Answer:
Mechanical waves(Water waves, sound waves Spring waves )Electromagnetic Waves(Light waves Heat waves)
Short tandem repeats. STRs are analyzed using polymerase chain reaction (PCR), a technique for mass-producing sequences of DNA.
Answer:
The correct answer is - a density independent factor.
Explanation:
Any external cause or change that leads to the change in the size of a population regardless of the density of the particular population known as a density independent factor in ecology.
Density independent factors are the factors that are not affected by the size of the population size of the species such as weather, climate and natural disasters.
Thus, the correct answer is - a density independent factor.
<span>The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis.
