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.
The ability of a monkey to be able to exchange gases with its environment and deliver oxygen throughout its body is through the activities of the respiratory system.
<h3>What is respiratory system?</h3>
The respiratory system is defined as one of the body systems that are made up of a network of tissues and organs that aid in the exchange of carbon dioxide and oxygen.
The oxygen passes from the environment into the nostrils. It is then conveyed by the trachea to the bronchi and arrives at the alveoli where the oxygen is delivered to the body cells.
Therefore, the ability of a monkey to be able to exchange gases with its environment and deliver oxygen throughout its body is through the activities of the respiratory system.

Answer:
These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection.
Explanation:
Cophyly is the process when a parasite and host speciate together.
If blood flukes were to exhibit strict cophyly over millions of years, you would predict that blood flukes would- evolve in a manner that is exactly in the same way as the evolution of their host. Evolution is a process when something evolves over a period of time.
