Answer #1

Cell death is Apoptosis.The signal for cell death may come from the cell itself or from neighbouring cells.When the cell is in stress due to DNA repair...or cell cycle is stopped in cell cycle check points...In any case if the cell has not the ability to handle the corrections the only way is Apoptosis.This programmed cell death needs energy.But if cell is not going to Apoptosis pathway ,that cell may progress to tumors later. whenever cell has a problem related to check points p53 activated. Disruption of p53 leads to check point defects and later genomic instability

Genetics:Pick a specific tumor suppressor gene or oncogene and explain how this gene can lead to or prevent cancer. Be sure to focus on the mechanism of how your chosen gene impacts the cell cycle. You can alternatively pick a virus that has been associated with cancer and explain how that virus impacts the cell cycle and ultimately leads to cancer. In laymen's terms please, this is a litlle confusing to me, thank you

"A Bug against Obesity" Eating too much and not doing exercise causes Obesity. When we consume more calories, in the form of sugars and fats, and not burn off these by doing exercise or physical activity, then this surplus energy will be stored as fat in our body. Obesity develops gradually overtime, the reason could be due to poor diet and lifestyle, lack of physical activity. Role of Microbiome in Obesity: Microbiome (probiotics) are important for health benefits and they...
