There is nothing there to answer
Answer:
Letter <u>A</u> indicates the <u>epidermis</u>, which is the outer layer of the root.
Explanation:
The internal structure of the eudicot root consists of <em>three concentrical layers</em>: The <u>epidermis</u><u>,</u> the cortex, and the central vascular cylinder.
The epidermis is the outer layer of the root. It <em>covers the totality of the root surface</em>, <em>absorbs water</em> and <em>minerals from the soil,</em> and <em>protects the internal tissues</em>.
The <em>cortex</em> occupies a big part of the root and its <em>located under the epidermis</em>. The <em>most internal cell layer</em> of the cortex is called <em>endodermis</em>.
The <em>vascular cylinder</em> is composed of <em>vascular tissues</em> -the xylem and the phloem- that is <em>surrounded by</em> one or more cell layers called <em>pericycle</em>. The xylem looks like a <em>cross of big cells</em> in the center, and the phloem occupies the spaces between the pericycle and the xylem.
Microbes as they tend to produce rapidly on a surface of other microbes such as bacteria and fungi.
Energy can neither be created nor destroyed. It is transformed from one to another form.
The example of potential energy raised ball over the round and example for kinetic energy is water is used for moving the turbine to produce electricity.
Explanation:
This process happens because of conservation of energy. According to the rule of the conservation of energy, energy can’t be created nor destroyed. It is simply converted from one to another form. It simply means this system always need same amount of energy.
Due to motion of object or particle an energy is formed is called kinetic energy and due to relative position of energy an energy is formed is called potential energy.
