Hello!
Could be either:
<span>The action or process of observing something or someone carefully or in order to gain information.
</span>
Or
<span>A remark, statement, or comment based on something one has seen, heard, or noticed.
</span>
And in Science:
<span>An 'observation' in the scientific sense, is when you make a measurement or evaluation of some sort. You would usually make a note of how something has changed sine the previous ovbservation. Maybe the temperature has changed: gone up one degree; or a crystal has grown: maybe it is now .1 centimeters longer.
"Observations" usually implies that you are watching some process, and either measuring or noting the change that has taken place. usually you will also want to note the time of the observation, so that you can have an idea of how quickly (or slowly) the changes are occurring.
</span>
Hope this All Helps (Hope it did)! Have A Wonderful Day! :)
<span>Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips. </span>
False Routine maintenance costs on a hybrid may be lower than on a regular car.
A variation is a reference to the differences or deviations, such as the structure and form, as for crossing over is the exchange of genetic material between the non-sister chromatids of the homologous chromosomes during meiosis.
Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Other Info That Might Help:
In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.
