Answer:
AUG (Methionine)
Explanation:
The process of protein synthesis occurs in two stages; transcription and translation. Transcription produces mRNA molecules from a DNA template. The mRNA's sequence is then read in a group of three nucleotides called CODON in the ribosome during the translation process.
Each Codon, of which there are possible 64, specifies an amino acid (building blocks of protein). Translation in the ribosome occurs when the ribosomal subunit binds to an mRNA molecule and a transfer RNA also binds using its anticodon (complementary to mRNA codon) to the AUG codon on the mRNA.
This AUG codon is regarded as the START CODON because it is the codon that initiates the commencement of translation. It encodes Methionine.
B. They have a true body cavity.
C. They have two germ layers.
C. They have two germ layers.
Members of the phylum Porifera are not considered diploblastic because they do not have two germ layers. Instead, they have a unique level of organisation where their cells do not form tissues or organs. The term 'diploblastic' correctly applies to organisms like jellyfish or sea anemones that have two germ layers producing various tissues and organs.
Members of the phylum Porifera, often referred to as sponges, are not considered diploblastic because they do not have two distinct germ layers. Instead, they possess a unique level of organization in which their cells do not form tissues or organs. Confusingly however, they do have two layers of cells, but these do not equate to the germ layers seen in true diploblastic organisms like cnidarians.
In a true diploblastic organism, such as a jellyfish or sea anemone, the two germ layers - the ectoderm and endoderm, produce the various tissues and organs of the organisms. The jellyfish's tentacles and mouth, for instance, are produced by the ectoderm, while its digestive cavity is produced by the endoderm.
So, the statement that clarifies the term 'diploblastic' with respect to members of Porifera is not accurately represented by any of the provided options, since they are not truly diploblastic. The closest would be 'C. They have two germ layers', but this is still not technically correct for the reasons mentioned above.

Biotechnology allows for determining the degree of relatedness among individuals.
Answer:
Increase occurs in fresh water input.
Decrease occurs in the salinity of the bay.
Explanation:
The low rate of fresh water input and the presence of high amount of salts in water decreases the population of producers such as grasses in bay ecosystem. Due to this decrease, the population of the marine animals decreases due to the low availability of food for herbivorous organism that lives in the bay. The negative feedback mechanisms will be achieved if increase occurs in fresh water input and decrease occurs in the salinity of the bay.
