Natural selection leads to evolution because the strongest survive and pass on their genes
Dissecting microscopes used for the observation of larger objects and u can get a magnification of less than 100x.
<span>Dissecting microscopes are most often used by plant biologists

Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.
Explanation:
<span>However, these advancements that other people are talking about will not probably last for very long since much resources were used to exploit and overuse the natural resources we currently have. The question of what about the future populace who are significantly viable to live under this planet, 100 years from now? Isn't that claim sort of egotistical?
Exploitations lead to different global ecological changes like the occupation of the invasive species which can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number.
</span><span>Exotic species are a threat to biodiversity because they alter the ecosystem of that area. They share food and habitat resulting in unbalanced ecosystem. </span>
