Evolutionary<span> thought, the conception that </span>species<span> change over time, has roots in antiquity - in the ideas of the </span>ancient Greeks<span>, </span>Romans<span>, and </span>Chinese<span> as well as in </span>medieval Islamic science<span>. With the beginnings of modern </span>biological taxonomy<span> in the late 17th century, two opposed ideas influenced </span>Western<span> biological thinking: </span>essentialism<span>, the belief that every species has essential characteristics that are unalterable, a concept which had developed from </span>medieval Aristotelian metaphysics<span>, and that fit well with </span>natural theology<span>; and the development of the new anti-Aristotelian approach to </span>modern science<span>: as the </span>Enlightenment<span> progressed, evolutionary </span>cosmology<span> and the </span>mechanical philosophy<span> spread from the </span>physical sciences<span> to </span>natural history<span>. </span>Naturalists<span> began to focus on the variability of species; the emergence of </span>paleontology<span> with the concept of </span>extinction<span> further undermined static views of </span>nature<span>. In the early 19th century </span>Jean-Baptiste Lamarck<span> (1744 – 1829) proposed his </span>theory<span> of the </span>transmutation of species<span>, the first fully formed theory of </span>evolution<span>.</span>
I believe it is "Bacilli" because the question give you a hint by saying "<span>rod shaped structures", Bacilli very similar to this description.

Answer:
The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:
1) root pressure (osmosis)
2) capillary action (adhesion)
3) evapotranspiration (cohesion)
Explanation:
The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.
Hope this helps.
Renewable resources are the resources which can never be exhausted. The difference between fresh water and coal is that, fresh water is a renewable resource, while coal is a nonrenewable resource.
<h3>What are the types of natural resources?</h3>
Natural resources are materials that people utilize from the Earth.
Generally, resources can be grouped under two categories, i.e. renewable and nonrenewable resources.
- Renewable resources: The resources that can be grown again or in other words the resources that can never be exhausted are called renewable resources. Examples solar energy, fresh water, trees, etc.
- Non-renewable resources: These resources are present in a fixed amount in environment or one can say that these can never be replenished if exhausted once. Example coal, oil, fossil fuels, etc.
Thus, the correct option is D.
