membrane potential represent charge difference across the membrane
  • In a typical neuron cell, membrane potential of cytoplasm is negative at rest and hence called resting membrane potential
  • Resting membrane potential of excitable cells is established by Na+ K+ pump and maintained by K+ leaky channels at rest
  • Phases of action potential includes: depolarization, repolarization, hyperpolarization and resting membrane potential
  • Depolarization starts when a threshold stimulus is applied on a neuron when via Na+ mechanically operated channels that trigger action potential
  • Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
  • Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels, voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
  • Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
  • Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channel
