Answer: Repolarization occurs Potassium ions continue to diffuse out of the cell after the inactivation gates of the voltage-gated sodium ion channels begin to close.
What is the problem, add a picture.
Genetic drift is the change in the gene pool
Explanation:
Both micro and macro evolution depends on processes like natural selection, genetic drift, speciation etc.
Genetic drift is the variations caused in the gene pool due to increase or decrease of alleles over time.
The variations in the phenotypes or traits of the fishes in the net are due to evolutionary adaptations developed over generations. The advantage of a dark color in differential reproduction and survival would have made to pass the dark color to the offsprings in each generation by making it the dominant allele.
Dark color helps the fishes to hide from their predators and also to attract their mates. Due to these reasons, the gene frequency of dark color becomes high and will cause an overall genetic drift in that species of fish.
Yes, Genetically Modified Organisms (GMOs) should be used to help meet the world’s food needs but with taking care of all the ethical concerns.
<h3>What are genetically modified organisms</h3>
Organisms whose genetic material i.e. genes are being modified by certain molecular biology techniques are known as genetically modified organisms. The genes which are manipulated or modified are known as transgenes therefore these organisms are also known as transgenic organisms.
<h3>Why should they be used to help meet the world’s food needs?</h3>
As the world’s population is rapidly increasing, there is a need for new technologies which can help meet this challenge. Currently, the agriculture which is practiced today is not sustainable, a lot of herbicides and pesticides are being used which has led to massive destruction of the lands.
So, genetically modified organisms become a solution to it.
