A
. Leaves were trapped between layers of sediment millions of years ago, causing the imprint
Explanation:
The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.
Leaf imprints are often referred to as trace fossils.
- Trace fossils points to the different life activities an organism must have been engaged in.
- When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
- This gives a physical overview to the nature of leaf.
- Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
- Option C is completely wrong

A) Genetic drift is the random increase or decrease of genes in a population. Natural selection is not random.
Genetic drift is the change in the frequencies of alleles in a population due to chance events (random survival). Genetic drift exhibits strong effects in small populations and plays a smaller role the larger the population gets. Natural selection is the non-random change in the frequency of alleles in a population over time, because the change in frequency of the alleles is dictated by the different relative fitnesses that different alleles confer.
Granite soils in foothills and plains that are decomposing. Even when dried, locoweed is deadly at all times.
How can locoweed prevent self-poisoning?
The enzyme alpha-mannosidase, which is necessary for normal sugar metabolism in cells, is inhibited by the indolizide alkaloid swinsonine, which is present in all parts of the plant.
How can I remove locoweed?
The most effective method of reducing locoweed is foliar sprays, which penetrate through the leaves to the roots. The most typical method of treating locoweed is a mixture of picloram and 2,4D. A kind of weevil has just been shown to be able to consume the roots of plants and eradicate weeds.
