The answer is <span>a frameshift deletion at the beginning of the gene.
The frameshift deletion means that due to the deletion, the reading frame will be changed. Because of this, changed mRNA will be synthesized and translated into altered protein. It is known that codon is a triplet (a set of three nucleotides), that code for certain amino acid. The earlier in the sequence the deletion occurs, the protein will be more severely affected.
For example, if codons on RNA are THE BIG BAD DOG and the frameshift deletion happens on the first triplet (earlier in the sequence), the changed sequence will be TEB IGB ADD OG. If </span>the frameshift deletion happens on the third triplet (later in the sequence), <span>the changed sequence will be THE BIG ADD OG.</span> This way, if the<span> frameshift deletion occurs at the beginning of the gene,</span> the more codons will be changed and in turn, they will code different amino acids.
The echinoderm with long spines
belongs to the class Echinoidea which includes sea urchins, heart urchins, cake
urchins and sand dollars. This spine serves as their protective mechanism from
predators. The spines are joined to the skeleton and muscles surround it. The muscles
enable them to swivel its spines from predators.
Answer:
A. only one parent and results in offspring that are identical to the parent.
Explanation:
Asexual reproduction creates an identical copy of the parent typically, in which the genes are copied directly, and the body parts are cloned. There may only be variations depending on the influences of the outside nature, but typically they are identical to the parent.

D. membrane bounded organelles
