Mitosis. It is as well as meiosis, sometimes called the two nuclear division processes. Is this helpful?
Are determined by genetic variation
The answer is; B
Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.
This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
The answer is 200 cells per microliter
Fever, weight loss, and candida infections are symptoms of immunodeficiency. These symptoms only appear if the level of CD4+ count is below normal, resulting in disruption of the immune cells work. The threshold level of CD4 count to cause immunodeficiency symptoms is 200 cells per microliter.
