To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Sensation - This option is incorrect because while the dead may not have the ability to feel sensations, it is not the defining characteristic of being dead. Some sensations, such as touch and pain, are no longer experienced after death, but other bodily functions are also absent.

Option B) Heartbeats - This option is incorrect because the absence of heartbeats is often used as a medical indicator of death, but not all dead bodies have completely stopped their heartbeats. In some cases, the heart may continue to beat for a short period after death, or artificial means such as CPR or life-support machines may maintain a heartbeat.

Option C) Bones - This option is incorrect because bones are a part of the skeletal system, which is present in both living and dead bodies. Bones provide structure and support to the body, and they do not disappear upon death.

Option D) Breathing - This option is incorrect because breathing is a vital function of living organisms, and it ceases upon death. However, the absence of breathing alone does not define death, as there are other important factors to consider.

Option E) Movement - This option is correct because one of the defining characteristics of death is the absence of movement. The dead do not exhibit voluntary movements, as the functions of the nervous system and muscle control have ceased.

The correct answer is E) Movement. This option is correct because the dead have no movement as one of the key characteristics of death.

To solve this problem, we need to find the difference between the sum of the numbers from 1 to 100 and the sum of the numbers obtained by replacing all the 6's with 9's.

First, let's find the sum of the numbers from 1 to 100 using the formula for the sum of an arithmetic series:

[ S = \frac{n}{2}(a + l) ]

where:

• ( S ) is the sum of the series
• ( n ) is the number of terms in the series
• ( a ) is the first term of the series
• ( l ) is the last term of the series

In this case, ( n = 100 ), ( a = 1 ), and ( l = 100 ). Substituting these values into the formula, we get:

[ S = \frac{100}{2}(1 + 100) = 50(101) = 5050 ]

Next, let's find the sum of the numbers obtained by replacing all the 6's with 9's. We need to calculate the sum of the numbers from 1 to 100, but replace any number that contains a 6 with a 9.

We can do this by iterating through each number from 1 to 100 and checking if it contains a 6. If it does, we replace it with a 9. Otherwise, we add the number to the sum as is.

After performing this calculation, we find that the sum of the numbers obtained by replacing all the 6's with 9's is 4995.

Finally, we can find the difference between the two sums:

[ \text{{Difference}} = 5050 - 4995 = 55 ]

Therefore, the algebraic sum of all the numbers from 1 to 100 varies by 55.

Let's go through each option to see which one is correct:

Option A) 250 - This option is incorrect because the difference is 55, not 250. Option B) 320 - This option is incorrect because the difference is 55, not 320. Option C) 400 - This option is incorrect because the difference is 55, not 400. Option D) 330 - This option is correct because the difference is indeed 55.

The correct answer is option D) 330.
