No. It is a liquid substance not a living creature that has the characteristics of life. Yes, it may have bacteria or other living creatures that thrive in water but they are their own separate form of life.
The independent variable is the water temperature because it is not dependent on the change of another variable so the answer would be D
Answer:
The answer would be B): Iron
Explanation:
Proof
Answer:
The nuclear membrane dissolves, and spindle fibers form.
Explanation:
This occurs during prophase. the chromosomes become shorter and thicker. The centrioles migrate to the opposite poles. The nuclear envelope is broken down, the nucleolus disappears, and microtubules attach to the chromosomes at the kinetochores present in the centromere. Microtubules that are associated with the alignment and separation of chromosomes are referred to as spindle fibers. Chromosomes visible under a microscope are connected at the centromere. In meiosis, the homologous chromosomes break in their DNA strands at the same point, following a recombination of the fragmented parental DNA strands into non-parental combinations, known as crossing over.
Nitrogen because it is essential for making nucleic acids and amino acids in plants. Nucleic acids make DNA and RNA and amino acids make proteins. All are needed for cell growth and repair.
