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.
Answer:
Actually, a leaf's design must be open enough to capture sunlight for all-important photosynthesis. It also needs to make sure a leaf is shaped in a way that ensures the pores — called stomatae — can soak up enough carbon dioxide, which helps fuel that process. How is a leaf adapted for photosynthesis? Leaves have a large surface area so more light hits them. ... The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf. The leaf also has air spaces which allow better diffusion of carbon dioxide into the leaf.
Explanation:
Answer:
a gene is the different forms of a trait a segment of DNA that is the basic unit of heredity
Explanation:
Humans get D vitamin from sunlight. the plants perform photosynthesis and grow , we eat those fruits and vegetables grown in the plants. so indirectly we humans and other animals are benifitted from sun sunlight . flesh eating animals eat herbivores animala so they are also benifitted
Answer:
The heads (the phospho part) are polar while the tails (the lipid part) are non-polar.Its like a front and back type of location with those.
