This structure is called the epiglottis. This flexible leaf-shaped cartilage serves as a flap that covers the larynx to prevent food and liquids from entering the airway and the lungs. It is open when we breathe which allows air to enter into the larynx.
Answer:
B. It is a nucleic acid
F. It allows parents and their young to have similar characteristics.
Explanation:
The genetic material refers to the molecule which acts as the coding material of the organism as it contains the code of protein and thus controls the basic function of the life.
The genetic material of the organism belongs to a class of molecule called nucleic acid as they are found in the nucleus of the cell. There are two types of nucleic acids called DNA and RNA.
The genetic material gets passed from the parents to the offspring through reproduction therefore the offsprings develop the same character as of their parents.
Thus, the selected options are correct.
True t<span>he only exception to organisms with different genetic codes are identical twins. Otherwise all organisms have differences in their genetic sequences that make them to at least a small degree unique</span>
