Answer:
I think its the third one :)
Explanation:
hope this helped :))
Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
Answer:
The correct option is B) analyze the results and make a conclusion
Explanation:
The scientific method of research is based on the following steps:
Observations are made: In the following scenario, a student observed that t when bananas are kept near other fruits, the other fruits ripen faster.
Question: Based on the observation, a question is generated. In this scenario, the student had a question that will keeping bananas near any fruit increase the ripening process of the fruit.
Hypothesis: A hypothesis is the formation of a tentative statement.
Experiments: Based on the hypothesis, experiments are done to check for the results.
Analyzing the results and drawing conclusions: Results from the experiments are analyzed and conclusions are drawn which might prove the hypothesis to be correct or wrong.
Answer:
Explanation:
1. Over time more and more molecules of DCPIP would be decreased by electrons taken from plastoquinone (Pq). This statement is true in the sense that DCPIP is an artificial electronic acceptor which is decreased by taking electrons from plastoquinone.
2.) Water splitting by Photosystem II would occur at higher levels than if the drug were administered without DCPIP. This statement is true.
3.)Events in Photosystem I would occur just as they would in the absence of drug and DCPIP. This statement is false because the drug obstructs the electron transport from plastoquinone to cytochrome B. So the events are abnormal because no protein transfer is involved in this mechanism.
