Biodiversity loss from species extinctions may rival pollution and climate change impacts. Species extinction and loss of biodiversity could be as devastating for the earth as climate change and air pollution. That's the finding of a new study by a group of scientists from nine countries.
The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams
<h3>How to determine the number of half-lives </h3>
We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:
- Half-life (t½) = 96 years
- Time (t) = 270 years
- Number of half-lives (n) =?
n = t / t½
n = 270 / 99
n = 2.8125
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 30 grams
- Number of half-lives (n) = 2.8125
- Amount remaining (N) =?
The amount remaing can be obtained as follow:
N = N₀ / 2^n
N = 30 / 2^2.8125
N = 6.61 grams

Answer: A. Plant
Explanation:
Plants have some of the most of complex cells of living organisms because they have different roles and structures to enable the plant to survive.
These include cells like the Parenchyma, Collenchyma, Sclerenchyma, Xylem and Phloem cells. Xylem cells for instance are complex cells located within the vascular tissues of plants and help transport water and minerals to the rest of the plant from the roots. Xylem cells look long and tracheal which is to enable them carry out the aforementioned roles.
