Why is cancer rare when mutations happen constantly in cells?
Cancer is relatively rare despite constant mutations because most mutations are either harmless or repaired by the cell's robust DNA repair mechanisms. Additionally, the majority of mutations do not lead to uncontrolled cell growth, which is necessary for cancer to develop. Only a small fraction of mutations can give rise to cancerous properties, and even then, multiple mutations are typically required over time to enable a cell to become cancerous. Furthermore, the body's immune system often identifies and eliminates abnormal cells before they can proliferate.
Which is more likely to develop adaptations to a changing ecosystem a population that often has many mutation or a population that has few mutations?
A population that often has many mutations is more likely to develop adaptations to a changing ecosystem because they have greater genetic diversity to explore a wider range of traits that could provide a selective advantage in the new environment. This diversity increases the chances that some individuals will possess advantageous traits that allow them to survive and reproduce in the changing conditions.
Explain where mutations can develop at the cellular level?
Mutations can arise at the cellular level for a variety of reasons. The most common source of mutations is an error in the copying of genes, known as proofreading error. Mutations may also arise though the presence of a mutagen which can also cause a proofreading error. Similarly, UV light can damage the strands of DNA such that the attempt to fix the error can introduce a mutation. Finally, the chromosome itself can be the source of mutation either through breakage or anomalous linkage.
Why do plants scatter their seeds over a wide area?
That way the plant can have more space to grow and use resources
What causes cancer cells to develop?
Malignant tumors are a type of tumor that are cancerous, meaning they are able to spread to other parts of the body. These tumors contain cells that are not limited in their growth, which means that, if left unchecked, they will continue to spread until the victim is deceased. Most cancer cells develop their abnormalities by way of environmental factors, but 5 to 10% of cases are due to inherited traits.
Does age of onset affect prognosis for myopathy?
Progressive myopathies that develop later in life usually have a better prognosis than conditions that develop during childhood.
Which is more likely to develop adaptation to a changing ecosystem?
A population with few mutations will have more room in there genes to do mutations
Does puberty make mitochondrial disease worse?
Yes, puberty is notoriously difficult for mitochondrial disease patients. Mitochondrial Disease is a disease of Energy. Puberty is a time when your body uses an immense amount of energy to develop and grow.Visit UMDF.org or MitoAction.org to learn more.

What are the symptoms of Vesicoureteral reflux?
VUR alone does not usually cause symptoms. Symptoms develop when an infection has set in.

What is diagnosis of a drug overdose based on?
Diagnosis of a drug overdose may be based on the symptoms that develop, however, the drug may do extensive damage to the body before significant symptoms develop.
