Answer:
Differential reproduction leads to a change in allele frequencies over time. This occurs because of natural selection favoring "successful" individuals that produce more viable offspring.
The sickle-cell allele is maintained in populations exposed to malaria through balancing selection, since heterozygous individuals have protection against the disease.

Explanation:
Neurons are the nerve cell that acts as the basic structural unit of the nervous system. Neurons helps in the transmission of nerve impulse and transmit the signal into different parts of the body.
There are basically four types of microscopic neuron : unipolar, bipolar, multipolar and pseuounipolar neuron. Star-shaped neurons are not found in the microscopic description of neuron.
Thus, the correct answer is option (a).
The evolution of molecular biology has made possible to establish a new classification of all organisms according to their DNA, and it's called phylogenetic classification.This classification groups living beings according to their kinship, established according to anatomical, physiological and behavioral criteria and especially genetic, based on the similarity of genes between species.
This made it possible to discover kinship ties between species of which there is no suspicion of any morphological link between them, something which the old classification (the traditional classification) was incapable of doing (and this proves the importance of the DNA and genes in organisms classification.
Let me help you here :)
Start by presenting yourself, your name, where you from, etc. Then you can explain why is it important to complete all your assignments and study to get good grades... You can also talk about how High School will reflect in your future and applications for colleges. In your story write how important is to always pay attention in class and listen to your teacher.
Hope this helps!!
