Answer:
C) tRNA
Explanation:
RNA is also known as Ribonucleic acid and has three types namely:
messenger RNA (mRNA)transfer RNA (tRNA)ribosomal RNA (rRNA)The rRNA forms the core of the protein and helps catalyze the joining of the protein chains.
The mRNA work hand in hand with the tRNA as they send coded instructions to the tRNA. The tRNA then decodes the message sequence into a protein.
The tRNA does this by transferring the appropriate amino acid to the end of the growing amino acid chain.

A potential answer to a research question is a(n)
A. theory
B. observation
C. question or problem statement
D. hypothesis
A research question is the basis of the experimental analysis of the subject matter. A hypothesis is said to be the potential solution to a research question. Thus, option D is correct.
What is a hypothesis?The hypothesis has been defined as the supposition that acts as the basis of the research and experiment and has been constituted of some evidence and facts to formulate the research question.
It acts as a starting point for any investigation and research and must be falsifiable. They should be testable in order to determine the verifiability of the research topic. If the tested hypothesis is correct then further research is conducted.
It can also be defined as an educated guess that is based on some prior knowledge and facts that are deduced through experiments.
Therefore, the hypothesis is a potential solution.

Answer:
Paramecium is a genus of eukaryotic, unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds
Paramecium is a unicellular organism with a shape resembling the sole of a shoe. It ranges from 50 to 300um in size which varies from species to species. It is mostly found in a freshwater environment.
It is a single-celled eukaryote belonging to kingdom Protista and is a well-known genus of ciliate protozoa.
As well, it belongs to the phylum Ciliophora. Its whole body is covered with small hair-like filaments called the cilia which helps in locomotion. There is also a deep oral groove containing not so clear oral cilia. The main function of this cilia is to help both in locomotion as well as dragging the food to its oral cavity.

ribosome
A cell membrane
B chloroplast
C cell wall
Answer:
cell wall
Explanation:
cell wall provide support for plant
The cell wall provides rigidity to a plant cell.
Cell wall :Cell wall is the outer layer surrounding the cell membrane. Cell wall is flexible, but it provides strength to cells. The main component of the plant cell wall is cellulose. Cell wall provides shape to the cell. It also protects the cell against some physical and mechanical damage.
Cell wall maintains turgor pressure in the cell. Cell wall is also present in fungi but it is absent in animals. ribosome helps in protein synthesis. It manufactures proteins for the cell. Cell membrane is also called plasma membrane. It helps in entry and exit of molecules.
Chloroplast is the chlorophyll containing cells. It is present in leaves of the plant cells. It helps in the process of photosynthesis.
Therefore, The cell wall provides rigidity to a plant cell.

Explain how all the properties of water are related. Provide an example to describe the interconnectivity of each property. Be sure to include hydrogen bonding, polarity, surface tension, capillary action, cohesion, adhesion, high specific heat, and expansion upon freezing.
Water is a liquid that is tasteless, odorless, and also has a standard temperature of 25°C.
Water is known to be a polar inorganic compound which is a universal solvent. The molecules of water form hydrogen bonds with themselves. The hydrogen bonding of water causes other properties such as the high heat capacity that water has, high boiling point of 100°C. Also, water molecules possess strong cohesive forces because of their ability to form hydrogen bonds.In conclusion, water is amphoteric which means that it has both properties of acid and base.

Answer: You, Digestive system, Stomach, Epithelial Tissue, Parietal cells.
Explanation:
From largest to smallest: 1. You, 2. Digestive System, 3. Stomach, 4. Epithelial Tissue, 5. Parietal cells.
The human body encompasses all organs and systems, making it the largest in this sequence.
The digestive system, a major anatomical system, follows, responsible for processing food. Within the digestive system, the stomach is an organ that plays a vital role in digestion.
Epithelial tissue lines the stomach and other organs, representing a smaller organizational level. Lastly, parietal cells are specific cells found in the stomach lining, making them the smallest entity in this context.
This ordering reflects the hierarchical organization from the whole human body to its organs, tissues, and cellular components, illustrating the structural complexity of the human organism.

The most important reason for learning about environmental systems is due to the fact that we should know what's going on in the world around us. If we were to travel to Asia, we should know the forests that lie there to pack appropriately. It's also important to just be aware of how the world works. It's also good to know what rock type you'll be walking on, so you can pack shoes accordingly. Overall, it's better to know the world around you than to live in ignorance.
The human GM-CSF gene and the mouse GM-CSF gene vary by more than 60% in their DNA sequence. However, when scientists place the human gene into mice, it functions properly. What best explains why this happens?
A. The difference between gene sequences does not change the structure of the proteins.
B. The resulting proteins made by the human gene are similar to the proteins made by the mouse gene.
C. The mouse DNA is a mutated form of the human GM-CSF gene.
D. Mice can make human protein without the use of the human GM-CSF gene.
Answer:
hello i think it's The resulting proteins made by the human gene are similar to the proteins made by the mouse gene.
Explanation:
I hope this helps
The human gene when placed into the mice functions properly because the resulting proteins made by the human gene are similar to the proteins made by the mouse gene.
What is the GM-CSF gene?The Granulocyte-macrophage stimulating factor or GM-CSF are glycoproteins secreted by immune cells. These are secreted by the GM-CSF gene. These factors function as cytokines in the body
This factor causes the activation of macrophages in small numbers and produces a rapid immune response against a pathogen. GM-CSF also influence mature cells like neutrophils to enhance their migration. Therefore GM-CSF plays a great role in the activation of the immune system against a pathogen and promotes its defence mechanisms.
Thus, even if the human GM-CSF and mouse GM-CSF vary by up to 60 per cent in their DNA sequence, human GM-CSF functions properly in nice because their resulting proteins are similar to each other.
Therefore correct option is B.
