Answer:
G1 phase cell cycle arrest and apoptosis
Explanation:
According to Yan and colleagues 2009 article, cells that were transfected with microRNA-1/206 showed cell cycle arrest at the G1 phase and showed an increase in apoptosis (programmed cell death) which is important for synthesis of mRNA and protein. These processes have a direct effect on cell proliferation by decreasing it.
Answer:
B) sympathetic and parasympathetic
Explanation:
e autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
<span>Microevolution refers to changes in the genetic pool
of a species population. The changes in the genes (probably gene and allele frequencies)
are observed over short time periods hence are small changes. This is in comparison
to macroevolution that observes huge changes over longer time periods in the population that warrant that the new populations
is considered to be a new species</span>
<span>The zygote will have the complete or diploid number of chromosomes, which is 46. The two ways wherein meiosis increases genetic diversity in a species are crossing over and independent assortment of homologous chromosomes. </span>
