A river or steam / moving body of water
Answer:
option A
Explanation:
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
but i searched about option d this is the answer i got
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant
<u><em>In vascular plants, stems are the organs that hold plants upright so they can get the sunlight and air they need. Stems also bear leaves, flowers, cones, and secondary stem</em></u>
option A is the answer
Given that the energy plant is to be built on the bank of the river, it will affect the local watershed by contaminating the water flowing in front of it. Option ll is correct.
The Construction of an energy plant on the banks of a river implies a <em>hydro power plant</em>. This means that the plant will harvest the energy of the flowing river to create <u>electricity</u>. A turbine is used to transform the <u>kinetic energy of the moving water into the mechanical energy needed for electricity</u>. The problem with this idea is the pollution.
The process of generating electricity from the <u>kinetic energy of the water comes at a cost. </u>This cost is in the form of <em>waste</em> that is produced. This waste is often very toxic to life. Some energy plants of this kind produce a great amount of waste, which can result difficult to dispose of and thus is often dumped back into the river, contaminating the river that flows after the power plant.

A. A Catalyst is defined as speeding up a chemical reaction, and breaking Hydrogen Peroxide apart chemically is a chemical reaction which abides by allowing a catalyst being present to speed up the reaction. Reactions occur faster with a catalyst because they require less activation energy
