Transfer RNA (tRNA) carries amino acids to the site of protein synthesis.
In general , tRNA is responsible for carrying amino acids to the ribosomes, the site of protein synthesis, during the process of translation. Each type of tRNA molecule is specific to a particular amino acid. The tRNA binds to the appropriate amino acid and delivers it to the ribosome, where it is incorporated into the growing polypeptide chain according to the sequence of codons in the messenger RNA (mRNA) molecule.
This process ensures that the correct amino acids are assembled in the correct order to form a functional protein. Transfer RNA is a type of RNA molecule that plays a crucial role in protein synthesis. It has a unique cloverleaf-like secondary structure, with three important regions: The acceptor stem: This region is at the bottom of the cloverleaf and is where the specific amino acid attaches to the tRNA.
The anticodon loop: This region contains three nucleotides that are complementary to the codon on the messenger RNA (mRNA) during translation.

b. They are substrates for aerobic metabolism and if increased in the blood show that the cardiac muscle is not functioning normally.
c. These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
d. They are by-products of anaerobic metabolism (glycolysis) and if increased indicate that the heart is not receiving oxygen.

Individuals 2, 3, 4, and 5 are affected by Leigh's disease. It is passed down from the mother to her offspring through the mitochondria.
Leigh's disease is a mitochondrially inherited disease,The pedigree shows the presence of Leigh's disease in three generations, indicating that it is maternally inherited.
Individuals 2, 3, 4, and 5 are affected by Leigh's disease because they show symptoms of the disease, such as seizures, ataxia, and impaired reflexes. Their symbols on the pedigree should be shaded in to indicate that they are affected.
Individuals 1, 6, 7, and 8 are not affected by Leigh's disease because they do not show any symptoms of the disease. Their symbols on the pedigree should be left unshaded to indicate that they are unaffected.
Individuals 4 and 6 both had children, but the information provided does not indicate whether their offspring were affected by Leigh's disease or not. Therefore, their symbols on the pedigree should be left unshaded.

Deforestation, pollution and loss of natural resources all are possible due to human involvement in devastating the environment i.e. urban sprawl. Thus, correct answer is option D.
Further Explanation:
Urban sprawl is another word used for urbanization. This refers to the migration of the population from the populated towns as well as cities to the reduced density of residential development. This shift generally leads to reduction of natural resources and supplies. The final result is the spreading of a city over more and more rural land. This refers to the expansion of poorly planned and low-density development. This spreads over large amounts of land and puts long distances between storage home and work, and thus, creates high segregation between commercial and residential uses having harmful impacts on the individuals living in such regions. The wildlife and ecosystems are displaced.
Some argue that this has its benefits like making local economic growth. However, it has many uninvited consequences for the environment as well as residents like higher water and air pollution, elevated jams and fatalities in traffic, and loss of agricultural capacity. There is also an increased car dependency.

Explanation:
The answer is that cnidarians lack triploblastic development. Cnidarians, such as jellyfish, sea anemone, and hydra, exhibit diploblastic development. This means that they have only two germ layers: the ectoderm and the endoderm. To understand triploblastic development, let's break it down. Triploblastic development refers to the formation of three germ layers: the ectoderm, the mesoderm, and the endoderm. These germ layers give rise to different tissues and organs in the body. In contrast, cnidarians lack the mesoderm layer. The mesoderm layer is responsible for forming muscles, connective tissues, and other internal structures. Since cnidarians do not have this layer, they are considered diploblastic. Let's use an example to illustrate this. Imagine you have a triploblastic organism, like a human. In a human, the mesoderm layer gives rise to muscles, which allow us to move. But in cnidarians, since they lack the mesoderm layer, they do not have true muscles. So, to summarize, cnidarians lack triploblastic development because they do not have the mesoderm layer. Instead, they exhibit diploblastic development, with only two germ layers: the ectoderm and the endoderm
