Practical unit of sciences is an undertaking that tests our understanding of the theoretical part of the unit and the goals to be achieved thereafter. Generally, the practical are meant to deepen our understanding of what is learnt in class. Bio 100 Lab Quiz #1 will broaden your understanding of this. Take up the challenge. Good luck.

• 1.

### A __________ is a challenge to an assumption.

Explanation
A problem is a challenge to an assumption because when faced with a problem, we often have to question our assumptions and beliefs in order to find a solution. Assumptions can limit our thinking and prevent us from seeing alternative perspectives or possibilities. By challenging these assumptions, we open ourselves up to new ideas and approaches that can help us overcome the problem at hand. Therefore, a problem serves as a catalyst for questioning and challenging our assumptions.

### A __________is an intelligent, insightful and logical guess.

Explanation
A hypothesis is an intelligent, insightful, and logical guess because it is a proposed explanation or prediction based on limited evidence or observations. It is formed through logical reasoning and critical thinking, taking into account existing knowledge and evidence. A hypothesis is intelligent because it requires understanding and analysis of the available information, and it is insightful because it offers a potential explanation or solution to a problem. It is logical because it follows a rational thought process and is based on logical deductions.

### A __________uses deductive reasoning to guess what outcome you think you'll observe.

Explanation
A prediction is a statement or guess about what will happen in the future based on deductive reasoning. It involves using available information, evidence, and logical thinking to make an educated guess about the expected outcome or result. Predictions can be made in various fields such as science, sports, weather, and personal life. They help individuals or researchers anticipate and prepare for possible outcomes or events.

### The higher the __________of recurrence, the closer a theory becomes to a fact.

Explanation
The higher the probability of recurrence, the closer a theory becomes to a fact. This means that when there is a higher likelihood or chance of something happening repeatedly, the theory supporting that occurrence becomes more reliable and closer to being considered a fact. The concept of probability is often used to measure the likelihood of events happening, and a higher probability indicates a stronger relationship between the theory and the observed outcomes.

### __________are tests to simplify observations (in nature or a lab setting) so conditions can be controlled.

Explanation
Experiments are tests conducted in order to simplify observations, whether in a natural environment or a laboratory setting. The purpose of experiments is to control the conditions under which observations are made, allowing researchers to manipulate variables and determine cause-and-effect relationships. By conducting experiments, scientists can isolate specific factors and study their impact on the outcome, thus gaining a deeper understanding of the phenomenon being studied.

• 6.

### __________is where the variables are being manipulated to test the hypothesis.

Explanation
The experimental group is where the variables are being manipulated to test the hypothesis. In an experiment, researchers divide the participants into different groups, with the experimental group being the one that receives the treatment or manipulation of the independent variable. By comparing the results of the experimental group to those of a control group, researchers can determine the effects of the manipulated variable and draw conclusions about the hypothesis being tested.

Rate this question:

• 7.

### The __________is identical to the experimental group, except for the variable being manipulated.

• A.

Control group

• B.

Variables

• C.

Hypothesis

• D.

Prediction

• E.

Fact

A. Control group
Explanation
The control group in an experiment is used as a baseline to compare the effects of the variable being manipulated in the experimental group. It is identical to the experimental group in all aspects except for the variable being studied. By comparing the results of the control group to the experimental group, researchers can determine the specific effects of the manipulated variable and draw conclusions about its impact.
