The nucleus during mitosis. Micrographs illustrating the progressive stages of mitosis in a plant cell. During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.
Answer: False
Explanation:
Active transport is the movement of molecules from a region of lower concentration to a region of higher concentration across the cell in a concentration gradient. It requires the use of energy .
Passive transport is the movement of molecules in and out of the cell from higher concentration to lower concentration without the use of energy.
locus is the best term to describe the position of gene in the chromosome. so locus is that place within the chromosome where information about a certain trait is stored. to some extent locus is interchangeable with the term gene. homologous chromosomes have identical genes in the same loci.

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.

Hope this All Helps (Hope it did)! Have A Wonderful Day! :)
