Answer: d. exoskeletons are external to the soft tissues, and endoskeletons are internal
Explanation:
The skeleton can be define as the body part of the living beings which act as a supporting structure which maintains the posture and provides the supporting framework to the body. The exoskeleton is the skeletal structure that protects the body from outside. It encloses within it the soft tissues and organs of the body. It is the characteristic feature of the invertebrates. It is the external feature of the body. It also provides protection against the predator. The endoskeleton is the skeletal structure which serves as a attachment point for the muscles. It is the internal feature of the body.
Answer:
Three reading frames
Explanation:
Translation of mRNA always happen in one direction from the 5' end to the 3' end of the RNA strand.
Reading frame refers to the grouping of three consecutive bases to form a codon that can constitute an amino acid.
There are six possible reading frames in any nucleotide sequence.
Three from the 3' to the 5' end and three possible reading frames from the 5' to the 3' end.
As mentioned earlier, translation in mRNA happens in one direction therefore the three possible reading frames are;
- 5'- C AGA UCU AAU GCU UAU CGG AU-3'.
- 5'- CA GAU CUA AUG CUU AUC GGA U-3'.
- 5'- CAG AUC UAA UGC UUA UCG GAU-3'.
Cells do not blink in the same way because the amount of proteins between cells is unequal and the stage of each protein can be different between cells.
<h3>What is a protein?</h3>
- They are molecules present in living beings.
- They are essential molecules for the maintenance of the organism.
- They are macromolecules made up of amino acids.
Proteins are subject to the emission of green light when certain products are applied to cells. However, even similar cells from the same organism will not emit this light equally due to the difference between the amount and stages of the protein in each cell.

Answer:
C) commensalism
Explanation:
Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.
The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.
Parasitism is similar to this but the other organism is harmed in the process.
