<span>The correct answer is true; insufficient flexibility does indeed increase an athlete's risk of an injury. This is because a less flexible muscle is more likely to be pulled or torn by movement than one that is able to be moved in a greater range of motion. Thus, it is important for athletes to work of their flexibility.</span>

- It is responsible for controlling all the cellular activities.
- It carries all the genetic information for growth , development , metabolism , reproduction and behaviours.
- It regulates protein synthesis.
- It includes genetic changes and brings variation which is essential for organic evolution.
- Mitochondria [ power house of cell ]
- They help in synthesis of fatty acid and amino acid.
- They also regulate calcium ion concentration inside the cell.
- They are the site of thermogenesis [ heat generation ]
- It acts as a cytoskeleton and gives mechanical support.
- It helps in lipid synthesis.
- It helps in glycogenolysis.
- It forms nuclear envelope during cell division.
- They help in synthesis of protein and hence they are called protein factories.
- They also store protein for a temporary time.
Hope I helped ! ♡

<em>1. Some tumors are benign, which means they form in only one spot without spreading to surrounding tissue. Malignant tumors are cancerous and can spread to nearby tissue.</em>

<em>2. A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can. In most cases, the outlook with benign tumors is very good. But benign tumors can be serious if they press on vital structures such as blood vessels or nerves.</em>

<em>3. Although some tumors are benign and consist of noncancerous cells, others are malignant. Malignant tumors are cancerous, and the cells can spread to other parts of the body.</em>

<em>4. Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis.</em>
