When cell over divide they cause a sickness or cancer
Answer:
Fungus, A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, those being Plantae, Animalia, Protozoa, and Chromista.
Explanation:
Fungi and animals are very different from each other and classified as completely separate kingdoms. At the cellular level, both animals and fungi are composed of eukaryotic cells. Fungal cells differ from plant cells in that they do not have chloroplasts and cannot carry out photosynthesis to make their own food.
The correct answer is: 100x.
The calculation of total magnification of the microscope includes multiplying the magnification of the lenses together, So, to calculate the total magnification take the power of the objective (10X) and multiply by the power of the eyepiece, ocular lens (10X).
Answer:
True
Explanation:
Energy sees a 90% decrease as it moves up trophic levels because energy is lost as metabolic heat during the transfer of energy.
Answer:
No 15N/15N labeled DNA was observed in second generation
Explanation:
Meselson and Stahl were doing an experiment to find out the semi-conservative mode of replication of DNA. The first cultured bacteria in 15N medium which was containing a heavy isotope of nitrogen. The DNA synthesized here had more density. After that they transferred the bacteria to the 14N containing medium. When bacteria reproduced and new strands of DNA were synthesized, they observed the following -
- The first generation had hybrid DNA with 15N/14N strands
- The second generation had both hybrid 15N/14N DNA and 14N/14N DNA strands
- There was no 15N/15N DNA observed.
In this way they proved that one strand of DNA is kept conserved during the replication.
