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.
Its super effective when something is coming towards your eyes because binking can prevent debris from entering.
Answer: Fovea Centralis
Explanation:
Fovea Centralis is located at the center of the retina. It is responsible for interpreting visual detail with accuracy, by sending visual information to the ganglion cells, which eventually transmits them to the brain.
Thus, Fovea Centralis is the answer
Answer:
This question lacks options, the options are:
A. The sequence of DNA determines the structure of lipids, which produce phenotypes.
B. The sequence of DNA determines the structure of proteins, which produce phenotypes.
C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.
D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.
The answer is B.
Explanation:
DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.
An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).
the answer is B the pores must be connected to each other
