Reactivity i am pretty sure
It is not, 'imminent,' since the ozone layer in the atmosphere is slowly repairing itself. However, that being said, there is lots the human race can do to stop global warming. It may have more effect in 30 years time, but, if humans do enough, we can stop worrying. Renewable energy is a good idea to prevent global warming. Since most of it is generated from Co2 emissions from generating power. Electric cars are also good, because if we can make renewable energy (such as wind or solar power, or hydroelectric power for that matter) to power them, they will not produce emissions either.
Answer:
E. They decrease the rate at which Ras hydrolyzes GTP.
Explanation:
Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.
Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.
Because our eyes see what's reflected not absorbed. Leaves contain chlorophyll which contains a pigment of green that absorbs red and blue wavelengths, while reflecting green.
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
