Biology
1 answer:
Darina [25.2K]3 years ago
7 0

Answer:

<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>

Explanation:

Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.

suppose you found a bone of a mastodon which had 6.25%c14and93.75%n14 how long ago did this animal die​
lisabon 2012 [21]

Answer:

t= 3886.18 years old

Explanation:

Whenever an animal dies de C14 and N14 begin to disintegrate in such a way that the proportion between C14 and C12 decreases, with a semi-disintegration period of 5.730 years, T. To get to know how long it takes an element to disintegrate, we must use this semi-disintegration period, which is the time it takes until the amount of the element is reduced to its half.  

We can find the age of the fossil, t, by using the next formula:

t = - (T x ln (C14))/ ln (2)

t = - (5730 x ln (0.625)/0.693

t= - (-2693.12)/0.693

t= 3886.18
