What is the function of a lock screw of a microscope?
The lock screw of a microscope is used to secure the microscope stage in place once the specimen is in focus. It helps prevent any movement or vibration that could result in loss of focus during observation. Locking the stage also allows for precise positioning and manipulation of the specimen.
Why do specimens need dehydration to be viewed under a light microscope?
Dehydration removes water from the specimen, which reduces light refraction and improves image clarity. Water can scatter light and distort the image, affecting the resolution and quality of the observation under a light microscope. Dehydration also helps preserve the structure of the specimen for longer periods.
Is the cell theory a result of a hypothesis and observation of one person?
The cell theory is not the result of one person's hypothesis and observation, but rather a culmination of contributions from multiple scientists over time. It was developed based on the observations and experiments of multiple researchers, including Matthias Schleiden, Theodor Schwann, and Rudolf Virchow, who all played important roles in formulating the cell theory.
What is ocular hypertelorism?
increased width between the eyes due to an arrest in development of the greater wings of the sphenoid, thus fixing the orbits in the widely separated fetal position; autosomal dominant inheritance. Ocular hypertelorism is a feature of many syndromes. A distinct form shows other congenital defects such as hypospadias and esophageal anomalies.
What happens to a microscope with the condenser is decreased?
If the condenser on a microscope is decreased, less light will reach and illuminate the specimen, which can result in a dimmer image. It may also lead to decreased contrast and resolution, making it harder to see details of the specimen. Adjusting the condenser properly is important for optimizing the quality of the image when using a microscope.
What will happen if you use direct sunlight to observe a specimen?
Using direct sunlight to observe a specimen can result in overheating and potential damage to the specimen. Sunlight can also introduce unwanted glare and shadow effects, making it difficult to accurately observe details. It is recommended to use diffused or artificial light for controlled and optimal observation conditions.

Why do you need to record your observation when performing an experiment?
To give final result to our observation
Does a set of values mean the same as an observation?
No. One observation will normally get you onevalue, not a set of values. Also, to be precise, the observation is the act of observing; the value is the result of the observation, not the observation itself.
What type of metal is made by combining other metlals?
The result of combining different metals is an alloy.

What is a way to organize and record result and observation?
Database
What does it mean if the biopsy result said that no atypia was noted on the specimen?

What is the immediate result of a plant's egg and sperm combining?

What is an outcome in a probability experiment?
It is the result of the experiment. It is the value of the observation.
Are made by looking at the result of a behavior or occurrence.?
