Vacuole. I hope this is it:)
Physical resources that are extracted from the ocean and are useful to humans include petroleum and natural gas.
<h3>What are physical resources?</h3>
- Physical resources are tangible items such as raw materials which are required by the humans for their need.
- Water, air, soil, rocks are all physical resources of the terrestrial and aquatic ecosystems.
- Land, water and air are necessary for our survival.
- Geological features like volcanoes, caves and fossils are also a part of physical resources.
- The dead and decaying remains of plants and animals over thousands of years in the oceans (marine system) form petroleum and natural gas which are used as fuels to power vehicles.
- Coal is obtained from the remains of plants over hundreds of millions of years ago in terrestrial ecosystem.
- Petroleum and natural gas are non renewable so we must use them judiciously.

Answer:
Chemical bonds of ATP
Explanation:
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups
<u>In the process of translation, the statement stands correct and applies are as follows:</u>
- The ribosome has two sub-units that work together.
- Amino acids are joined by peptide bonds.
- Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
- The order of the amino acids is determined by the mRNA which is transcribed from DNA.
Answer: Options A, B, C, and E
<u>Explanation:</u>
In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.
Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
ATP stands for Adenosine Triphosate.
ATP is the basic form of energy for living eukaryotic organisms.
