Question

Write in brief about the senescence in Animals. 

Answer

Here are some key points about senescence in animals:

1. ageing is a natural process that occurs in all animals and is influenced by a range of factors such as genetics, environment, and lifestyle.
2. Senescence involves a gradual decline in physiological functions such as metabolism, immune function, and hormonal regulation.
3. Cellular changes associated with senescence include telomere shortening, DNA damage, and protein aggregation.
4. Age-related diseases such as cancer, neurodegeneration, and cardiovascular disease are more common in older animals.
5. The ageing process is influenced by both genetic and environmental factors, with some species living much longer than others.
