grrr science I aint helping LOL! im kidding HERE hope this helllpppsssss! (:
Explanation:
Plants have two major structural systems: the root system and the shoot system. ... The shoot system transports water and nutrients to leaves and flowers. The leaves of the plant are the main location for photosynthesis. Plant reproduction occurs through pollination of the flower and fertilization.
Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on). Most plants are vascular, which means they have a system of tubules inside them that carry nutrients around the plant.
Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function.
<span>It's a proposition which states that the two species competing for the same resources cannot coexist if other ecological factors are constant. When one species has even the slightest advantage. One of them will always overcome the other one which will eventually lead to extinction of the other one.
Hope this helped!!</span>
A is correct because for cDNA first we need to have out mRNA sequence and we know that in prokaryotes they dont have mRNA and splicing mechine
