Science is
a process we use to better understand how the world works
running experiments
studying chemical reactions
learning about life
The Correct Answer is A
A. a process we use to better understand how the world works: Science is a systematic process that involves observation, experimentation, and analysis to explain natural phenomena. It provides a structured way of building knowledge, testing ideas, and refining our understanding of the world.
B. running experiments: Experiments are an important part of science, but they represent only one tool within the broader scientific method. Science also involves forming hypotheses, making observations, analyzing data, and drawing conclusions beyond just running experiments.
C. studying chemical reactions: Studying chemical reactions is part of chemistry, which is a branch of science. However, science as a whole encompasses many fields, such as biology, physics, astronomy, and earth science, making it far broader than only chemical processes.
D. learning about life: Learning about life is the focus of biology, which is one area within science. While biology is a major scientific discipline, science overall includes both living and non-living systems.

Correct Answer is B
Explanation
A. Aquatic: Aquatic refers to environments or organisms related to water, but it does not describe a chemical process in which bonds are broken.
B. Hydrolysis: Hydrolysis is the reaction where water is used to split covalent bonds, breaking larger molecules into smaller subunits. This process is common in digestion and cellular metabolism.
C. Dehydration (or condensation): Dehydration involves removing water to form covalent bonds between molecules, which is the opposite of hydrolysis and results in larger compounds.
D. Hydratic: Hydratic is not a recognized term in chemistry for describing bond-breaking reactions, and it does not apply to hydrolytic processes.
Correct Answer is B
Explanation
A. budding: During budding, new viral particles exit the host cell gradually without destroying it, but viral synthesis continues during this stage to produce components for new virions.
B. latency: In latency, the virus remains dormant within the host cell with little or no viral synthesis occurring. The genome persists in the host without active replication until reactivated.
C. lytic replication: In the lytic cycle, viral synthesis is highly active, producing viral proteins and genomes that ultimately cause cell lysis and release of new virions.
D. persistent infection: A persistent infection involves continuous viral replication at low levels, so viral synthesis is ongoing, not suspended.
E. oncogenesis: Oncogenesis refers to virus-induced cellular transformation leading to uncontrolled cell growth, but viral synthesis may still continue depending on the virus type.
