Two separate cells are made
Answer:
Explanation:
given cells at incubation = 2 million (2 x 10^6) Staph
cells at the start of incubation = 200 Staph
Total time =6hrs = 360minutes
Recalling that Number of generations = Log(cells at incubation) - Log (cells at the start of incubation)/0.301
- Number of generations = Log 2000000 - log 200 /0.301
= 20.93 generations.
- hence generation time = total time/number of generations
= 360/20.93 = 17.20minutes
as said, that the apple pie is left after 2hrs, it implies 8hrs (480minutes) will be the new total time; number of generations = total time / generation time
= 480/17.20minutes = 27.90 generations
- hence total number of bacteria after 8hrs = 2^n generations x initial number of bacteria
= 2^27.90 x 200 staph = 5.009 x 10^10 bacteria
Answer:
This is the formula used to convert Celsius to Fahrenheit.
Explanation:
Example:
Convert 55 degrees celsius to fahrenheit.
F= 9/5 x 55 + 32
9/5 x 55= 99
99 + 32 = 131
55 degrees celsius is equal to 131 degrees fahrenheit.
Because of the fact that female mammals have chromosomes from both parents (from the father and from the mother) and all cells have the same inactivated X chromosome female mammals are considered to be mosaic <span>of the maternal and paternal cells.</span>
During mitosis, the cell separates its cytoplasm, organelles and DNA equally. Mitosis is a continuous process but it is useful to divide it into four stages: prophase, metaphase, anaphase, and telophase.
1. During prophase<span>, the nuclear membrane disappears and a framework of microtubules is formed. The microtubules form spindle fibers that originate at the poles. Some spindle fibers span the entire cell and others attach to the chromosomes. The spindle fibers function to move the chromosomes. </span>
2. During metaphase<span>, each chromosome is positioned along the central axis of the cell called the metaphase plate. The centromeres are situated directly along the metaphase plate with the each chromatid positioned on opposite sides of the metaphase plate. The cell begins to elongate. </span>
3. During anaphase<span>, each centromere splits into two, causing sister chromatids to separate. Once separated, each chromatid is considered a chromosome and the once-joined sisters are pulled to opposite poles of the cell by the microtubules. Also during anaphase, the entire cell begins to elongate and, therefore, further separates the sister chromosomes. </span>
4. During telophase, a daughter nuclei begins to form at each pole, enveloping the gathered chromosomes. Finally during cytokinesis, the cytoplasm divides resulting in two genetically identical daughter cells. <span>
