Answer:
A. Bones provide structure and support to the body, while muscles move the bones.
Explanation:
Answer: 100 grams of the parent isotope will remain after one half life.
Explanation:
Mass of the isotope present at initial stage = 
The mass of the parent isotope left after the time ,t=N
Time taken by the samle ,t = 
The half life of the sample :
![\ln[N]=ln[N^o]-\frac{0.693}{t_{\frac{1}{2}}}\times t_{\frac{1}{2}}](https://tex.z-dn.net/?f=%5Cln%5BN%5D%3Dln%5BN%5Eo%5D-%5Cfrac%7B0.693%7D%7Bt_%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%5Ctimes%20t_%7B%5Cfrac%7B1%7D%7B2%7D%7D)
![2=\frac{[N_o]}{[N]}](https://tex.z-dn.net/?f=2%3D%5Cfrac%7B%5BN_o%5D%7D%7B%5BN%5D%7D)
![[N]=\frac{N_o}{2}=\frac{200 g}{2}=100 g](https://tex.z-dn.net/?f=%5BN%5D%3D%5Cfrac%7BN_o%7D%7B2%7D%3D%5Cfrac%7B200%20g%7D%7B2%7D%3D100%20g)
100 grams of the parent isotope will remain after one half life.
I don’t believe this is true. I don’t think you can recycle EVERYTHING so I would put false.
I hope this helped! :-)
The cells, organelles, and the tissues of the body are measured in micrometers. The size of the cells, tissues, and various organelles are very small. Majority needs the help of microscope to be seen. Therefore, the larger units of the metric system cannot be used to measure their sizes. Hence, the smaller unit, such as the micrometer is used for their measurement purpose.
The given blank can be filled with micrometers.
