Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
Answer:
Profase - Metafase - Anafase - Telofase - Citocinesis
Explanation:
Estas fases ocurren en orden estrictamente secuencial y la citocinesis —el proceso de dividir el contenido de la célula para hacer dos nuevas células— comienza en la anafase o telofase. Etapas de la mitosis: profase, metafase, anafase y telofase. La citocinesis típicamente se superpone con la anafase o telofase.
The answer is the control group.
the group in an experiment that is not exposed to the tested variable is called the control group
Fossils can show structural similarities and differences in organisms over time revealing the vast diversity of life forms that have and continue to exist on Earth.
Comparisons between living organisms and fossils also allow scientists to make inferences about the lines of descent.
"Carpeting", and "furniture increased ventilation" inefficient indoor cook stoves "VOCs from paints".
Option: C
<u>Explanation</u>:
VOC's are really harmful solvents that are released in the air as the paint dries. The VOC's can create acute health symptoms which may result harmful after some time, like dizziness, headache, and many more. Generally, the long term effects are not that evident, but some VOC's are more carcinogens according to US environmental protection agency. Although, many paint companies claim that their paints are VOC free which is actually false. It might be true that the VOC is not present in the base of the paint, but when the pigment is added to the paint the VOC increases. Hence, carpeting, furniture, cook stoves and VOC's from paints are really harmful indoor pollutants.
