Identify the steps of the retrovirus life cycle by dragging the labels to the appropriate targets.
Answers
The steps of the retrovirus life cycle include attachment, entry, reverse transcription, integration, transcription and translation, assembly, and budding.
The retrovirus life cycle involves several steps: (1) Attachment: The retrovirus attaches to the target cell surface using its viral envelope protein and host cell receptors. (2) Entry: The virus fuses with the cell membrane, allowing its viral RNA and enzymes to enter the cell. (3) Reverse Transcription: The viral RNA is reverse transcribed into DNA by the viral enzyme reverse transcriptase. (4) Integration: The viral DNA integrates into the host cell genome with the help of the enzyme integrase. (5) Transcription and Translation: The integrated viral DNA is transcribed and translated to produce viral proteins and genomic RNA. (6) Assembly: New viral particles are assembled using viral proteins and genomic RNA. (7) Budding: The assembled viruses bud off from the host cell membrane, acquiring their viral envelope. The newly formed viruses can go on to infect other cells and repeat the cycle.

Answers
Based on the information provided, the correct statement is:
c. Anil and Bala will both be happy to move from the Pareto efficient (I, T) to the "fairer" Pareto efficient outcome (I, I).
:
Pareto efficiency refers to a state where no individual can be made better off without making someone else worse off. In this scenario, the outcomes are represented by the choices of using Integrated Pest Control (IPC) or Terminator (T).
From the given information, we can deduce that (I, I) is the Pareto efficient outcome. This means that both Anil and Bala are satisfied with this outcome, as neither of them can be made better off without making the other worse off.
On the other hand, (T, T) is the only Pareto inefficient outcome. This indicates that there exists an alternative outcome, (I, I), where both Anil and Bala would be happier.
However, the given information does not provide any details about the outcome (T, I) and its relation to (T, T) in terms of Pareto dominance. Therefore, statement d. (T, I) Pareto-dominates (T, T) cannot be determined based on the given information.

What are the 3 functions of RNA?
Answers
RNA, or ribonucleic acid, is a molecule that plays a critical role in the biological processes of cells. RNA performs a variety of functions, but the three main functions are:
Protein synthesis: RNA acts as a template for the synthesis of proteins. The process of protein synthesis is known as translation, and it involves the transfer of genetic information from DNA to RNA and then to proteins.
Gene regulation: RNA can also play a role in regulating gene expression. For example, microRNAs (miRNAs) are small non-coding RNAs that bind to specific sites on messenger RNAs (mRNAs) and inhibit their translation. This can lead to the repression of protein production from specific genes.
Catalytic activity: Some types of RNA molecules have catalytic activity, meaning that they can carry out chemical reactions. The most well-known example of this is ribozymes, which are RNA molecules that have enzymatic activity.
In detail, the first function of RNA is protein synthesis. This process starts with the transcription of DNA in the nucleus of the cell. During transcription, an enzyme called RNA polymerase reads the DNA code and produces a complementary RNA molecule. This RNA molecule, called messenger RNA (mRNA), then exits the nucleus and travels to the ribosomes in the cytoplasm. There, it serves as a template for the synthesis of proteins. The sequence of nucleotides in the mRNA determines the sequence of amino acids in the resulting protein.
The second function of RNA is gene regulation. MicroRNAs (miRNA) are small non-coding RNAs that are transcribed from specific genes and then fold into specific stem-loop structures. Once formed, miRNA bind to specific sequences on target messenger RNAs (mRNAs) and inhibit their translation, leading to repression of protein production. This is one way that cells can control which genes are actively producing proteins at a given time.
The third function of RNA is catalytic activity. Ribozymes are RNA molecules that have enzymatic activity and can catalyze chemical reactions. The most well-known example of this is the ribosome, which is a complex of RNA and protein molecules that catalyzes the formation of peptide bonds between amino acids during protein synthesis. Additionally, some viruses also have RNAs that act as enzymes to catalyze replication of viral genomes.
In summary, RNA plays a crucial role in the biological processes of cells, performing three main functions: protein synthesis, gene regulation, and catalytic activity.

Answers
Cancer is a complex group of diseases that may be subdivided into benign or malignant cells and is referred to as a malignant neoplasm.
The difference between benign and malignant tumors is that benign tumors are non-cancerous and don't spread to other parts of the body, while malignant tumors are cancerous and can spread to other parts of the body.Benign tumors, unlike malignant tumors, grow slowly and do not spread to other parts of the body.
They can, however, be life-threatening if they press against vital organs or tissue. Benign tumors may also cause discomfort and can develop into cancerous tumors over time. In contrast, malignant tumors grow quickly and spread to other parts of the body via the lymphatic system or bloodstream, leading to cancer.
Malignant cells are highly destructive and aggressive, and they can spread to other parts of the body, making it difficult to cure. The most common types of cancer include breast cancer, lung cancer, and prostate cancer. Early detection and treatment of cancer are critical for a positive prognosis.
Furthermore, there are numerous factors that can contribute to cancer, including lifestyle choices, environmental factors, and genetic predispositions. Some of the most significant cancer risk factors include smoking, poor diet, sedentary lifestyle, and exposure to harmful chemicals.

Has larger diameter branches Has smaller diameter branches Resistance is high Resistance is low
Answers
The true statements for the conducting zone include: Has larger diameter branches and Resistance is low on the other hand, the true statements for the respiratory zone include: Has smaller diameter branches and Resistance is high
Explanation:
The conducting zone includes the bronchi, bronchioles, and terminal bronchioles. The respiratory zone, on the other hand, includes the respiratory bronchioles, alveolar ducts, and alveoli.
Both airflow and resistance vary significantly between the conducting and respiratory zones. The conducting zone has a larger diameter than the respiratory zone.
It is because of the larger diameter that there is low resistance to airflow. As we go from the conducting zone to the respiratory zone, the diameter of the airways becomes smaller, and the resistance to airflow increases. Smaller diameter branches belong to the respiratory zone.
