Question
Which of the following statements is/are CORRECT?Select all that apply. Evidence of similarities in lifespan of twins indicates genes contribute to longevity. Ageing is inevitable, deleterious, and progressive. As tissues age they become less able to regenerate and maintain homoeostasis. The greatest impact of ageing comes from its effects on lipids and proteins in ageing cells.
Solution
All of the statements are correct:
-
Evidence of similarities in lifespan of twins indicates genes contribute to longevity: This is correct. Studies have shown that genetics can play a significant role in determining lifespan, and twins, especially identical twins, often have similar lifespans.
-
Ageing is inevitable, deleterious, and progressive: This is also correct. Ageing is a natural process that everyone goes through, and it is associated with a gradual decline in bodily functions and overall health.
-
As tissues age they become less able to regenerate and maintain homeostasis: This is correct as well. As we age, our body's ability to repair and regenerate tissues decreases, and this can disrupt homeostasis, or the body's ability to maintain a stable internal environment.
-
The greatest impact of ageing comes from its effects on lipids and proteins in ageing cells: This is correct. Ageing can cause changes in the structure and function of proteins and lipids in cells, which can lead to a variety of age-related diseases and conditions.
