The best option is D. Based on scientific evidence about algal bloom, it would be best to evacuate all humans from the area around the lake. Algal bloom is caused by excess nutrients in the lake. This occurrence is linked to the death of fishes, plants, mammals and birds. Also. it has been said to cause human illnesses. Thus, to avoid this, it would be best to stay away from the lake with algal bloom.

Explanation:
Becausebof he law of conservation of evergy. Evergy can not be created of eliminated, therefore it has to be transfered in this case the energy is transfered from one organism to the otherand this process continues at an endless cycle
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
