Many scientific errors can occur because the researchers does not use good skill of observation. Imagine a scenario where not being observant can result in an experiment going wrong. Describe the scenario in 3 or more sentences.
Answer:
example sentence:
One scenario could be if a researcher is trying to research if a plant grows better in the light or in the dark. The experiment could go wrong if the researcher miss writes the data of the plant growing in the dark by simply not paying close anough attention to the plant. This in turn would make the experiment faulty and ruin the entire expirement.
A Microscope has an ocular objective of 10x and a high power objective of 50x, what is the microsc
total magnification?
Answer:10X– This objective magnifies the image by a factor of 10 and is referred to as the “low power” objective. 43X (or 45X)– This objective magnifies the image by a factor of 43 (or 45) and is referred to as the “high power” objective. 100X– This objective magnifies the image by a factor of 100.

Elle wanted to test how temperature affects the rate of evaporation. She had
three setups:
Setup 1: Elle placed a container with 1 cup of water at room temperature
(25°C).
Setup 2: Elle placed a container with 1 cup of water in a warm room (45°C).
Setup 3: Elle placed a container with 1 cup of water in a cold room (0°C).
Which were the experimental groups?
A. Setups 1, 2, and 3
B. Setups 2 and 3
C. Setups 1 and 3
e
D. Setups 1 and 2
Setup 1: The system will shift toward the products
Setup 2: The system is at equilibrium
Setup 3: The system will shift toward the reactants
The experimental groups are:
Setup 1: The system will shift toward the products
Setup 2: The system is at equilibrium.
What is equilibrium?The equilibrium is defined as condition in which all acting influences are balanced or cancelled by equal opposing forces, resulting in a stable system.
Setup 3: The system will shift toward the reactants.
